Value Collection 872147PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 872147PR is a hex socket cap screw designed for fastening applications that require a clean, low-profile head and reliable clamping force. The screw features a 1/4-20 UNC thread and a 3/16 inch hex drive socket, accepting a standard hex key or Allen wrench. With a 5/8 inch length under the head and full threading along the shank, this fastener provides consistent thread engagement from head to tip. The base material is alloy steel with a zinc-plated finish that provides basic corrosion resistance in indoor and light-duty environments. It conforms to ASME B18.8 and ASTM A574 standards, making it a recognized option for mechanical assemblies where a torque-rated socket head cap screw is specified.

This screw is suited for use in machine assemblies, tooling fixtures, equipment enclosures, and general mechanical fabrication. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes, making this fastener widely applicable in both OEM manufacturing and maintenance-and-repair operations. The hex socket drive is preferred in confined spaces where a hex key provides better access than a standard hex head driver. This item is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock or production use.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 3/16 inch hex socket drive for use with standard Allen or hex key tools
• 5/8 inch length under head, fully threaded shank
• Alloy steel construction meets ASTM A574 for strength requirements
• Zinc-plated finish provides basic corrosion resistance for indoor applications
• Conforms to ASME B18.8 dimensional standard

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application requiring an ASME B18.8 or ASTM A574 compliant fastener in that thread size.

Installation Notes

Installation requires a 3/16 inch hex key or Allen wrench. Ensure the mating tapped hole is clean and meets 1/4-20 UNC thread specification before driving the fastener. Apply thread-locking compound or fastener lubricant as required by the application spec. Do not exceed the rated mechanical limits of the alloy steel material by over-torquing, which can strip threads or cause fastener failure.
