Two Ways to Clamp: Locking Pliers vs Screw-Action

"C-clamp" and "G-clamp" are the same tool by two different names — American and Australian — but AIMS stocks two genuinely different mechanisms under this collection: quick-release locking pliers and traditional screw-action clamps. Picking the right one comes down to how often you need to reposition the clamp during a job. Not sure which one suits your job? Our Clamp Types Guide: G-Clamp, F-Clamp, C-Clamp, Quick & Locking Clamps covers selection in detail.

Locking C-Clamp Pliers

Lockjaw, Trax and Excision locking C-clamps close with a squeeze-and-lock trigger instead of winding a screw thread, so you can clamp and release one-handed and reposition quickly during welding or fit-up. Lockjaw's range is manufactured from chrome molybdenum steel and runs from 230mm to 455mm overall length, including a self-adjusting extended-reach model and a swivel-pad version with a 63mm jaw opening for parallel contact on welding tables. Trax and Excision add locking C-clamp pliers from 169mm to 300mm.

Screw-Action G-Clamps

The Trax G-Clamp is the traditional screw-thread design familiar from the workshop bench — wind the screw down onto the work for steady, even pressure that holds without a trigger mechanism to maintain. AIMS stocks the Trax G-Clamp in 75mm, 100mm and 150mm jaw openings, suited to woodworking, metalworking and general fabrication holding.

Fabrication & Welding Table Fixturing

The Strong Hand PT09 table-mount locking clamp has a 102mm capacity and an M8 thread for bolting to a welding table or jig, giving repeatable fixturing job after job. The Strong Hand MGK53 uses a C-clamp base to bench-mount a grinder rest accessory rather than clamp a workpiece directly. Strong Hand Tools is an American fabrication and welding workholding brand supplying clamps, welding magnets and accessories to Australian fabrication workshops.

Choosing the Right Size

For a screw-action clamp, two dimensions matter: jaw opening (the widest gap it can span) and throat depth (how far in from the edge it reaches). For locking C-clamp pliers, overall length is the key spec — it sets both reach and leverage. Match jaw opening to your workpiece thickness with a little margin, and pick overall length for the reach the job needs. AIMS staff can help you match a clamp to a specific job — call (02) 9773 0122 if you're not sure which size to order.

Frequently Asked Questions

What is a C-clamp used for?

A C-clamp (also called a G-clamp) holds a workpiece in place while you weld, drill, glue or machine it. AIMS stocks both screw-action G-clamps and quick-release locking C-clamp pliers for welding, fabrication and general workshop holding tasks.

What's the difference between a C-clamp and a G-clamp?

Same tool, different name — C-clamp is the American term, G-clamp is what most Australian tradespeople call it. Both describe a fixed-frame clamp with a C- or G-shaped body, and AIMS lists this collection under both names since Australians search for either.

How is a C-clamp sized?

For a screw-action clamp, jaw opening (the widest gap it can span) and throat depth (how far in from the edge it reaches) are what matter. AIMS stocks jaw openings from 75mm to 150mm in the Trax G-Clamp range, plus a 102mm-capacity Strong Hand table-mount clamp. Locking C-clamp pliers are instead sized by overall length, from 169mm to 455mm.

Are C-clamps suitable for welding?

Yes — locking C-clamp pliers and table-mount clamps are commonly used for tacking and fit-up in welding and fabrication, and the Strong Hand PT09 bolts directly to a welding table for repeatable fixturing. As with any clamp used near a weld, don't use it as a current path for the welding circuit — use a dedicated earth clamp on the work itself.

What's the difference between a locking C-clamp and a screw-action clamp?

A locking C-clamp (Lockjaw, Trax, Excision) closes with a squeeze-and-lock trigger, so you can clamp and release with one hand and reposition quickly. A screw-action G-clamp (Trax) winds a threaded screw down onto the work for steady, even pressure — better suited to jobs where you want to fine-tune the clamping force.

What material are AIMS C-clamps and G-clamps made from?

Lockjaw locking pliers and C-clamps are manufactured from chrome molybdenum steel for strength and durability. For the frame material of other brands in this range, check the individual product listing or ask the AIMS team — we're happy to confirm before you order.

What should I check before buying?

Jaw opening (the widest gap the clamp needs to span), throat depth or overall length (the reach you need), and whether a locking/quick-release action or a screw-action best suits how often you'll be repositioning the clamp. AIMS staff can help — call (02) 9773 0122.
