Value Collection KP44052 3/8-16 X 4 in Grade 8 Hex Cap Screw 25pk

Product Description

The VALUE COLLECTION KP44052 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications in mechanical, structural, and equipment assembly work. Measuring 3/8-16 thread size with a 4-inch length under head, this partially threaded fastener uses Unified National Coarse (UNC) thread form and meets ASTM A354 BD specification. The zinc-plated finish provides baseline corrosion resistance for general indoor and light outdoor use. Sold in a package of 25, this screw is suited for maintenance technicians, millwrights, and tradespeople who need a reliable, high-tensile fastener for demanding bolted connections.

Grade 8 hex head cap screws are commonly used in heavy equipment repair, HVAC unit mounting, electrical enclosure assembly, pump and motor mounting, and structural steel connections. The partial threading provides full grip in the clamped material while the unthreaded shank handles shear loads. The 3/8-16 UNC thread pattern is one of the most widely specified inch-series fastener sizes in industrial and commercial trade work, compatible with standard 3/8-16 hex nuts and threaded inserts.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high-tensile strength applications
• 3/8-16 UNC thread for broad compatibility with standard nuts and tapped holes
• 4-inch length under head with partial threading to handle both tension and shear loads
• Zinc-plated finish for corrosion resistance in general service environments
• Package of 25 units reduces per-fastener cost on larger jobs

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, washers, and tapped components in inch-series fastener applications across mechanical, HVAC, plumbing, and electrical trade installations.

Installation Notes

Installation should be performed by qualified tradespeople familiar with torque requirements for Grade 8 fasteners at 3/8-16 thread size. Use a calibrated torque wrench and follow the applicable equipment manufacturer specifications for final torque values. Ensure mating threads are clean and free of debris before assembly. Avoid mixing inch-series and metric hardware, and inspect fasteners for thread damage before use.
