Value Collection C703606 Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION C703606 is a 7/8-9 hex head cap screw designed for high-strength fastening in demanding mechanical and structural applications. Manufactured from Grade 8 steel with a bright, uncoated finish, this screw delivers reliable tensile strength where critical joint integrity is required. The partially threaded shank provides a bearing surface under the head, making it well suited for applications where clamp load distribution matters. At 2.25 inches in length under the head, this fastener conforms to ASME B18.2.1 and SAE J429 standards. Licensed tradespeople, maintenance mechanics, and millwrights working on heavy equipment, structural assemblies, or industrial machinery routinely specify Grade 8 hardware for its elevated proof load and tensile strength ratings.

This cap screw is used across a wide range of industrial, commercial, and trade applications where high-strength inch-series fasteners are specified. Typical installations include heavy equipment frames, mechanical assemblies, steel structural connections, and machinery mounts. The 7/8-9 UNC thread pattern is a common inch-series size found in agricultural equipment, construction machinery, and industrial fabrication environments. Sold in a package quantity of ten, this screw is suitable for both maintenance stock and project-specific procurement.

Compatibility

Designed as a standard inch-series Grade 8 hex head cap screw for use with 7/8-9 UNC tapped holes and compatible hex nuts in mechanical and structural assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener procedures. Always degrease mating threads and consult the applicable torque specification table for Grade 8 fasteners before tightening. Use a calibrated torque wrench to achieve proper clamp load. Do not substitute Grade 8 fasteners with lower-grade hardware in structural or safety-critical joints.
