Wilton 408SF C-Clamp 8-1/4 in 6900 lb

The Wilton 408SF is a regular-duty C-clamp built for metalworking, welding and general fabrication tasks that require a strong, visible grip. Its forged steel body and high-visibility yellow powder coat make it easy to spot on a busy bench or job site.

8-1/4 in jaw opening and 6900 lb clamping force

The clamp opens from zero to 8-1/4 inches with a throat depth of 4 15/16 inches, giving enough reach for thick workpieces and wide flanges. The 6900 lb force handles heavy structural steel, but the standard thread and sliding T-handle limit speed on repetitive high-volume jobs.

Forged steel body with swivel pad and sliding

The single forged steel spindle carries a black-oxide finish and a V-grooved anvil with an included swivel pad to protect finished surfaces. The sliding T-handle provides leverage for tightening, while the OSHA safety yellow coating meets visibility standards without needing extra markers or paint.

Questions about this item

Will the 6900 lb clamping force of this Wilton 408SF C-Clamp damage older wooden workpieces I still use?

The forged steel body and V-grooved jaw pad with swivel pad distribute the 6900 lb force evenly, reducing marring on softer materials like wood when pads are clean and properly aligned.

How can I verify the 8-1/4 in maximum jaw opening is functioning correctly after first use?

Open the sliding T-handle fully until the spindle stops; the gap between the anvil and swivel pad should measure 8-1/4 inches and the black oxide spindle should turn smoothly without binding.

Does the box include the swivel pad shown in the specs or must I buy it separately?

The swivel pad is included with the clamp as a single forged steel unit; no separate purchase is needed for the V-grooved jaw pad or sliding T-handle components.
