Value Collection 872299PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 872299PR is a hex socket cap screw designed for fastening applications that require a compact, recessed-drive profile. It features a 3/8-24 UNF thread size with a 2-inch length under head and a 5/16-inch hex drive socket. The screw is partially threaded, meaning the shank is smooth near the head and threaded only toward the tip, which is standard for high-strength clamping applications. Constructed from alloy steel with a zinc-plated finish, it offers solid mechanical strength and basic corrosion resistance. A licensed mechanic, millwright, or maintenance technician typically selects this fastener for precision assemblies.

This screw is suited for general industrial, mechanical, and equipment assembly applications where a flush or low-profile socket cap head is required. The 3/8-24 UNF fine thread pitch provides tighter thread engagement and is commonly specified in applications with thinner materials or where vibration resistance is important. It is sold in a minimum order quantity of 10 pieces per order, with each package containing one screw.

Key Features

• 3/8-24 UNF fine thread for tight thread engagement and vibration resistance
• 2-inch length under head with partial threading for high-strength clamping
• 5/16-inch hex drive socket for standard Allen key or hex bit installation
• Alloy steel construction meets ASME B18.8 and ASTM A574 standards
• Zinc-plated finish provides basic corrosion protection in dry or mildly humid environments

Compatibility

Designed as a standard 3/8-24 UNF hex socket cap screw conforming to ASME B18.8 and ASTM A574, suitable for use in industrial, mechanical, and equipment assembly applications requiring a fine-thread alloy steel fastener.

Installation Notes

Installation requires a 5/16-inch hex key or hex socket bit. Ensure the mating threaded hole is clean and properly tapped to 3/8-24 UNF specification before installation. De-energize or lock out any equipment before accessing fastener locations on live machinery per applicable OSHA lockout/tagout procedures. Do not exceed the torque limits defined by ASTM A574 for this fastener grade and size.
