Description
This button-head socket cap screw from HILLMAN is a #8-32 x 1" fastener designed for applications where a low-profile, finished appearance and reliable threaded engagement are important. Machined from steel alloy and finished in black oxide, the button head provides a smooth, rounded top while the internal hex socket allows for precise torque with the appropriate driver. The USS coarse #8-32 thread delivers strong holding power in many metal and composite assemblies, making these screws suitable for furniture hardware, light machinery, brackets, and trim work where a less obtrusive head is preferred. Made in the U.S., the durable steel construction and dark finish help hide wear and blend with darker surfaces or hardware. Keep a selection on hand for repair, retrofit, and general fastening tasks that call for a neat, secure connection.
