Value Collection 39245 Hex Head Cap Screw Grade 8 Steel

Product Description

The VALUE COLLECTION 39245 is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to standard hardware-grade bolts. The screw measures 1-1/4-7 thread size with a 5-1/2 inch length under head and conforms to ASME B18.2.1 dimensional standards. The partial threading is intentional, providing a smooth shank section for applications where shear loads are a primary concern. Mechanical contractors, millwrights, and maintenance technicians working on heavy equipment or structural connections will find this fastener suited to demanding service conditions.

This cap screw is appropriate for use in heavy-duty mechanical assemblies, industrial equipment mounting, and structural connections where Grade 8 tensile ratings are specified. The UNC thread form is the standard for inch-series fasteners in North American trade applications. The zinc yellow dichromate finish provides a base level of corrosion protection suitable for indoor and controlled-environment installations. Sold in a package quantity of 2 per order.

• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application specifying a 1-1/4-7 UNC Grade 8 partially threaded fastener per ASME B18.2.1.

Installation Notes

Installation of Grade 8 fasteners should be performed by qualified mechanical or structural trades familiar with proper torque specifications for the application and joint design. Always verify thread engagement depth and mating nut or tapped hole grade before installation. Use appropriate hand tools or calibrated torque wrenches as required by the applicable design specification. Do not mix inch-series and metric fasteners in the same joint.
