Value Collection 581515PR Hex Socket Cap Screw 7/16-14 Unc

Product Description

The VALUE COLLECTION 581515PR is a hex socket cap screw designed for high-strength mechanical fastening in industrial, maintenance, and fabrication applications. This fastener features a 7/16-14 UNC thread size and measures 5.5 inches in length under the head with partial threading. The 3/8-inch hex drive socket head provides a secure engagement point for Allen keys and hex bit drivers. Constructed from alloy steel with a black oxide coating, it delivers solid tensile strength and moderate corrosion resistance in controlled environments. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for precision assembly work.

This cap screw is suited for use in machinery, fixtures, tooling, and structural assemblies where a recessed drive and high clamping load are required. The partial threading is typical for applications that demand clamping force between joined materials rather than full thread engagement through a through-hole. It is commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors in both light and heavy industrial settings.

Key Features

• 7/16-14 UNC thread size for standard unified coarse thread engagement
• 5.5 inches length under head with partial threading for clamping applications
• 3/8-inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide coating provides a clean finish with mild corrosion resistance
• Conforms to ASME/ANSI B18.3 socket cap screw dimensional standards

Compatibility

Designed as a standard-geometry replacement or new-installation hex socket cap screw for machinery, fixtures, and structural assemblies requiring a 7/16-14 UNC partially threaded fastener with a 3/8-inch hex drive.

Installation Notes

Installation is performed using a 3/8-inch hex key or socket bit driver. Ensure mating threads are clean and free of debris before driving the fastener. Follow applicable torque specifications from your assembly drawings or engineering standards for ASTM A574 alloy steel cap screws. Do not substitute thread lubricants or anti-seize compounds unless specified by the equipment manufacturer, as this affects clamp load calculations.
