Value Collection D30145-23/4 Hex Cap Screw 5/8-11 X 2-3/4 in

Product Description

The VALUE COLLECTION D30145-23/4 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. Built to Grade 5 steel with a zinc-plated finish, this fastener meets ASME B18.2.1 standards and provides reliable clamping strength in moderate-load assemblies. The 5/8-11 UNC thread and 2-3/4 inch length under head make it a common choice for equipment mounting, frame assembly, and mechanical connections found in HVAC, plumbing, and light industrial installations. Licensed tradespeople and maintenance technicians reach for this fastener when a proven, code-recognized hex cap screw is needed on the job.

This hex head cap screw is suited for use in residential and commercial mechanical system installations where UNC inch-series fasteners are specified. Typical applications include mounting HVAC equipment frames, securing pipe hangers, anchoring electrical enclosures, and general structural assembly. The partial threading allows the unthreaded shank to bear shear loads at joint interfaces, making it appropriate for connections that require accurate alignment before clamping.

Key Features

• Grade 5 steel construction provides tensile strength appropriate for moderate structural and mechanical fastening
• Zinc-plated finish offers corrosion resistance for indoor and light-exposure applications
• Partial threading allows the shank to carry shear loads and aid in part alignment
• 5/8-11 UNC thread is a standard inch-series coarse thread widely compatible with nuts and tapped holes
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Hex drive head accepts standard combination wrenches and impact 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

Installation is typically performed by licensed mechanical, HVAC, or plumbing technicians using standard combination wrenches or impact tools sized for a 5/8 inch hex fastener. Always de-energize and lock out equipment before fastening or removing hardware on mechanical systems. Verify that mating threads and tapped holes are clean and free of debris before installation. Follow applicable torque requirements specified by the equipment manufacturer or relevant code for the assembly type.
