Value Collection 588753PR 5/16-18x4 Round Head Phillips Screw

Product Description

The VALUE COLLECTION 588753PR is a 5/16-18 x 4 inch round head Phillips machine screw manufactured from steel with a zinc finish. It meets ASME B18.6.3 and SAE J82 standards, making it a reliable choice for general-purpose fastening applications in light industrial, mechanical, and assembly work. The round head profile provides a low-clearance, finished appearance above the mating surface. The Phillips drive allows for quick installation with standard hand tools or power drivers. Length is measured under the head. This screw is sold individually but must be ordered in multiples of 10.

This screw is suited for use in general mechanical assembly, equipment fabrication, and light structural fastening where a 5/16-18 unified coarse thread is specified. It is appropriate for use in applications that do not require a washer face or washer under the head. Electricians, millwrights, plumbers, and general maintenance technicians commonly use this fastener size in panel mounting, bracket attachment, and equipment assembly tasks. Always verify thread engagement depth and mating material before selecting fastener length.

Key Features

• 5/16-18 unified coarse thread for broad compatibility with standard tapped holes and nuts
• 4 inch length measured under the head for accurate installation planning
• Round head profile with Phillips drive for use with standard bits and power drivers
• Steel construction with zinc finish for corrosion resistance in dry indoor environments
• Meets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical consistency
• No washer face — designed for applications where a flat bearing surface is sufficient

Compatibility

Designed for use in any application requiring a 5/16-18 unified coarse thread machine screw with a round head Phillips drive in the inch measurement system.

Installation Notes

Install using a Phillips screwdriver or Phillips-tip power driver of the appropriate size to avoid cam-out and head damage. Ensure the mating hole is properly tapped to 5/16-18 UNC before driving. Do not overtighten — follow the torque requirements of the assembly design. For outdoor or high-moisture environments, evaluate whether the zinc finish provides sufficient corrosion protection for the application.
