Value Collection 99197 Hex Head Cap Screw 7/8-9 Grade 8 25 Pack

Product Description

The VALUE COLLECTION 99197 is a partially threaded hex head cap screw designed for heavy-duty fastening applications where high tensile strength is required. Manufactured from Grade 8 steel with an uncoated finish, this fastener measures 7/8-9 thread size with a 2.5-inch length under head. The UNC thread form and ASME B18.2.1 and SAE J429 compliance make it a reliable choice for structural and mechanical assemblies. This package contains 25 screws, suited for contractors, maintenance technicians, and tradespeople who need a dependable bulk supply of high-strength fasteners.

This screw is commonly used in industrial maintenance, heavy equipment assembly, structural steel connections, and general mechanical installations where Grade 8 strength is specified. The partially threaded shank provides a smooth bearing surface through thick materials before the thread engages, which is preferred in applications requiring precise clamping force. Suitable for use in both shop and field environments by mechanics, millwrights, and maintenance professionals working to ASME and SAE fastener standards.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using the appropriate hex drive socket or wrench sized to the fastener head. Always ensure mating threads and bearing surfaces are clean and free of debris before assembly. Follow applicable torque specifications from your engineering drawings or fastener standards documentation, as torque values are application-specific and not provided here. Power down or de-energize any equipment before replacing structural fasteners in service.
