Value Collection 201021P Button Socket Cap Screw 6-32

Product Description

The VALUE COLLECTION 201021P is a fully threaded button socket cap screw designed for applications requiring a low-profile head and reliable clamping strength. Sized at 6-32 UNC with a 3/8-inch length under head, this fastener is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a clean, non-reflective appearance. The 5/64-inch hex socket drive requires a standard hex key or bit. Hardness is rated at 36-43 HRC, meeting the mechanical requirements of ANSI/ASME B18.3 and ASTM F835. This screw is installed by machinists, maintenance technicians, and assembly professionals across a wide range of industrial and mechanical applications.

The 201021P is suited for use in machine assemblies, equipment enclosures, panel mounting, and general mechanical fastening where a button-head profile is preferred over a standard socket head. The low-profile domed head reduces snag points and distributes load across a wider bearing surface than a flat-head style. Its UNC thread form and Class 3A thread fit make it compatible with standard tapped holes and threaded inserts in metal components. Applications span light industrial equipment, fixtures, and fabricated assemblies.

Key Features

• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 6-32 UNC fully threaded button socket cap screw with a 3/8-inch length under head in alloy steel with black oxide finish.

Installation Notes

Install using a 5/64-inch hex key or matching socket bit. Ensure the mating tapped hole is clean and free of debris before driving. Do not exceed the torque capacity appropriate for the 6-32 thread size and alloy steel grade. Power down or de-energize any equipment fully before accessing fastened assemblies during service.
