Value Collection 592301PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 592301PR is a hex socket cap screw designed for secure, high-torque fastening in structural and mechanical assemblies. It features a 5/16-18 UNC thread size with a 5-inch length under the head and is partially threaded, allowing for controlled clamping force across unthreaded shank sections. The drive is a 1/4-inch internal hex socket, requiring an Allen key or hex bit driver for installation. Constructed from 18-8 austenitic stainless steel, it offers corrosion resistance suitable for exposed or wet environments. This fastener meets ASME/ANSI B18.3 and ASTM F837 standards, making it appropriate for precision mechanical, industrial, and maintenance applications.

This screw is used in a wide range of trade and industrial settings where a flush or low-profile fastener head with high clamp load is required. Typical applications include equipment mounting, bracket attachment, machine assembly, and structural connections where corrosion resistance is a priority. The partially threaded design is particularly useful when clamping two components together without threading both parts, ensuring a solid bearing surface on the unthreaded shank. Sold individually per package with a minimum order quantity of 10 units.

Key Features

• 5/16-18 UNC thread size for standard inch-series fastening applications
• 5-inch length under head provides extended grip range for thicker assemblies
• Partially threaded shank delivers accurate clamping without over-threading
• 1/4-inch hex socket drive for use with Allen keys or hex bit drivers
• 18-8 austenitic stainless steel (Material Grade A2) for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw suitable for use in any application requiring an ASME/ANSI B18.3 compliant inch-series socket head cap fastener in stainless steel.

Installation Notes

Installation is performed using a 1/4-inch hex key or hex socket bit driver. Always ensure the mating threaded hole is clean and free of debris before driving the fastener. Apply thread lubricant or anti-seize compound as appropriate for the application environment, particularly in stainless-to-stainless contact to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly.
