Value Collection MP39067 3/8-16 X 4-1/2 in Grade 8 Cap Screw

Product Description

The Value Collection MP39067 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications. It measures 3/8-16 thread size with a 4-1/2 inch length under head, partially threaded along the shank. The Zinc Yellow Dichromate finish provides corrosion resistance in demanding service environments. This fastener meets ASME B18.2.1 standards and uses a Unified National Coarse (UNC) thread form. It is suitable for mechanical assemblies, equipment mounting, and structural connections where a high-strength, partially threaded fastener is required. Licensed tradespeople and maintenance technicians across HVAC, plumbing, and industrial service sectors regularly use Grade 8 hardware in critical joint applications.

The MP39067 is appropriate for use in bolted connections requiring controlled clamping loads and shank bearing strength. The partial threading allows the unthreaded shank to bear shear loads while the threaded portion engages the nut or tapped hole. This makes it a common choice for through-bolted equipment frames, machine bases, and bracket assemblies in both residential and light commercial service settings. Sold in a package quantity of 10.

Installation Notes

Install using an appropriate hex wrench or socket driver. Always match the fastener grade to the joint design requirements and use a properly rated nut or tapped hole with a 3/8-16 UNC thread. Ensure mating surfaces are clean and free of debris before assembly. Follow applicable mechanical or structural codes for torque and joint requirements.
