Value Collection 97200 Hex Head Cap Screw 7/8-9 X 3.5 in Grade 5

Product Description

The VALUE COLLECTION 97200 is a hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 5 steel in an uncoated finish, this fastener features a 7/8-9 thread size with a 3.5-inch length measured under the head. The partial threading design provides clamping strength suited to bolted joint assemblies where a smooth shank is required between mating surfaces. Compliance with ASME B18.2.1 ensures dimensional consistency for high-volume or precision assembly work. Sold in a package quantity of 25, this screw is a practical choice for maintenance shops, contractors, and fabricators working with standard inch-series fastener specifications.

This cap screw is suited for structural and mechanical assemblies that call for a Unified National Coarse (UNC) thread form in inch-series sizing. Typical applications include equipment fabrication, machinery maintenance, and structural steel connections where Grade 5 tensile strength and ASME-compliant geometry are required. The hex head drives with standard 6-point sockets or wrenches, making it accessible across a wide range of service environments from field repairs to shop assembly lines.

Key Features

• Grade 5 steel construction meets standard minimum tensile strength requirements for medium-strength fastener applications
• Partially threaded shank provides a smooth bearing surface between clamped components
• 7/8-9 UNC thread form is compatible with standard inch-series tapped holes and nuts
• ASME B18.2.1 compliance ensures dimensional accuracy and interchangeability
• Uncoated finish suitable for use as-is or for post-installation coating or plating
• Package quantity of 25 supports both single-use repair and small-batch production needs

Compatibility

Designed as an OEM-style replacement or standard fastener for any assembly requiring a 7/8-9 UNC hex head cap screw with a 3.5-inch length under head, Grade 5 steel, and ASME B18.2.1 compliance.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or structural assemblers using standard 6-point sockets or open-end wrenches sized for a 7/8-9 hex head. Depower or de-energize equipment before accessing fastener locations on live machinery. Do not reuse fasteners that show thread damage, corrosion, or deformation. Torque to the value specified by the equipment manufacturer or applicable structural design standard for Grade 5 fasteners in the relevant joint configuration.
