Value Collection 837213PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 837213PR is a hex socket cap screw designed for fastening applications that require a recessed drive and a secure, high-strength connection. Manufactured from alloy steel with a zinc-plated finish, this screw features a 5/16-18 UNC thread size and measures 2.25 inches in length under the head. It is partially threaded and driven with a 1/4-inch hex key. The zinc plating provides corrosion resistance suitable for general industrial and mechanical assemblies. This fastener meets ASTM B695 standards and is installed by mechanics, maintenance technicians, pipefitters, and other trade professionals working on equipment requiring precision fastening.

This screw is used across a wide range of applications including HVAC equipment assembly, mechanical enclosures, pump and motor mounting, and general-purpose industrial fabrication. Its 5/16-18 UNC coarse thread and partial threading make it well suited for clamping through clearance holes into threaded bores in metal components. It is appropriate for both light commercial and residential equipment maintenance and repair scenarios where a clean hex socket drive is required for torque-critical or space-restricted installations.

Key Features

• 5/16-18 UNC coarse thread for reliable engagement in standard tapped holes
• 2.25-inch length under head accommodates moderate material stack heights
• Partial threading allows clamping force at the shank before thread engagement
• 1/4-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Zinc-plated finish meets ASTM B695 and offers corrosion resistance in dry to mildly humid environments

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 5/16-18 UNC hex socket cap screw with a 2.25-inch length under head and a 1/4-inch hex drive.

Installation Notes

Installation requires a 1/4-inch hex key or Allen bit driver. Ensure the mating threaded bore is clean and free of debris before driving the screw. Power down any equipment fully before accessing fastener locations on live mechanical or electrical assemblies. Do not exceed the rated torque range for 5/16-18 alloy steel fasteners as specified by applicable equipment service documentation.
