Ring Terminal Sizes: Wire Gauge, Stud Size and the Types You Can Choose

By VoltixC Engineering Team · Last updated: 2026-09-28

Fast answer: Ring terminal sizes are read from two numbers: the wire range the barrel accepts, such as 22–16, 16–14 or 12–10 AWG, and the stud size the ring fits, such as #8, #10 or 1/4 inch. Pick a ring of the same nominal size as the stud, then choose vinyl or nylon insulation for the environment.

A ring terminal is a crimp terminal whose flat tongue ends in a closed ring, so a screw or stud passes straight through it. Catalogues also call it a ring connector, a ring lug or a wire eyelet. VoltixC lists 69 insulated ring terminals in two series, RV with a vinyl sleeve and RNY with a nylon sleeve, from 16–14 AWG to 6 AWG on the ring terminals page.

Ring terminal sizes at a glance: which numbers set the part?

Two numbers set a ring terminal: the wire range its barrel accepts and the stud size its ring fits. Sleeve material, barrel type and finish are picked after those two.

SYSTEM · RING, SCREW AND STUD

What is a ring terminal, and why does the closed ring matter?

A ring terminal is a crimp terminal with a closed ring on its tongue, and the screw has to come out before the ring can leave the stud.

ProblemWhat to doCheck
The wire must stay on the stud if the screw backs offChoose a ring terminal. According to Wiltronics, a ring terminal is chosen where the fastener passes through it, so the connection cannot be removed without loosening or removing the fastenerThe ring stays on the stud with the screw half out
The joint sits on a screw terminal that is opened only for serviceUse a ring. Electrical Engineering Portal notes that loop or eye connections at screw terminals are inexpensive and are used where the connection would be infrequently disconnectedThe terminal is not on a test or swap point
The wire is swapped on and off a screw many timesLook at a fork terminal; the fork and spade terminal guide compares themThe fork can leave with the screw loosened a turn
The sleeve colour is the only marking you can seeRead it as that maker’s code. According to ABB’s Spec-Kon guide, insulated terminals use colour-coded insulators according to DIN cable sizesThe wire range on that maker’s data sheet covers your wire
The cable is heavier than 6 AWGMove to a copper tube ring terminal; the RNY list stops at 6 AWGThe part is on the copper tube ring terminals page
You are unsure the part is a ring terminalLook for a crimp barrel, a sleeve and a flat tongue with a full ringThe ring is a closed circle with no slot, sized to one bolt or stud

Ring terminals land on terminal blocks, grounding studs, battery and busbar studs and panel screws, wherever a wire ends under a nut. The RV and RNY parts sit on the ring terminals page, and the wider insulated range is under crimp connectors.

DATA · 2 NUMBERS

What do the two numbers on a ring terminal mean: wire range and stud size?

On a 16–14 AWG wire going to a #10 screw, the 16–14 AWG range picks the barrel and #10 picks the hole in the ring.

PROCESS · 7 STEPS

How do you crimp and mount a ring terminal?

Match the part to the wire and the stud, strip, insert, crimp in the matched nest, pull-test, then fit the ring over the stud and tighten it to the equipment maker’s torque.

  1. Pick the barrel from the wire gauge and the ring from the stud name on the drawing.

    Both the AWG band and the stud name on the part match your list.

  2. Strip the wire to the length of the metal barrel.

    Held next to the terminal, the bare copper reaches from the barrel end to its mouth.

  3. Push the stripped end in until the conductor reaches the far end of the barrel.

    No strand is folded back or left outside.

  4. Close the crimp tool through its full stroke in the nest marked for that wire range.

    The indent sits on the barrel and clear of the ring tongue.

  5. Give the wire a steady, in-line pull.

    If the terminal moves at all, cut it off and crimp a new one.

  6. Take the screw or nut off, slide the ring over the stud and refit the screw.

    The ring lies flat under the washer or nut, with the tongue clear of its neighbour.

  7. Tighten to the torque the equipment maker gives for that terminal.

    After tightening, the tongue has not turned and the sleeve is not crushed.

StepWhat the source saysFor a ring terminal
InsertAccording to TE Connectivity, a funnelled wire entry prevents turned-back strands and speeds wire insertionPush the strands straight in; a funnel entry helps, and the strands still need a square strip
PullWiltronics advises that a crimp that moves or pulls out in a steady in-line pull test should be cut off and redone with a new terminal, and crimped terminals should not be reusedCut off a ring terminal that moved and crimp a new one

The full crimping method, from choosing the die to the pull check, is in how to crimp wires. Torque values are not given here, since they belong to the terminal block or the equipment.

Tip

Tip: Crimp one ring terminal on a spare length of the same wire and pull it before you set up the batch.

DATA · 7 MISTAKES

Which ring terminal sizing mistakes are most common?

A ring terminal ends up wrong when its barrel or ring is chosen from a name, a colour or the jacket size instead of the conductor and the stud.

