Value Collection -97193-1 Hex Cap Screw 7/8-9 X 1-3/4 Gr5

Product Description

The VALUE COLLECTION -97193-1 is a fully threaded hex head cap screw designed for general mechanical and structural fastening applications. It features a 7/8-9 UNC thread and a 1-3/4 inch length under head, manufactured from Grade 5 steel with no additional finish coating. Grade 5 steel offers a balance of strength and machinability suitable for a wide range of assembly and maintenance tasks. This fastener conforms to ASME B18.2.1, the standard governing inch-series hex cap screws, ensuring dimensional consistency across the head geometry, thread form, and body tolerances. It is a standard stock item used by millwrights, maintenance mechanics, pipefitters, and general contractors.

This hex cap screw is suited for residential and commercial construction, industrial equipment assembly, and field repair applications where a coarse-thread UNC fastener is specified. The fully threaded configuration is ideal for through-bolt applications and short-grip joints where thread engagement over the full shank length is required. Pack quantity is 25 units per package, making it appropriate for job-lot purchases or stocking a service van.

Key Features

• 7/8-9 UNC coarse thread for high thread engagement and vibration resistance
• 1-3/4 inch length under head for through-bolt and short-grip applications
• Fully threaded shank provides maximum thread engagement in thinner material stacks
• Grade 5 steel construction meets medium-strength fastener requirements per SAE specifications
• Uncoated finish — suitable for use as-is or with field-applied corrosion protection
• Conforms to ASME B18.2.1 for dimensional compliance

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with any application specifying a 7/8-9 x 1-3/4 inch fully threaded Grade 5 fastener per ASME B18.2.1.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or general tradespeople using a standard hex wrench, socket, or open-end wrench sized for a 7/8-9 hex cap screw. Always verify the mating thread is clean and free of debris before installation. Torque to the value specified by the equipment manufacturer or applicable structural code for Grade 5 fasteners in the joint material. Do not use an uncoated fastener in an environment requiring corrosion resistance without applying an appropriate protective coating or sealant.
