Value Collection R52001074 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION R52001074 is a 1/4-20 flat head Phillips machine screw designed for general mechanical assembly and fastening applications. This screw is manufactured from steel with a zinc-plated finish for basic corrosion resistance. It measures 2.75 inches in overall length and uses a 1/4-20 unified coarse thread pitch. The flat head profile allows the fastener to sit flush with or below the mating surface when installed in a countersunk hole. Conforming to ASME B18.6.3 and SAE J82 standards, this screw is suited for professional and industrial fastening work where dimensional consistency and material grade are required.

This screw is used in light industrial, mechanical, and equipment assembly applications where a flush-mount fastener is needed. The 1/4-20 thread size is one of the most common unified coarse thread specifications, making it widely applicable across machine frames, enclosures, panels, and fabricated assemblies. It is intended for installation in pre-tapped or threaded holes and is compatible with standard Phillips No. 2 drive bits and screwdrivers. This item is sold individually but requires a minimum order quantity of 100 pieces per order.

Compatibility

Designed as a standard 1/4-20 flat head Phillips machine screw conforming to ASME B18.6.3 and SAE J82, suitable for use in any application requiring a unified coarse thread fastener of this size and head style.

Installation Notes

Install in a properly sized and tapped 1/4-20 threaded hole or use with a matching hex nut. For flush seating, the receiving material should be countersunk to the appropriate angle for a flat head screw. Use a No. 2 Phillips screwdriver or bit and apply consistent torque to avoid cam-out or thread damage. Ensure the mating surface or thread is free of debris before installation.
