Value Collection 581242PR Hex Socket Cap Screw 8-32 Unc

Product Description

The VALUE COLLECTION 581242PR is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength threaded fastener. It features an 8-32 UNC thread with a 0.125-inch length under the head and is fully threaded along its entire shank. The screw is driven with a 9/64-inch hex key. Constructed from alloy steel with a black oxide finish, it offers corrosion resistance and is well suited for use in machine assembly, tooling fixtures, and general mechanical work where a flush or countersunk fastening solution is needed. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards.

This screw is commonly used in light-duty machine assembly, jig and fixture work, electronic enclosures, and precision equipment where close-tolerance threading and a low-profile socket head are required. The 8-32 UNC thread is a widely used coarse-pitch unified thread, making this screw compatible with standard tapped holes in metal components across industrial, commercial, and maintenance applications. It is installed by machinists, maintenance technicians, and mechanical assemblers working with standard UNC-threaded stock.

Key Features

• 8-32 UNC fully threaded shank for consistent engagement through the full length
• 0.125-inch length under head for compact, flush fastening in tight clearances
• 9/64-inch hex socket drive compatible with standard hex keys and Allen drivers
• Alloy steel construction meets ASTM A574 high-strength fastener specification
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards for socket cap screws

Compatibility

Designed as an OEM-style replacement and general-use fastener for standard 8-32 UNC tapped holes in metal assemblies, fixtures, and enclosures.

Installation Notes

Install using a properly sized 9/64-inch hex key or socket driver to avoid rounding the drive recess. Ensure the receiving tapped hole is clean and free of debris before threading. Do not exceed the torque capacity appropriate for the fastener grade and material being joined. Follow applicable ASME or industry fastener standards for thread engagement depth and preload requirements.
