Value Collection 581522PR Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION 581522PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 7/16-20 UNF thread and measures 1.75 inches under the head with full threading along the entire shank. Driven by a 3/8-inch hex key, it provides reliable torque transfer in confined spaces where a conventional wrench cannot reach. Constructed from alloy steel with a black oxide finish, it offers solid corrosion resistance and surface hardness suited to industrial and maintenance environments. Machinists, millwrights, and maintenance technicians install this fastener across a wide range of precision assemblies.

This cap screw is suited for light industrial, manufacturing, and field maintenance applications where fine-thread UNF fasteners are specified. The 7/16-20 UNF pitch provides finer thread engagement than coarse-thread equivalents, making it appropriate for applications requiring precise clamping load control or installation into tapped holes in harder materials. It is a common choice for fixture plates, machine guards, hydraulic component mounting, and equipment frames. Sold individually with a minimum order quantity of 10 units.

Key Features

• 7/16-20 UNF fully threaded shank for precise clamping in hard-material tapped holes
• 1.75-inch length under head accommodates standard stack-up depths
• 3/8-inch hex drive for use with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide coating provides moderate corrosion resistance and reduces light reflection
• Fully threaded shank eliminates unthreaded grip length, maximizing thread engagement in shallow assemblies

Compatibility

Designed as a standard socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574, suitable for any application specifying a 7/16-20 UNF hex socket cap screw in alloy steel.

Installation Notes

Install using a calibrated 3/8-inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before working on fastened assemblies. Follow the equipment manufacturer's torque specifications and applicable industry standards for final tightening.
