304 Stainless Steel C-Shaped Adjustable Clamp

Product Details

Everything you need to know — features, specs, fitment, and answers to the most common questions.

304 stainless steel body and screw

No rust rings on wet lumber, no seized threads after the wash bay — clamps that survive coastal and shop life.

Smooth, honest clamping force

Clean-cut threads deliver pressure without the gritty binding of corroded clamps.

Swivel pad seats on angled stock

The pad conforms so pressure lands flat instead of point-loading and denting the work.

Lifetime warranty — no receipt

If it fails under normal use, we replace it. Ships same-day from Columbus, OH.

Is stainless strong enough compared to a forged steel clamp?: For fixturing, glue-ups, and holding work, yes — with the bonus that it will not corrode. For extreme crush-force pressing applications, use a dedicated press.
Warranty details?: Lifetime warranty. If it fails under normal use we replace it — no receipt, no questions.
Shipping?: Same-day dispatch from Columbus, OH for orders in by 2pm ET. Free standard shipping at $49 and up.

Stainless clamp that laughs at shop abuse

Regular C-clamps rust and gall in our wash bay area. These 304 stainless ones thread smooth after months around coolant and spatter. Clamping force is honest and the swivel pad seats flat on angled stock.

Salt air does not touch it

Everything mild steel dies fast on the dock. This clamp has held fixtures on outboard brackets through a season of salt spray and still spins free. Stainless was the right call for marine work.

Glue-ups and repairs, no rust rings

Used it for outdoor furniture glue-ups where my old clamps left rust stains on wet oak. Clean pressure, no marks, easy adjustment range. A deeper throat version would be a nice companion.
