Value Collection D30058 Hex Head Cap Screw 3/8-16 X 2 in

Product Description

The VALUE COLLECTION D30058 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. It features a 3/8-16 UNC thread with a 2-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. This fastener meets ASME B18.2.1 dimensional standards, making it a reliable choice for engineers, maintenance technicians, and trade professionals who require consistent, spec-compliant hardware for assemblies, equipment mounting, and structural connections.

This hex head cap screw is suited for a wide range of industrial, mechanical, and trade applications where a partially threaded fastener is required to allow for clamping force or joint movement between mating components. Common uses include equipment assembly, HVAC unit mounting brackets, electrical panel hardware, plumbing fixture supports, and general mechanical maintenance. The zinc plating provides a baseline level of corrosion protection appropriate for indoor and light-duty outdoor environments.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard inch-system hardware
• 2-inch length under head for applications requiring fastener reach with a clamping zone
• Partially threaded shank allows for controlled clamping without thread engagement through the full joint
• Grade 5 steel construction meets medium-strength fastener requirements
• Zinc-plated finish provides corrosion resistance for general service environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 3/8-16 UNC threaded application requiring a partially threaded fastener per ASME B18.2.1 specifications.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 3/8-16 fastener. Always ensure mating threads are clean and free of debris before installation. De-energize any electrical systems and shut off mechanical equipment before accessing fastener locations in live assemblies. Do not exceed the torque capacity appropriate for Grade 5 steel hardware as specified in the relevant mechanical or structural code for your application.
