Value Collection C703165 Hex Head Cap Screw 7/16-20 Grade 8

Product Description

The VALUE COLLECTION C703165 is a Grade 8 steel hex head cap screw designed for high-strength fastening in demanding mechanical and structural assemblies. The screw features a 7/16-20 thread size (UNF) and measures 2-1/4 inches under the head. It is partially threaded and carries an uncoated, bright finish. Grade 8 steel provides higher tensile strength than Grade 5 or Grade 2 fasteners, making it suitable for heavy-duty bolted joints subject to significant static or dynamic loads. These screws conform to ASME B18.2.1 and SAE J429, the standard specifications governing inch-series hex head cap screws.

This screw is used in a wide range of industrial, mechanical, and maintenance applications where a high-strength UNF fastener is required. Typical uses include equipment assembly, machinery mounting, structural connections, and heavy fabrication work. The 7/16-20 UNF thread offers finer thread engagement than UNC equivalents, which improves load distribution and resistance to loosening under vibration. This listing is sold in a package quantity of 50 pieces, suited to shop stock and field inventory needs. Installation is performed by mechanical contractors, maintenance technicians, and fabricators working in commercial and industrial environments.

Key Features

• 2-1/4 inches length under head, partially threaded shank
• Bright uncoated finish; suitable for use with standard hardware finishes or field coating
• Conforms to ASME B18.2.1 and SAE J429 standards
• Package quantity of 50 pieces for shop or field stocking

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 7/16-20 UNF threaded holes and nuts in general mechanical and structural assemblies per ASME B18.2.1.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance personnel using a standard hex wrench or impact driver with the appropriate socket. Always verify thread engagement and hole condition before fastening. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 8 fasteners of this diameter and thread pitch. Follow applicable codes and safety procedures when working on pressurized, rotating, or load-bearing assemblies.
