Value Collection 99057 Hex Cap Screw 3/8-16 X 1-3/4 in Grade 8

Product Description

The VALUE COLLECTION 99057 is a 3/8-16 x 1-3/4 inch hex head cap screw manufactured from Grade 8 steel with an uncoated finish. This fastener features partial threading and conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for high-strength bolted assemblies. Grade 8 steel offers greater tensile and proof load ratings than lower-grade fasteners, suiting it for demanding mechanical and structural connections. The UNC thread form provides broad compatibility with standard tapped holes and nuts. Sold in packages of 100, this screw is commonly specified by maintenance mechanics, millwrights, and general contractors working on equipment, machinery, and structural fabrication.

This hex head cap screw is appropriate for use in mechanical assemblies, structural steel connections, equipment mounting, and general industrial fastening applications where high-strength hardware is required. The partial threading allows the unthreaded shank to act as a bearing surface in clearance holes, which is common in shear-loaded joint designs. Suitable for both shop and field installation across manufacturing, construction, and maintenance trades.

Key Features

• Grade 8 steel construction for high proof load and tensile strength
• 3/8-16 UNC thread form for compatibility with standard nuts and tapped holes
• Partially threaded shank provides a bearing surface in clearance-hole applications
• Uncoated finish — no plating to affect thread fit or dimensional tolerance
• Meets ASME B18.2.1 dimensional standards
• Packaged in quantities of 100 for bench stock and job-lot use

Compatibility

Designed for use with 3/8-16 UNC tapped holes, hex nuts, and threaded inserts conforming to standard inch-series specifications. Suitable for general industrial and structural fastening applications requiring Grade 8 high-strength hardware.

Installation Notes

Installation is performed by maintenance mechanics, millwrights, or general contractors using standard hex wrenches or socket sets. Always ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the joint design engineer or relevant industry standards for Grade 8 fasteners. Do not mix inch-series and metric hardware in the same assembly.
