Do It 300985 C-clamp 4 Inches Malleable Steel

Product Description

The DO IT 300985 is a 4-inch C-clamp built for general-purpose clamping in fabrication, woodworking, and mechanical service work. The body is cast from malleable steel with a gray surface finish, and the screw and swivel are carbon steel precision machined for smooth, consistent thread engagement. At 1.42 pounds, it provides solid holding force without excessive bulk. This clamp is a standard hand-tool staple used by tradespeople and contractors who need reliable, repeatable clamping pressure on the job or at the bench.

The 300985 is suited for residential and light commercial applications where a durable, mid-size C-clamp is required. Typical use cases include securing workpieces during welding, holding assemblies during glue-up, or stabilizing components during mechanical repair. The 4-inch throat depth accommodates a wide range of material thicknesses and stock sizes commonly encountered in trade and shop environments.

Installation Notes

Do not exceed the rated clamping capacity of the clamp, and inspect the screw and body for cracks or deformation before each use.
