Value Collection R52001147 Pan Head Machine Screw 5/16-18

Product Description

The VALUE COLLECTION R52001147 is a 5/16-18 x 3.5-inch pan head Phillips drive machine screw manufactured from steel with a zinc-plated finish. Built to ASME B18.6.3 and SAE J82 standards, this fastener delivers consistent thread engagement and corrosion resistance suitable for general mechanical assemblies. The pan head profile provides a low-profile bearing surface with ample drive recess depth for positive Phillips bit engagement. Length is measured under the head. Installers and maintenance techs working in light industrial, commercial, or equipment service applications will find this a dependable stock fastener for standard 5/16-18 threaded hardware.

This machine screw is suited for use in metal-to-metal fastening applications where a 5/16-18 unified coarse thread is required. It fits standard 5/16-18 tapped holes or hex nuts and is appropriate for equipment assembly, panel mounting, brackets, and structural fastening in both indoor and protected outdoor environments. The zinc-plated finish provides moderate corrosion protection for general-purpose use. Sold individually per package; minimum order quantity is 10 units.
