Value Collection 97199 Hex Head Cap Screw 7/8-9 Grade 5

Product Description

The VALUE COLLECTION 97199 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. It features a 7/8-9 UNC thread size and a 3-1/4 inch length under head, manufactured from Grade 5 steel in an uncoated finish. This fastener meets ASME B18.2.1 and SAE J429 standards, making it a recognized choice for industrial, equipment, and fabrication work where dimensional and strength consistency are required. Installation is typically performed by millwrights, maintenance mechanics, or general contractors using standard hex drive tooling.

This cap screw is suited for medium-strength bolted joint assemblies in industrial machinery, structural steel connections, agricultural equipment, and general manufacturing applications. The partial thread design provides a smooth shank section that resists shear loading and maintains clamping force across joint interfaces. Sold in a package quantity of 25, it fits procurement needs for shop floor stock, MRO inventory, or project-specific hardware requirements.

Key Features

• 7/8-9 UNC thread — compatible with standard inch-series nuts and tapped holes
• Partially threaded shank for improved shear resistance in bolted joints
• Grade 5 steel construction meets SAE J429 minimum proof load and tensile strength requirements
• Uncoated finish suitable for use as-is or for field application of thread-locking compounds or coatings
• Conforms to ASME B18.2.1 for hex head cap screw dimensions and tolerances
• Package quantity of 25 per unit for efficient stocking and procurement

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 7/8-9 UNC thread pattern and a 3-1/4 inch length under head fastener meeting ASME B18.2.1 and SAE J429 specifications.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople following applicable torque specifications from the equipment manufacturer or relevant engineering standards. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Apply thread lubricant or fastener compound only if specified by the joint design. Always use properly rated tooling matched to the 7/8 hex drive size to avoid fastener damage.
