Value Collection 201095P 1/4-20 X 1/2 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 201095P is a fully threaded button socket cap screw designed for general-purpose mechanical fastening applications. It features a low-profile button head driven by a 5/32-inch hex socket, making it well-suited for assemblies where clearance above the fastener is limited. Manufactured from alloy steel with a black oxide finish, it meets ANSI/ASME B18.3 and ASTM F835 standards. The 1/4-20 UNC thread in a 3A fit class ensures reliable engagement with standard tapped holes. Hardness is rated at 36-43 HRC, providing high tensile strength appropriate for structural and mechanical fastening tasks.

This screw is used in a wide range of light industrial, mechanical, and equipment assembly applications. It is a common choice when a low-profile head is needed in paneling, brackets, enclosures, or machinery guards. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it suitable for indoor mechanical environments. Maintenance technicians, millwrights, and general tradespeople regularly use button socket cap screws in equipment repair and fabrication work.

Compatibility

Designed as a standard 1/4-20 UNC button socket cap screw for use in any tapped hole or nut conforming to 1/4-20 UNC thread standards per ANSI/ASME B18.3.

Installation Notes

Install using a 5/32-inch hex key or socket bit driver. Power down or de-energize any equipment before accessing fastener locations in live assemblies. Do not exceed the rated hardness class when substituting into safety-critical structural joints. Ensure mating threads are clean and free of debris before installation to maintain proper thread fit.
