Value Collection 203124 Hex Cap Screw 5/16-18 X 2 in 316 Ss

Product Description

The VALUE COLLECTION 203124 is a fully threaded hex head cap screw designed for fastening applications that require corrosion resistance and mechanical strength. Built from Grade 316 stainless steel with a bright, uncoated finish, this screw uses a 5/16-18 UNC thread form and measures 2 inches under the head. Grade 316 stainless offers superior resistance to chlorides and harsh environments compared to Grade 304, making it a reliable choice where moisture, chemicals, or marine exposure are factors. Installation is straightforward using standard hex tooling.

This fastener is suited for use in plumbing, HVAC, pool and spa equipment, and general industrial or marine applications where corrosion-resistant hardware is required. The UNC thread standard ensures broad compatibility with standard tapped holes and nuts in inch-measurement assemblies. It is commonly specified by plumbers, HVAC technicians, pool service professionals, and maintenance mechanics working in corrosive or wet environments.

Key Features

• Grade 316 stainless steel construction for strong resistance to corrosion and chloride exposure
• Fully threaded along the 2-inch shank for maximum thread engagement
• 5/16-18 UNC thread form for compatibility with standard inch-measurement tapped holes and nuts
• Bright, uncoated finish with no plating that could flake or delaminate
• Hex head drive accepts standard hex wrenches and sockets

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 5/16-18 UNC fully threaded fastener in Grade 316 stainless steel.

Installation Notes

Install using an appropriately sized hex wrench or socket driver. Ensure the mating tapped hole or nut is also rated for the load and environment before installation. When working on pressurized systems, depressurize and power down equipment before replacing fasteners. Avoid mixing stainless steel fasteners with dissimilar metals in highly conductive or submerged environments to minimize galvanic corrosion risk.
