Value Collection 99216 Hex Head Cap Screw Grade 8 Steel

Product Description

The VALUE COLLECTION 99216 is a fully threaded hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with no coating, this screw measures 1-8 inch thread size with a 2-inch length under the head. The UNC (Unified National Coarse) thread standard ensures broad compatibility with standard tapped holes and nuts. Grade 8 steel provides significantly higher tensile and proof-load ratings compared to lower-grade fasteners, making this screw appropriate for structural, mechanical, and heavy-equipment assemblies. Installation is performed by mechanics, millwrights, and maintenance technicians using standard hex wrenches or socket sets.

This cap screw is suited for general industrial, mechanical, and structural applications where high-strength steel fasteners are required. The fully threaded design maximizes thread engagement along the entire shank, which is advantageous in through-bolt configurations or wherever extended thread engagement is needed. Typical use cases include machine frames, equipment brackets, structural steel connections, and heavy-duty mechanical assemblies. Sold in packages of 10, this screw is appropriate for both single repairs and small-batch production or maintenance work.

Key Features

• Grade 8 steel construction delivers high tensile strength for demanding fastening applications
• Fully threaded shank maximizes thread engagement over the full 2-inch length
• UNC thread standard ensures compatibility with standard coarse-thread tapped holes and nuts
• Uncoated finish suits applications where coating is not required or will be applied separately
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Sold in a package of 10 for efficient stocking and job-lot use

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any UNC-tapped hole or hex nut in the 1-8 thread size, conforming to ASME B18.2.1 dimensional requirements.

Installation Notes

Install using a properly sized hex socket or open-end wrench to avoid rounding the hex head. Ensure the mating tapped hole or nut is the correct UNC thread specification before installation. Always verify that Grade 8 fasteners are appropriate for the joint design and load requirements of the application. De-energize or lock out any equipment before performing fastener service on mechanical assemblies per applicable safety procedures.
