Description
This is a black socket set screw designed to hold components securely without a protruding head, ideal when a flush fastening is needed. Made from steel with a plain black finish and USS coarse #8-32 threading, its 3/8-inch length suits light- to medium-duty fastening tasks in furniture assembly, machine maintenance, or equipment adjustments where a discreet, reliable clamp point is required. The socket drive lets you tighten or remove the screw with an Allen key for precise torque control, useful when aligning shafts, securing collars, or locking gears without marring surrounding surfaces. Manufactured in the U.S., this screw provides straightforward compatibility with common #8-32 threaded holes and components, making it a practical choice for hobbyists and professionals tackling repair, retrofit, or custom build projects.
