Value Collection R52001110 Machine Screw 5/16-18 X 1/2 in

Product Description

The VALUE COLLECTION R52001110 is a 5/16-18 x 1/2 inch pan head Phillips machine screw manufactured from steel with a zinc-plated finish. It meets ASME B18.6.3 and SAE J82 standards, making it a reliable fastener for general mechanical assembly work. The pan head profile provides a low-profile bearing surface with a wide underhead contact area. Length is measured under the head at 1/2 inch. This screw is suited for use by maintenance technicians, equipment assemblers, and trade professionals requiring a standardized inch-series fastener in mild corrosive environments.

This fastener is appropriate for light-duty to medium-duty mechanical assemblies in residential, commercial, and light industrial settings. Pan head Phillips drive screws of this size are commonly used in electrical enclosures, HVAC equipment panels, plumbing fixture brackets, and general sheet metal or tapped-hole applications. The zinc coating provides basic corrosion resistance suitable for indoor and sheltered outdoor use. Sold in quantities that support production and service work requiring consistent, standards-compliant hardware.

Installation Notes

Install using a Phillips screwdriver or Phillips bit rated for the fastener drive size. De-energize and lock out any electrical equipment before fastening hardware on or near energized panels. Do not overtighten into tapped holes in soft materials such as aluminum or plastic, as thread stripping may occur. Follow applicable equipment manufacturer torque guidance where specified.
