Value Collection 99225 Hex Head Cap Screw Grade 8 Steel

Product Description

The VALUE COLLECTION 99225 is a hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Manufactured from Grade 8 steel with no additional coating, this screw measures 1-8 inch thread size with a 6-inch length under head. The partially threaded shank provides a grip area that resists joint movement under load. It conforms to ASME B18.2.1 standards, making it a recognized choice for applications where dimensional consistency and material performance are required. Machinists, millwrights, maintenance technicians, and field mechanics commonly install this class of fastener across a wide range of equipment and structural connections.

This screw is suited for heavy-duty bolted connections in industrial equipment, machinery frames, structural steel, and mechanical assemblies where a Grade 8 strength rating is specified. The UNC thread standard ensures broad compatibility with standard inch-series nuts and tapped holes. The uncoated finish is typical for applications where the fastener will be field-treated, used in controlled environments, or where a coating is not required by the assembly specification. Sold in a package quantity of 10.

Compatibility

Designed for use with standard inch-series UNC hex nuts and tapped holes requiring a 1-8 thread size in applications specifying Grade 8 fastener strength.

Installation Notes

Installation should be performed by qualified mechanical, structural, or maintenance personnel following applicable codes and assembly specifications. Always verify thread engagement depth and joint requirements before installation. Use a calibrated torque wrench and apply the torque value specified by the equipment manufacturer or structural engineer for Grade 8 fasteners of this size. De-energize and lock out any equipment before accessing fastened assemblies on live machinery.
