Value Collection 97201 Hex Head Cap Screw 7/8-9 X 4 in Grade 5

Product Description

The VALUE COLLECTION 97201 is a 7/8-9 hex head cap screw designed for structural and mechanical fastening applications requiring reliable clamping force. Manufactured from Grade 5 steel with no finish coating, this fastener measures 4 inches under the head and features partial threading along the shank. The Unified National Coarse (UNC) thread form and ASME B18.2.1 compliance make it a standard-dimension fastener suited for use with matching Grade 5 or compatible nuts and tapped holes. It is installed by millwrights, maintenance mechanics, pipefitters, and general tradespeople wherever a heavy-hex-pattern fastener is required.

This screw is appropriate for general industrial, mechanical, and structural assembly work where inch-series UNC hardware is specified. The 7/8-9 thread designation and 4-inch under-head length suit it for medium-to-heavy-duty bolted connections in equipment frames, supports, flanges, and machinery bases. The uncoated finish is typical for indoor or protected installations or where a field-applied coating will be used. Sold in packages of 25 units.

Key Features

• Grade 5 steel construction for elevated tensile and proof load requirements versus Grade 2
• Partial threading along the shank provides a smooth grip section for shear-load applications
• UNC thread form (7/8-9) compatible with standard inch-series nuts and tapped components
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Uncoated finish suitable for dry or protected environments or field-applied coating
• Packaged in quantities of 25 for jobsite or shop use

Compatibility

Designed as an ASME B18.2.1 inch-series hex head cap screw for use with standard 7/8-9 UNC nuts, washers, and tapped holes in mechanical and structural assemblies.

Installation Notes

Installation is performed by qualified mechanics or tradespeople using standard hex or socket wrenches sized for the 7/8-inch hex head. Apply a fastener-grade lubricant or thread compound as required by the application specification before torquing. Follow applicable industry or equipment manufacturer torque specifications for Grade 5 hardware at this diameter and thread pitch. Inspect threads on both the fastener and mating component for damage or contamination before assembly.
