Value Collection 1436MPR 1/4-20 X 2-1/4 Round Head Phillips Screw

Product Description

The VALUE COLLECTION 1436MPR is a 1/4-20 x 2-1/4 inch round head Phillips drive machine screw manufactured from steel with a zinc-plated finish. Conforming to ASME B18.6.3 and SAE J82 standards, this fastener is built for general-purpose mechanical assembly applications where a low-profile round head and Phillips drive are required. The 1/4-20 thread pitch provides strong clamping force across a wide range of materials. Length is measured under the head. Sold in a minimum order quantity of 100 pieces per order, with one piece per package unit.

This machine screw is suited for light to medium-duty assembly work in commercial, industrial, and residential maintenance settings. Typical applications include equipment fabrication, fixture assembly, panel mounting, and general mechanical repairs where inch-system threaded fasteners are specified. The zinc plating provides basic corrosion resistance suitable for dry and mildly humid indoor environments. Contractors, maintenance technicians, and fabricators working with standard inch-system hardware will find this screw compatible with pre-tapped holes and standard 1/4-20 nuts.

Key Features

• 1/4-20 thread size with 2-1/4 inch length measured under the head
• Round head profile with Phillips drive for high-torque tool compatibility
• Steel construction with zinc-plated finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 fastener standards
• Grade J82 material classification for consistent mechanical properties
• Inch system of measurement; no washer included

Compatibility

Designed for use in standard 1/4-20 tapped holes and with 1/4-20 hex or coupling nuts in inch-system assemblies. Suitable as a direct replacement or stock fastener in general mechanical and equipment assembly applications.

Installation Notes

Installation is typically performed by maintenance technicians, fabricators, or general contractors using a Phillips-head screwdriver or bit driver. Ensure the mating threaded hole or nut is clean and free of debris before driving. Apply appropriate torque for Grade J82 steel fasteners per the assembly specification — do not overtighten, as this can strip threads or shear the fastener. For outdoor or wet environments, consider a higher-grade corrosion-resistant fastener, as zinc plating offers limited protection against prolonged moisture exposure.
