Value Collection 99007 1/4-20 X 1-3/4 in Grade 8 Hex Cap Screw

Product Description

The VALUE COLLECTION 99007 is a 1/4-20 hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from Grade 8 steel with no additional finish coating, this screw delivers high tensile strength suitable for demanding bolted joint assemblies. The partially threaded shank follows UNC thread form and conforms to ASME B18.2.1 dimensional standards. Length under head measures 1-3/4 inches. Each package contains 100 screws, making it a practical quantity for production, maintenance, and repair work.

This fastener is appropriate for use in machinery, equipment fabrication, industrial assemblies, and general trade applications where a high-strength inch-series cap screw is required. The 1/4-20 UNC thread is one of the most common fastener sizes in the field and fits standard hex nuts, lock nuts, and threaded inserts of the same thread specification. The partially threaded configuration provides a bearing shank section, which is useful when clamping unthreaded material between the fastener head and nut.

Key Features

• 1/4-20 UNC thread form, partially threaded shank
• 1-3/4 inch length under head per ASME B18.2.1
• Uncoated finish — no plating or treatment that could affect thread fit or dimensional tolerances
• Sold in a 100-piece package for shop and field inventory
• Conforms to ASME B18.2.1 dimensional standard

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1/4-20 UNC threaded nuts, inserts, and tapped holes in conformance with ASME B18.2.1.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or general tradespeople using a standard hex wrench or socket set sized for the fastener head. Ensure mating threads are clean and free of debris before installation. Grade 8 fasteners should not be substituted with lower-grade hardware in safety-critical or load-bearing applications. Follow applicable torque guidelines from the joint design specification or relevant industry standards for the assembly being serviced.
