Value Collection 3114MPF 5/16-18 Machine Screw Flat Phillips

Product Description

The VALUE COLLECTION 3114MPF is a 5/16-18 unified coarse thread machine screw with a flat head and Phillips drive, manufactured from steel with a zinc finish. It measures 7/8 inches in overall length and is built to ASME B18.6.3 and SAE J82 standards, making it suitable for general-purpose mechanical assembly work. The zinc coating provides basic corrosion resistance for indoor and light-duty applications. This fastener is installed by maintenance technicians, millwrights, and general tradespeople wherever a countersunk flat-head screw is specified in a threaded hole or clearance application.

This screw is used in a wide range of light-to-medium industrial, commercial, and mechanical assembly applications where a flush-mount fastener is needed. The flat head profile allows the screw to sit flush with or below the surface of the mating material, which is important in panel assemblies, equipment housings, and structural brackets. The 5/16-18 thread size is a common inch-series coarse thread found across HVAC equipment, electrical enclosures, plumbing fixtures, and general machinery. Sold in multiples of 100 units per order.

Compatibility

Designed as a general-purpose inch-series machine screw for use in any application requiring a 5/16-18 coarse thread flat head Phillips fastener per ASME B18.6.3.

Installation Notes

Install using a Phillips screwdriver or appropriate Phillips bit with a power driver set to a controlled torque to avoid stripping the drive recess. Ensure the receiving hole is properly tapped or threaded to 5/16-18 specifications before fastening. For countersunk applications, verify the mating material is chamfered to match the flat head angle. Always power down or de-energize any equipment before accessing fastened panels or enclosures.
