Value Collection D30062 Hex Head Cap Screw 3/8-16 X 3 in

Product Description

The VALUE COLLECTION D30062 is a 3/8-16 hex head cap screw designed for general mechanical fastening in trade and industrial applications. The screw measures 3 inches under the head with a Unified National Coarse (UNC) thread pitch, conforming to ASME B18.2.1 dimensional standards. Constructed from Grade 5 steel with a zinc-plated finish, it offers a reliable combination of tensile strength and corrosion resistance suited for moderate-duty structural and mechanical assembly work. The partial threading along the shank allows for secure clamping force in bolted joint applications. This fastener is typically installed by mechanics, millwrights, HVAC technicians, and general trades during equipment assembly or field repair.

This cap screw is appropriate for use in residential and light commercial mechanical systems where 3/8-16 UNC threaded fasteners are specified. Common applications include equipment mounting, bracket installation, and mechanical assembly tasks where a hex-drive fastener with a zinc coating is required for mild corrosion resistance. It is sold with a minimum order quantity of 10 pieces and packaged individually per unit.

Key Features

• 3/8-16 UNC thread — widely compatible with standard tapped holes and hex nuts in trade applications
• 3-inch length under head with partial threading for controlled clamping in bolted joints
• Grade 5 steel construction provides higher tensile strength than Grade 2 fasteners
• Zinc-plated finish offers basic corrosion resistance for indoor and protected outdoor use
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment and interchangeability

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw for use anywhere ASME B18.2.1-compliant inch-series fasteners are specified in mechanical, HVAC, or structural assembly applications.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 3/8-16 cap screw head. Always verify the mating threaded hole or nut is also rated for 3/8-16 UNC before installation. Power down or de-energize any equipment before replacing or installing fasteners on electrical or mechanical assemblies. Do not exceed the rated load for Grade 5 fasteners — consult equipment manufacturer documentation for torque requirements specific to the assembly.
