Value Collection MP30009 Hex Head Cap Screw 1/4-20 X 2-1/4 in 50pk

Product Description

The VALUE COLLECTION MP30009 is a 1/4-20 UNC hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. Measuring 2-1/4 inches under the head, this fastener is partially threaded and conforms to ASME B18.2.1 dimensional standards. It is sold in a package quantity of 50. Grade 5 steel provides a reliable combination of tensile strength and toughness suited to general mechanical and structural assembly. The zinc plating offers baseline corrosion resistance in typical indoor and light-duty outdoor environments. HVAC technicians, plumbers, electricians, and general maintenance trades reach for this size fastener regularly in equipment mounting, bracket installation, and panel assembly work.

This screw is appropriate for a wide range of light industrial, commercial, and residential trade applications. Common uses include securing equipment mounting brackets, attaching flanges, fastening sheet metal frames, and assembling structural components where a standard 1/4-20 UNC thread form is specified. Partial threading provides a smooth shank section that improves shear resistance and allows proper clamping on through-bolted assemblies. The hex drive is compatible with standard 7/16-inch hex tooling.

Installation Notes

Install using a 7/16-inch open-end, box-end, or socket wrench. Ensure mating tapped holes or nuts match the 1/4-20 UNC thread standard before driving. Do not overtorque, as Grade 5 fasteners have defined proof load limits. Always de-energize and isolate equipment per applicable codes before performing any fastener work on live assemblies.