ProblemWhat to doCheck
The barrel was chosen from the outside diameter of the cableSize it from the conductor. According to Wiltronics, installers should size a connector from the conductor size printed on the cable, not from the cable’s outside diameter aloneThe AWG band on the part covers the gauge printed on the jacket
The sleeve will not close on a thick jacket, or rattles on a thin oneCheck the jacket too. TE Connectivity explains that insulation outside diameters vary among wires with the same AWG size, so the insulation barrel must accommodate the wire’s outside diameter and the crimp range must match itThe sleeve grips the jacket with no gap
The ring is one size larger than the studOrder the ring for the stud named on the drawing, not for the size of the bolt guessed by eyeThe washer covers the ring, and the ring cannot slide sideways
An M5 ring went on a #10 screw, or a 5/16 in ring on an M8 studTreat the two names as two sizes and order the one on the drawingThe bolt passes through the hole without forcing and without play you can feel
Five or more rings are stacked on one studMove the extra wires. According to West Marine, no more than four terminals should be secured to one terminal stud under ABYC E-11.14.4.1.10; extra connections need additional studs joined by jumpers or copper strapsFour rings or fewer on each stud
A vinyl sleeve sits next to a hot partRead the rating of that exact model and choose a part rated for the heat thereThe printed rating covers the temperature at the joint
The terminal was crimped with pliers or the wrong nestCut it off and crimp a new one in the nest marked for the wire rangeThe indent is centred on the barrel

Put the conductor gauge, the jacket outside diameter and the stud name on each order line, and try one crimped sample on the stud before the batch is made.

Caution

Caution: Cut off and replace a ring terminal that failed the pull test; a second squeeze on the same barrel leaves the fault in place.

NEXT STEP · 69 PARTS

Where can you check VoltixC ring terminals and the size lookup tool?

The insulated ring terminals page lists 69 VoltixC parts in two series, RV vinyl and RNY nylon, and the size lookup tool finds the series from your wire gauge and sleeve.

Source: supplier specification sheets, RV and RNY series; not individually re-tested. 69 part numbers are in the full specification table, with the hole, tongue width and length for each; request the complete list with your quote.

The 14–12 AWG band is RV only, and 8 AWG and 6 AWG are RNY only. Send one line per size with the fields below.

  • The wire gauge as printed on the jacket, and the jacket outside diameter if it is thick
  • The stud name for each end, copied from the drawing
  • Vinyl or nylon, and the finish you want
  • The quantity for each size, and any tongue shape other than a standard ring

Gauges outside 16–14 AWG to 6 AWG are not on the current list for these two series, so ask before you specify 22–16 AWG parts. For heavier cable, the tinned copper tube lugs page and the copper lug size chart cover copper tube terminals. To prove the fit on your equipment, ask for one or two sizes as samples first; fastest sampling is 7 days. MOQ, packing and lead time are confirmed per order.

FAQ about ring terminal sizes

What two numbers define a ring terminal size?

The wire range and the stud size. The sleeve and the finish are picked after that.

Does an M5 bolt equal every #10 ring?

M5 and #10 are two different sizes that happen to sit close together. The drawing decides which one you buy, and a bolt pushed through a sample ring shows whether it fits. Electrical Engineering Portal’s inspection guidance checks the bolt diameter relative to the lug fixing hole.

Why can a ring hole be too large?

With a hole that is too big, the nut presses on a thinner band of the ring and the tongue can swing on the stud. West Marine’s summary of ABYC E-11.14.4.1.11 calls for ring terminals of the same nominal size as the stud.

When is a closed barrel preferred?

When the terminal is crimped by hand in a die nest. The closed tube holds every strand in place as the nest closes, while an open barrel is made for the tooling its maker names. The barrel form of RV and RNY parts is confirmed per order, and an open-barrel part named on a drawing is quoted from its part number.

Which insulation suits vibration?

A nylon sleeve made for a double crimp. Many nylon-insulated terminals are designed for double crimping, which adds strain relief and tensile strength (Waytek). VoltixC lists that sleeve in the RNY series, from 16–14 AWG to 6 AWG, while the vinyl RV series suits dry, still panels.

Can one ring fit several stud standards?

One ring can serve several when a sample ring takes a bolt of each stud type without forcing and with little play. Where one wire has to land on two different studs, two parts are the safer order, and each hole is confirmed per order once both stud names are on the enquiry.

What size ring terminal fits an M8 stud?

A ring listed for M8, with the barrel taken from your wire gauge. ABB’s Spec-Kon table, as one maker’s example, offers non-insulated copper ring terminals for 4.0–6.0 mm² conductors with M4 through M12 stud-hole sizes. On RV and RNY parts an M8 ring is not on the current list, and 5/16 in, with an 8.4 mm hole, counts as a separate size.

METHOD NOTE

How this guide was written: part codes, wire bands, stud sizes, hole diameters, sleeve colours and the tin-plated copper body come from the VoltixC supplier specification sheets for the RV and RNY series, which give no current or temperature rating. The sizing rules and maker examples come from West Marine’s summary of ABYC E-11, ABB, Phoenix Contact, TE Connectivity, Waytek, Wiltronics, Electrical Engineering Portal and UL Standards & Engagement. VoltixC ran no tests for this guide. It gives no current, pull-force or torque values of its own, and the supplier rows have not each been re-tested.
