Value Collection 581468PS Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 581468PS is a hex socket cap screw designed for high-strength fastening in mechanical assemblies, tooling fixtures, and structural joints. This partially threaded fastener uses a 5/16-inch hex drive and features a 3/8-16 UNC thread size with a 1-5/8-inch length under the head. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and a uniform appearance suited for industrial and trade applications. Installation requires a standard hex key or Allen driver. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This screw is appropriate for use in mechanical assemblies, machine frames, jigs, and equipment mounting applications where a recessed drive head and high tensile strength are required. The partial threading allows for precise shoulder-style clamping force in clearance-hole applications. The black oxide coating reduces surface corrosion in moderate-exposure environments. Sold individually, with a minimum order quantity of 10 units per order.

Key Features

• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes
• 1-5/8-inch length under head with partial threading for clamping applications
• 5/16-inch hex socket drive for use with standard Allen keys or hex drivers
• Alloy steel construction provides high tensile strength under load
• Black oxide finish reduces surface corrosion and light-scatter in precision assemblies
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 1-5/8-inch length under head per ASME/ANSI B18.3 specifications.

Installation Notes

Install using a properly sized 5/16-inch hex key or socket driver. Always verify tapped hole thread condition before installation to avoid cross-threading. Ensure mating components are free of debris and burrs before seating the fastener. Follow applicable mechanical assembly standards and torque guidelines for 3/8-16 alloy steel cap screws as specified by the equipment manufacturer or relevant engineering standards.
