Value Collection 588715PR 5/16-18x1/2 Round Head Phillips Screw

Product Description

The VALUE COLLECTION 588715PR is a 5/16-18 x 1/2 inch round head machine screw designed for general fastening applications across industrial, mechanical, and construction trades. It features a Phillips drive and a zinc-plated steel body that provides corrosion resistance in standard service environments. The screw conforms to ASME B18.6.3 and SAE J82 dimensional and material standards, making it a reliable choice for applications where dimensional consistency and grade compliance matter. The length measurement is taken under the head. No washer is included or integrated.

This screw is suited for light to medium-duty fastening in sheet metal, machinery, enclosures, brackets, and equipment assemblies. The 5/16-18 unified coarse thread engages standard tapped holes and nuts of that specification. The round head profile sits above the work surface and is appropriate where a low-profile flush-mount head is not required. These screws are sold in quantities of 100 per order, making them appropriate for job-lot stocking or production runs.

Key Features

• 5/16-18 unified coarse thread for standard tapped holes and hex nuts
• Round head with Phillips drive for common hand and power tool compatibility
• Steel construction, Material Grade J82, meeting ASME B18.6.3 and SAE J82 standards
• Zinc finish for basic corrosion protection in dry or mildly humid environments
• Length under head: 1/2 inch, measured per standard fastener convention
• No integrated or separate washer

Compatibility

Designed as an OEM-style replacement or general-use fastener for any application requiring a 5/16-18 unified coarse thread, 1/2 inch length under head, round head Phillips machine screw meeting ASME B18.6.3 dimensional standards.

Installation Notes

Installation is performed by general tradespeople, maintenance technicians, or assembly workers using a Phillips screwdriver or a compatible bit driver. Ensure the mating tapped hole or nut is clean and properly threaded to 5/16-18 specification before driving. Do not overtighten, as the zinc coating and J82 grade material have defined torque limits for the thread size. Follow applicable mechanical or equipment manufacturer torque guidance for the specific assembly.
