Value Collection 97164 Hex Head Cap Screw 5/8-11 X 9 in Grade 5

Product Description

The VALUE COLLECTION 97164 is a partially threaded hex head cap screw designed for heavy-duty mechanical and structural fastening applications. Manufactured from Grade 5 steel with no finish coating, this fastener meets ASME B18.2.1 and SAE J429 standards for dimensional and strength requirements. The 5/8-11 UNC thread form and 9-inch length under head make it well suited for through-bolt applications in thick assemblies, frames, and equipment bases. Installation is performed with standard hex wrenches or impact drivers sized for 5/8-inch fasteners. Partial threading provides a smooth shank section for shear-load bearing in close-tolerance through-holes.

This cap screw is used across industrial maintenance, mechanical equipment assembly, structural fabrication, and general trade service work wherever a heavy hex fastener with a long grip length is required. The uncoated finish is suitable for interior or protected installations where corrosion exposure is limited. Tradespeople in HVAC equipment rigging, plumbing equipment mounting, and electrical enclosure framing commonly use fasteners of this type when securing base frames, brackets, and support structures to walls, pads, or equipment bases.

Key Features

• 5/8-11 UNC thread size for high-load fastening in steel assemblies
• 9-inch length under head accommodates thick stack-ups and long through-bolt applications
• Grade 5 steel construction meets SAE J429 minimum tensile strength requirements
• Partially threaded shank provides a smooth bearing surface for shear loads
• Uncoated finish maintains dimensional consistency for close-tolerance fits
• Conforms to ASME B18.2.1 for hex cap screw dimensional standards

Compatibility

Designed as an OEM-style replacement or general-service hex head cap screw for use in standard 5/8-11 UNC tapped holes and through-bolt applications in mechanical, structural, and equipment-mounting assemblies.

Installation Notes

Installation should be performed by qualified tradespeople using appropriately sized hex wrenches, ratchets, or impact drivers rated for 5/8-inch fasteners. Always verify thread engagement depth and hole alignment before torquing. Follow applicable mechanical or structural codes for proper torque values based on joint type and load requirements. Inspect mating threads for damage or contamination before installation to avoid galling or cross-threading.
