Value Collection W57876PS 5/16-18x1 Flat Phillips Screw SS316

Product Description

The VALUE COLLECTION W57876PS is a 5/16-18 x 1 inch flat head Phillips machine screw manufactured from Grade 316 stainless steel with a bright, uncoated finish. It features a unified coarse thread (UNC) pattern and is measured by overall length. Grade 316 stainless offers superior corrosion resistance compared to Grade 304, making it well suited for wet, chemical, or marine environments. The flat head profile sits flush with the mating surface when countersunk, reducing snag points and providing a clean finish on assembled components.

This screw is used in a wide range of light industrial, mechanical, and trade applications where corrosion resistance and a flush-mount fastener are required. Typical installations include HVAC equipment panels, plumbing fixture assemblies, electrical enclosures, pool and spa equipment housings, and similar applications where moisture or chemical exposure is a concern. The Phillips drive is compatible with standard hand and power tools found on most job sites.

Installation Notes

Installation should be performed by a qualified technician using a properly sized Phillips screwdriver or driver bit to avoid cam-out and drive damage. Always verify that the mating hole is correctly countersunk to the appropriate angle to seat the flat head flush. Apply appropriate torque for the fastener diameter and material per relevant mechanical codes or equipment manufacturer guidelines. Power down or de-energize any electrical or mechanical equipment before fastener work begins on live assemblies.
