Socket Head Cap Screws 4-40x1" (4) (DUB312)

Socket Head Cap Screws, 4-40, 1 inch long, come in a four-pack for convenient use in compact assemblies. They’re designed for secure, recessed-drive fastening and are tightened with an Allen wrench to keep components firmly in place in tight spaces.

Finished in black oxide, these screws offer a discreet, durable coating that works with standard 4-40 threaded holes. The 1-inch length suits thicker materials or multi-component stacks, and the four-pack helps keep a ready supply on hand for ongoing projects.
