Value Collection 872153PR Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 872153PR is a hex socket cap screw designed for fastening applications requiring a recessed hex drive interface. Manufactured from alloy steel with a zinc-plated finish, this screw offers corrosion resistance in light-duty environments. The 1/4-20 UNC thread form pairs with the fully threaded 1-inch length under head to provide consistent clamping force along the full shank. A 3/16-inch hex drive (Allen key) interface is required for installation. This fastener meets ASME B18.8 and ASTM A574 standards, making it appropriate for structural and mechanical assembly work performed by machinists, millwrights, and maintenance technicians.

This screw is suited for general industrial, mechanical, and maintenance assembly applications where a low-profile socket head fastener is required. The 1/4-20 UNC coarse thread is one of the most common inch-series thread sizes in North American equipment manufacturing, making this screw a standard fit for a wide range of fixture, bracket, and panel fastening tasks in both light industrial and commercial settings. The zinc plating provides a degree of protection against oxidation in indoor or mildly humid environments.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard inch-series tapped holes
• Fully threaded along the 1-inch length under head for maximum thread engagement
• 3/16-inch hex socket drive interface — requires standard Allen wrench or hex bit
• Alloy steel construction meets ASTM A574 mechanical requirements
• Zinc-plated finish provides light corrosion resistance for indoor and protected environments
• Conforms to ASME B18.8 dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application with a 1/4-20 tapped hole requiring a recessed hex drive fastener.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen-style driver bit; use of the correct drive size prevents cam-out and socket rounding. Verify that the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or threadlocker as required by the assembly specification. Follow torque specifications defined by the equipment manufacturer or relevant ASME standards for 1/4-20 fasteners.
