U.S. Socket Head Set Screws

U.S. Socket Head Set Screws

U.S. socket head set screws are compact fasteners used to hold one component firmly against another without a traditional nut. Their headless design and internal hex drive make them useful in machinery, automotive, industrial, and equipment applications.

Flush, Low-Profile Holding Power

Socket head set screws are commonly used to secure collars, pulleys, gears, knobs, and other components onto shafts or within assemblies. The internal hex drive allows installation with an Allen wrench or hex key, while the headless design allows the screw to sit flush with or below the surface.

These fasteners are practical when a standard bolt head would interfere with clearance, movement, appearance, or service access.

Useful for Shafts and Compact Assemblies

Use U.S. socket head set screws when fastening components in tight spaces, replacing worn set screws, or securing parts that need strong holding power without extra bulk.
