Value Collection 99106 Hex Head Cap Screw 1/2-13 X 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION 99106 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Manufactured from Grade 8 steel with no finish coating, this fastener meets the dimensional and mechanical requirements of ASME B18.2.1 and SAE J429. The 1/2-13 UNC thread and 1-1/2 inch length under head make it a common choice in heavy-duty bolted joints where elevated tensile strength and precise thread engagement are required. Sold in a pack of 50, it suits both job-site use and shop stock for maintenance and repair work.

This cap screw is suited for use in industrial machinery, agricultural equipment, structural steel connections, and general mechanical assemblies where Grade 8 strength is specified. The UNC thread form is standard across American inch-series fastener applications, making this screw compatible with the widest range of tapped holes and standard hex nuts in that size class. Technicians, millwrights, and maintenance mechanics commonly specify Grade 8 hardware for high-load or vibration-prone connections.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• Fully threaded along the entire 1-1/2 inch shank length under head
• 1/2-13 UNC thread form compatible with standard American inch-series nuts and tapped holes
• Uncoated finish — suitable for applications where plating or coating is not required or will be field-applied
• Conforms to ASME B18.2.1 dimensional standards and SAE J429 mechanical property specifications
• Pack of 50 for stocking, service fleets, and multi-fastener jobs

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, lock nuts, and tapped holes per inch-series fastener specifications. Suitable as a direct replacement in any application calling for a Grade 8, 1/2-13 x 1-1/2 inch fully threaded hex head cap screw per ASME B18.2.1 or SAE J429.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or journeymen in the applicable trade. Always verify the required torque specification from the equipment manufacturer or applicable structural standard before tightening — do not estimate torque values from general references alone. Inspect mating threads for damage or contamination before assembly. Grade 8 fasteners must not be substituted with lower-grade hardware in safety-critical or load-bearing joints.
