The VALUE COLLECTION 204336 is a hex head cap screw designed for general fastening applications in corrosive or moisture-prone environments. Manufactured from Grade 316 stainless steel, this fastener offers superior resistance to chlorides, salt water, and chemical exposure compared to standard 304-grade hardware. The screw measures 5/16-18 thread size with a 1-1/2 inch length under head and follows the UNC (Unified National Coarse) thread standard. The 1/2 inch hex drive allows installation with standard hex wrenches or sockets. Installers working on HVAC, plumbing, pool equipment, or marine-adjacent mechanical assemblies will find this fastener suited for applications where long-term corrosion resistance is required.
This screw is commonly used in light mechanical assemblies, equipment mounting, and structural fastening where exposure to moisture, chemicals, or outdoor conditions demands a corrosion-resistant grade. Grade 316 stainless steel is a common specification for pool equipment installations, coastal HVAC units, chemical handling systems, and any application where standard carbon steel fasteners would corrode prematurely. The UNC thread form is compatible with the widest range of standard threaded holes and nuts in inch-based mechanical systems.
Designed for use in any application requiring a 5/16-18 UNC inch-standard hex head cap screw in Grade 316 stainless steel. Suitable for mechanical assemblies, equipment frames, and mounting hardware where corrosion-resistant fasteners are specified.
Install using a 1/2 inch open-end wrench, box wrench, or socket driver. Power down or depressurize any equipment before fastening into live mechanical assemblies. Do not mix Grade 316 stainless steel fasteners with dissimilar metals in high-conductivity environments without appropriate isolation to prevent galvanic corrosion. Follow applicable mechanical codes for torque and fastener specifications relevant to the assembly being serviced.
