Value Collection 872165PR Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 872165PR is a hex socket cap screw engineered for general industrial and mechanical fastening applications. It features a 1/4-20 UNC thread size and measures 2.5 inches in length under the head. Drive engagement is accomplished with a 3/16-inch hex key. The screw is partially threaded and manufactured from alloy steel with a zinc-plated finish that provides basic corrosion resistance in dry to mildly humid environments. This fastener meets ASME B18.8 and ASTM A574 standards, making it suitable for use in structural and mechanical assemblies where consistent clamping force and dimensional accuracy are required. Machinists, maintenance technicians, and assembly professionals commonly install this type of fastener.

This hex socket cap screw is used across a broad range of industrial, commercial, and light mechanical applications. Typical uses include machine frames, equipment panels, jigs, fixtures, and general-purpose assemblies where a recessed drive is preferred to keep a low-profile head and allow flush or near-flush seating. The zinc plating makes it appropriate for interior or protected environments. It is sold individually but requires a minimum order of 100 pieces per order.

Key Features

• 1/4-20 UNC thread size for broad compatibility with standard tapped holes
• 2.5-inch length under head suits deeper engagement applications
• 3/16-inch hex socket drive for precise torque application with a standard Allen key
• Partially threaded shank provides a bearing surface for shear loading
• Alloy steel construction meets ASTM A574 mechanical requirements
• Zinc-plated finish offers basic corrosion protection in dry environments

Compatibility

Designed for use in any standard 1/4-20 UNC tapped hole requiring a socket head cap screw per ASME B18.8 dimensional standards.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. De-energize or lock out any equipment before performing fastener work on live machinery per applicable safety procedures. Do not exceed the rated mechanical limits defined by ASTM A574 for this fastener grade.
