The VALUE COLLECTION 204299 is a 5/8-11 x 4 inch hex head cap screw manufactured from Grade 316 stainless steel with a Unified National Coarse (UNC) thread form. Grade 316 stainless steel provides strong resistance to corrosion and chloride exposure, making this fastener a practical choice for demanding environments. The hex drive measures 15/16 inches across flats, compatible with standard hex wrenches and sockets. Length under head is 4 inches with a 5/8-11 thread pitch. This screw is sold individually with a minimum order quantity of 10 pieces, suited for mechanical, structural, and industrial fastening applications installed by maintenance technicians, pipefitters, and millwrights.
This cap screw is appropriate for use in applications where corrosion resistance and strength are required, including marine environments, chemical processing equipment, food service installations, and outdoor structural assemblies. The 316 stainless steel alloy offers improved resistance to pitting compared to 304-series stainless, particularly in salt-spray or acidic conditions. It is well suited for bolted flange connections, equipment mounting, and general mechanical assemblies where a coarse-thread fastener in this size range is specified.
Designed as a standard UNC hex head cap screw in the 5/8-11 thread size, compatible with any application specifying a 5/8-11 coarse thread fastener in 316 stainless steel.
Installation is performed using a 15/16 inch hex wrench, ratchet, or impact driver with the appropriate socket. De-energize or depressurize any system before replacing fasteners on live equipment. Follow applicable mechanical codes and manufacturer torque specifications for the assembly being serviced. Avoid mixing stainless steel fasteners with dissimilar metals in wet environments to minimize galvanic corrosion risk.
