Value Collection 97188 Hex Cap Screw 3/4-10 X 8 in Grade 5

Product Description

The VALUE COLLECTION 97188 is a 3/4-10 partially threaded hex head cap screw manufactured from Grade 5 steel with an uncoated finish. It measures 8 inches under the head and follows a Unified National Coarse (UNC) thread form. Conforming to ASME B18.2.1, this fastener is built for structural and mechanical assemblies that require a reliable bolted joint. Licensed tradespeople, maintenance technicians, and mechanical contractors reach for Grade 5 hex cap screws when standard hardware-grade fasteners are not adequate but high-alloy bolting is not required.

This screw is suited for general industrial, commercial construction, and mechanical assembly applications. Partial threading makes it well suited for joints where a grip length is needed — the unthreaded shank bears the shear load while the threads engage the nut or tapped hole. It is commonly installed in equipment mounting, structural steel connections, HVAC equipment bases, pump skids, and similar applications requiring a medium-strength, inch-series fastener.

Key Features

• 3/4-10 UNC thread for broad compatibility with standard inch-series nuts and tapped holes
• 8-inch length under head provides extended grip length for thick stack-ups or deep clearance holes
• Grade 5 steel meets medium-strength requirements per ASME B18.2.1
• Partially threaded shank carries shear loads and reduces thread-galling risk in through-bolt applications
• Uncoated finish — suitable for use with field-applied coatings or in interior dry environments
• Sold in packages of 10, with a minimum order quantity of 1

Compatibility

Designed for use with standard 3/4-10 UNC inch-series hex nuts, flat washers, and lock washers in structural and mechanical bolted connections per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with proper torque procedures for Grade 5 fasteners. Always power down or de-energize equipment before fastener replacement on live systems. Use a properly sized hex wrench or impact socket rated for 3/4-inch drive to avoid fastener or tool damage. Inspect mating threads and seating surfaces for damage or contamination before installation.
