Value Collection R52001144 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION R52001144 is a 5/16-18 flat head Phillips machine screw used for general mechanical fastening in trade and industrial applications. Made from steel with a zinc plating finish, it meets ASME B18.6.3 and SAE J82 standards for dimensional and material grade compliance. The 3-inch overall length and 5/16-18 unified coarse thread make it suitable for a wide range of metal-to-metal and metal-to-panel fastening tasks. The flat head profile sits flush with or below the surface of the mating material when installed into a countersunk hole. Licensed tradespeople and maintenance technicians working in mechanical, electrical, or HVAC enclosure applications will encounter this fastener type regularly.

This screw is commonly used in light fabrication, equipment assembly, panel mounting, and repair work across residential and commercial trade settings. It is appropriate for applications where a flush or countersunk fastener is required and where a Phillips drive is preferred for speed with standard screwdrivers or power tools. The zinc plating provides basic corrosion resistance suitable for indoor or protected environments. Sold individually with a minimum order quantity of 10 units.

Key Features

Compatibility

Designed as a standard 5/16-18 flat head Phillips machine screw for use in any application requiring ASME B18.6.3 or SAE J82 compliant fasteners with a countersunk head style.

Installation Notes

Installation is performed by general maintenance technicians, millwrights, or licensed tradespeople depending on the application. Ensure the mating hole is properly tapped to 5/16-18 and countersunk to the appropriate angle before driving the screw. Use a correctly sized Phillips bit to avoid cam-out and fastener head damage. Do not exceed the rated material capacity of the mating substrate when torquing.
