Value Collection D30145-3 Hex Head Cap Screw 5/8-11 X 3 in

Product Description

The VALUE COLLECTION D30145-3 is a Grade 5 steel hex head cap screw designed for general-purpose mechanical fastening in industrial, construction, and trade applications. It features a 5/8-11 UNC thread and a 3-inch length under head with partial threading along the shank. The zinc-plated finish provides basic corrosion resistance for use in dry or mildly humid environments. This fastener meets ASME B18.2.1 dimensional standards, making it a reliable choice wherever a standardized inch-series hex cap screw is specified. Typical installers include millwrights, pipefitters, electricians, plumbers, and HVAC technicians working on equipment mounting, structural framing, or mechanical assembly tasks.

This screw is suited for a wide range of residential and commercial trade applications including equipment bases, pipe hangers, structural steel connections, panel mounting, and general mechanical assembly. The partial thread shank provides a grip length that allows the unthreaded section to bear shear loads, making it appropriate for bolted joint applications where full thread engagement is not required or desired. Minimum order quantity is 10 pieces per order.

Key Features

• 5/8-11 UNC thread for standard inch-series fastener compatibility
• 3-inch length under head with partial threading along the shank
• Grade 5 steel construction for medium-strength fastening applications
• Zinc-plated finish for basic corrosion protection in typical indoor environments
• Conforms to ASME B18.2.1 dimensional standard
• Hex head drive for use with standard wrenches and sockets

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application specifying a 5/8-11 UNC partially threaded fastener per ASME B18.2.1.

Installation Notes

Install with a standard hex wrench or socket driver appropriate for a 5/8-inch fastener. Always ensure the mating nut or tapped hole is rated to match the Grade 5 shank load capacity. De-energize, depressurize, or otherwise make the assembly safe before fastener replacement or torquing. Follow the applicable mechanical or structural code for the installation — torque values must be sourced from the engineer of record or equipment manufacturer specifications.
