Value Collection 837201PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 837201PR is a hex socket cap screw designed for secure fastening in mechanical assemblies, structural connections, and equipment maintenance applications. This screw features a 5/16-18 UNC thread size with a 7/8-inch length under head and is fully threaded along its entire shank. Drive engagement is achieved with a 1/4-inch hex key. Constructed from alloy steel with a zinc-plated finish, it provides solid tensile strength and basic corrosion resistance. The ASTM B695 standard governs the zinc coating, ensuring consistent plating quality. This fastener is sold individually but requires a minimum order quantity of 100 units per order.

This cap screw is suited for general-purpose industrial and mechanical fastening tasks across a wide range of trades, including HVAC equipment assembly, electrical panel work, plumbing fixture mounting, and general maintenance. The 5/16-18 UNC coarse thread pattern is one of the most common unified thread sizes in North American trade work, making this screw a practical stock item for service vans, shops, and job sites. The zinc-plated alloy steel construction is appropriate for dry and mildly humid indoor environments.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded shank provides maximum thread engagement across the 7/8-inch under-head length
• 1/4-inch hex drive accepts standard hex keys and hex bit drivers
• Alloy steel construction offers higher tensile strength than standard carbon steel fasteners
• Zinc-plated finish meets ASTM B695 coating standards for consistent surface protection
• Minimum order quantity of 100 units makes this practical for shop stock and bulk service kits

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any tapped or pre-threaded hole conforming to the unified coarse thread standard for this size.

Installation Notes

Install and remove using a 1/4-inch hex key or matching hex bit driver. Ensure the receiving hole is clean, properly tapped to 5/16-18 UNC, and free of debris before threading. Do not exceed the design load of the tapped material. Follow applicable mechanical and structural codes for the specific application when torque requirements or load ratings are a factor.
