Value Collection 701131PR Button Socket Cap Screw 1/4-20 X 3

Product Description

The VALUE COLLECTION 701131PR is a button socket cap screw designed for mechanical assemblies where a low-profile fastener head is required. Sized at 1/4-20 x 3 inches with a fully threaded shank, it uses a 5/32 inch hex socket drive and conforms to ANSI/ASME B18.3 and ASTM F835 standards. Manufactured from alloy steel with a black oxide coating, it delivers corrosion resistance and a hardness rating of 36-43 HRC. This screw is installed by machinists, maintenance technicians, and mechanical assemblers working in general industrial and manufacturing environments.

This fastener suits applications where a flush or near-flush head profile reduces snag points or interference with mating parts. The UNC thread form and 3A thread fit class ensure consistent engagement with standard tapped holes. Black oxide finish makes it appropriate for low-moisture indoor mechanical assemblies. It is commonly used in machine frames, fixtures, tooling, and light structural connections requiring a button-head profile.

Key Features

• Button head profile provides a low-profile alternative to standard socket cap screws
• 5/32 inch hex socket drive for precise torque application with a standard hex key or driver bit
• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide coating for surface protection and reduced light reflection
• Fully threaded shank with UNC 1/4-20 thread form and 3A fit class
• Meets ANSI/ASME B18.3 and ASTM F835 standards

Compatibility

Designed as a standard UNC-thread button socket cap screw compatible with any 1/4-20 tapped hole or nut conforming to ANSI/ASME B18.3 specifications.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 5/32 inch hex key or socket driver. Always ensure the mating tapped hole is clean and free of debris before fastener insertion. De-energize and lock out any equipment before fastening components on live machinery. Do not exceed the torque capacity appropriate for the thread size and material being joined.
