Value Collection R52001116 5/16-18 X 3/4 Flat Head Screw

Product Description

The VALUE COLLECTION R52001116 is a 5/16-18 x 3/4 inch flat head Phillips machine screw manufactured from steel with a zinc-plated finish. It follows the ASME B18.6.3 and SAE J82 standards, confirming dimensional accuracy and consistent thread form. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it well suited for applications where a low-profile fastener is required. This screw is a standard inch-series fastener used by maintenance technicians, fabricators, and general tradespeople across a wide range of assembly and equipment service tasks. The zinc plating provides a basic level of corrosion resistance for indoor and light-duty applications.

This machine screw is appropriate for use in light to medium-duty mechanical assemblies, panel mounting, equipment enclosures, and general maintenance applications. The 5/16-18 UNC thread is a coarse-thread designation common in steel fabrication and mechanical assemblies. The Phillips drive accepts standard Phillips screwdrivers and power bits. This fastener is sold in a minimum order quantity of 50 pieces per order, supplied as a quantity of 1 package.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes

Compatibility

Designed as a standard inch-series UNC machine screw for use in any tapped or pre-threaded hole sized for 5/16-18 thread, including steel, aluminum, and plastic components in general mechanical and maintenance applications.

Installation Notes

Install using a Phillips screwdriver or Phillips power bit sized for the fastener head. Countersink the mating surface to the correct angle to achieve a flush seating of the flat head. Do not overtighten — follow the torque requirements specified by the equipment manufacturer or applicable assembly standard. Ensure the receiving thread is clean and free of debris before installation.
