Value Collection MP99106 Hex Head Cap Screw 1/2-13 Grade 8

Product Description

The VALUE COLLECTION MP99106 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assembly work. Sized at 1/2-13 UNC thread with a 1-1/2 inch length under head, this fastener is manufactured from Grade 8 steel with a bright uncoated finish. Grade 8 classification indicates a high-tensile fastener suitable for demanding load-bearing connections. Sold in a package quantity of 25, this screw conforms to ASME B18.2.1 and SAE J429 standards, making it appropriate for applications where dimensional and strength traceability is required.

This hex head cap screw is used across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture support structures, electrical enclosure assembly, and general mechanical fabrication. The 1/2-13 UNC thread size is one of the most common inch-series coarse thread fasteners in use, and the fully threaded shank makes it well suited for through-hole clamping and short-grip installations. Tradespeople and fabricators working with steel structures, equipment bases, and bracket assemblies will find this screw a standard fit for everyday fastening tasks.

Installation Notes

Installation is performed with a standard 3/4-inch hex wrench or socket driver. Ensure mating threads are clean and free of debris before installation. Grade 8 fasteners should not be substituted with lower-grade hardware in load-bearing or torque-critical joints. Follow applicable structural or equipment manufacturer specifications when determining installation torque for the given joint material and application.
