Value Collection 2-HF-31C-600 Hex Cap Screw 5/16-18 X 6 in

Product Description

The VALUE COLLECTION 2-HF-31C-600 is a fully threaded hex head cap screw designed for industrial and trade fastening applications requiring corrosion-resistant hardware. Built from Grade 316 stainless steel with a bright, uncoated finish, this screw delivers reliable performance in wet, chemical, or marine environments where standard carbon steel fasteners are not suitable. The 5/16-18 UNC thread pattern and 6-inch length under head make it a practical choice for through-bolting thick assemblies, brackets, or structural components where full thread engagement along the entire shank is required.

This fastener is well suited for use in plumbing, HVAC, pool, and marine service work where Grade 316 stainless is specified for its superior chloride and corrosion resistance compared to Grade 304. Typical applications include securing equipment mounts, pump flanges, pool equipment enclosures, and pipe hangers in humid or chemically aggressive environments. The fully threaded design provides maximum thread engagement across varying material thicknesses without the need for a separate nut seated against an unthreaded shank.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• Fully threaded shank along the full 6-inch length under head for maximum thread engagement
• 5/16-18 UNC thread standard for compatibility with standard inch-system nuts and tapped holes
• Bright, uncoated finish — no plating that can chip or delaminate in harsh conditions
• Hex head drive for installation with standard hex wrenches or sockets

Compatibility

Designed for use with standard 5/16-18 UNC hex nuts, washers, and tapped holes in inch-measurement fastening applications across HVAC, plumbing, pool, and general industrial service work.

Installation Notes

Install using an appropriately sized hex wrench or socket driver. Power down or depressurize any equipment before replacing fasteners on live systems. When torquing stainless steel fasteners, use anti-seize compound to prevent galling, which is common with stainless-on-stainless contact. Follow applicable mechanical codes and equipment manufacturer specifications for required fastener torque values.
