Value Collection R52001041 Hex Cap Screw 1/4-20 X 8 in

Product Description

The VALUE COLLECTION R52001041 is a 1/4-20 UNC hex head cap screw with an 8-inch length under head. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener is partially threaded and conforms to ASME B18.2.1 and SAE J429 standards. The zinc plating provides basic corrosion resistance for general-purpose indoor and light-duty outdoor applications. At 0.104 pounds per piece, this screw is suited for mechanical assemblies, equipment mounting, and structural connections where a standard-grade inch-series fastener is required. Licensed tradespeople and general contractors will find this a reliable stock fastener for everyday bolted connections.

This hex head cap screw is intended for general mechanical and structural assembly work across residential and light commercial construction, HVAC equipment mounting, plumbing fixture support, and electrical panel or conduit support framing. The 1/4-20 UNC thread form is one of the most common inch-series thread standards in North American trade applications, making this screw compatible with a wide range of standard nuts, inserts, and tapped holes. Partial threading allows the unthreaded shank to bear shear loads in bolted joint applications.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-series hardware
• 8-inch length under head for deep fastening or through-bolting applications
• Grade 2 steel construction meets SAE J429 material requirements
• Zinc-plated finish for basic corrosion protection
• Partially threaded shank provides shear-load bearing capacity at the joint
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed for use with standard 1/4-20 UNC hex nuts, lock nuts, and threaded inserts conforming to inch-series ASME standards. Suitable for general mechanical, structural, and equipment-mounting applications requiring a Grade 2 inch-series hex cap screw.

Installation Notes

Installation is typically performed by general contractors, maintenance technicians, or licensed tradespeople using a standard hex wrench, socket, or adjustable wrench sized for a 7/16-inch hex head. Ensure the mating nut or tapped hole matches the 1/4-20 UNC thread standard before installation. Do not exceed the torque limits appropriate for Grade 2 steel fasteners in the joint design. Inspect the zinc-plated finish for damage before use in corrosion-sensitive environments.
