Value Collection D30000 Hex Head Cap Screw 1/4-20 X 1/2 in

Product Description

The VALUE COLLECTION D30000 is a fully threaded hex head cap screw designed for general mechanical fastening in trade and industrial applications. Manufactured from Grade 5 steel with a zinc-plated finish, it provides solid tensile strength and basic corrosion resistance suitable for a wide range of structural and equipment assembly tasks. The 1/4-20 unified coarse thread (UNC) pattern and 1/2 inch length under head make this a common-size fastener used across HVAC equipment frames, electrical enclosures, plumbing fixture brackets, and light structural assemblies. This fastener conforms to ASME B18.2.1 dimensional standards. It weighs approximately 0.01 pounds per unit.

This cap screw is well suited for residential and light commercial trade work where a standard UNC hex head fastener is required. Typical applications include securing equipment panels, mounting brackets, junction box covers, and mechanical sub-assemblies where a fully threaded 1/4-20 fastener is specified. HVAC technicians, electricians, plumbers, and general maintenance professionals routinely use this size in equipment service and installation. The zinc plating provides a serviceable corrosion barrier for indoor and protected outdoor environments.

Key Features

• Grade 5 steel construction for reliable tensile and shear strength in mechanical fastening
• Zinc-plated finish for corrosion resistance in typical indoor and sheltered environments
• Fully threaded along the entire shank length for maximum thread engagement
• 1/4-20 UNC thread pattern — one of the most common standard fastener sizes in trade applications
• Conforms to ASME B18.2.1 hex head cap screw dimensional standards
• Minimum order quantity of 50 units supports job-site and shop restocking needs

Compatibility

Designed as a standard UNC hex head cap screw compatible with any 1/4-20 threaded nut, insert, or tapped hole conforming to Unified National Coarse thread specifications.

Installation Notes

Install using a standard hex wrench, socket, or nut driver sized for a 1/4-20 hex head cap screw. Power down or de-energize any electrical or mechanical equipment before accessing fastened panels or enclosures. Do not over-torque zinc-plated fasteners into soft or thin materials, as thread stripping or coating damage may result. Follow applicable equipment manufacturer torque guidelines and relevant code requirements for the trade application.
