Value Collection MP30005 Hex Head Cap Screw 1/4-20 X 1-1/4 in

Product Description

The VALUE COLLECTION MP30005 is a 1/4-20 hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, it provides solid corrosion resistance for indoor and light outdoor use. The partially threaded shank follows the UNC thread standard and conforms to ASME B18.2.1 dimensional requirements. Length under head is 1-1/4 inches with a 1/4-20 thread size. Each package contains 50 screws. This fastener is installed by maintenance technicians, millwrights, HVAC mechanics, plumbers, and electricians wherever a reliable, standardized inch-series hex cap screw is needed.

This screw is suited for residential and commercial equipment assembly, panel mounting, bracket fastening, and general mechanical connections. The partially threaded shank allows for clamping force between mating components when the unthreaded portion spans the joint. Typical applications include equipment frames, junction box mounting, ductwork support hardware, and similar light-to-medium structural connections. The zinc coating resists surface oxidation in dry or mildly humid environments.

Key Features

• Grade 5 steel construction for reliable tensile strength in standard fastening applications
• Zinc-plated finish provides corrosion resistance in dry and low-humidity environments
• Partially threaded shank conforms to ASME B18.2.1 for dimensional consistency
• UNC 1/4-20 thread standard for broad compatibility with inch-series hardware
• 1/4-20 x 1-1/4 inch size is one of the most common fastener sizes in trade work
• Sold in a 50-piece package to support job-lot quantities

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw compatible with any 1/4-20 UNC tapped hole or nut requiring a partially threaded Grade 5 fastener.

Installation Notes

Install with a standard hex wrench or socket drive sized for a 1/4-20 hex head cap screw. Ensure mating threads are clean and free of debris before installation. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific application. Do not use in applications requiring a higher-grade fastener without verifying load requirements.
