Value Collection 201103P Button Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 201103P is a button socket cap screw designed for applications where a low-profile fastener head is required. It features a 1/4-20 UNC thread with a 1-inch length under head and is driven by a 5/32-inch hex socket. Manufactured from alloy steel with a black oxide coating, this screw meets ANSI/ASME B18.3 and ASTM F835 standards. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it well suited for mechanical assemblies, fixtures, and equipment panels. Hardness is rated at 36-43 HRC, and the thread fit is Class 3A for close-tolerance installations.

This screw is used in a wide range of industrial, mechanical, and maintenance applications where a smooth, rounded head profile is preferred over a standard hex cap. Common installation scenarios include machine guards, panel enclosures, brackets, and equipment frames in both light industrial and commercial settings. The fully threaded shank and right-hand thread direction make it straightforward to drive into tapped holes or use with a matching nut. Installers in fabrication, HVAC equipment assembly, electrical enclosure work, and general mechanical trades will find this fastener a practical choice for flush or near-flush fastening needs.

Key Features

• Low-profile button head reduces snag points in tight assemblies
• 1/4-20 UNC thread, 1-inch length under head, fully threaded shank
• 5/32-inch hex socket drive for standard ball-end or straight hex keys
• Alloy steel construction with 36-43 HRC hardness rating
• Black oxide coating for mild corrosion resistance and low reflectivity
• Meets ANSI/ASME B18.3 and ASTM F835 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or general-use fastener for any tapped 1/4-20 UNC threaded hole requiring a button head socket cap screw per ANSI/ASME B18.3 specifications.

Installation Notes

Installation requires a 5/32-inch hex key or ball-end driver. Verify the receiving hole is tapped to 1/4-20 UNC Class 3B before driving. Power down or de-energize any equipment before accessing fastened assemblies on live electrical or mechanical systems. Do not exceed the rated hardness limitations of the mating material to avoid thread stripping.
