Value Collection 30067 Hex Cap Screw 3/8-16 X 4-1/2 in Grade 5 25 Pk

Product Description

The VALUE COLLECTION 30067 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers solid tensile strength and basic corrosion resistance in dry to mildly humid environments. The 3/8-16 UNC thread pattern and 4-1/2 inch length under head make it suitable for medium-duty clamping and assembly work across a range of trade applications. Sold in a package of 25, this fastener meets ASME B18.2.1 dimensional standards, ensuring consistent head geometry and thread tolerances for reliable installation with standard tooling.

This hex head cap screw is used in HVAC equipment assembly, electrical panel and enclosure mounting, plumbing fixture support brackets, and general structural fastening where a partially threaded grip is required. The partial thread allows the unthreaded shank to bear shear loads, making it a common choice when joining multiple members where thread engagement is needed only at the nut end. It is appropriate for residential and light commercial trade installations where inch-series UNC fasteners are specified.

Key Features

• 3/8-16 UNC thread — standard inch-series coarse thread for broad hardware compatibility
• 4-1/2 inch length under head — suits medium-depth through-bolt and stud applications
• Partially threaded shank — improves shear strength and allows precise clamping
• Grade 5 steel construction — meets minimum proof load and tensile strength requirements for medium-duty fastening
• Zinc-plated finish — provides basic corrosion resistance in indoor and low-moisture environments
• Conforms to ASME B18.2.1 — consistent dimensional tolerances for hex head geometry and thread form
• Sold in a pack of 25 — suitable for single-job use or low-volume stock replenishment

Compatibility

Designed as a standard inch-series hex head cap screw for use wherever a 3/8-16 UNC partially threaded fastener meeting ASME B18.2.1 is required.

Installation Notes

Install with a standard 9/16 inch hex wrench or socket driver. Ensure mating threads are clean and free of debris before installation. For structural or load-bearing assemblies, consult applicable building or mechanical codes for required fastener grade and torque specifications. Always de-energize equipment before fastening work on electrical or HVAC components.
