The VALUE COLLECTION R80064421 is a fully threaded hex head cap screw sized 3/8-24 x 1 inch, manufactured from Grade 316 stainless steel with no coating applied. The 3/8-24 designation indicates a 3/8-inch nominal diameter with a 24-thread-per-inch Unified Fine (UNF) pitch. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, making this fastener a practical choice for wet, chemical, or marine environments. The uncoated finish preserves the native material properties and eliminates coating thickness variation at mating surfaces. Licensed tradespeople and maintenance professionals use this fastener across mechanical, plumbing, and equipment-assembly applications where corrosion resistance is a primary requirement.
This hex head cap screw is suited for residential and commercial applications where stainless steel fasteners are specified. Common installation scenarios include pipe flange assembly, equipment mounting in corrosive or washdown environments, pool and spa mechanical enclosures, and marine or coastal HVAC equipment. The UNF thread form is standard in precision and higher-stress assemblies where finer thread engagement is preferred over coarse-thread alternatives. The fully threaded shank provides maximum thread engagement across the full 1-inch length under the head.
Designed as a standard 3/8-24 UNF hex head cap screw suitable for use in any application calling for a fully threaded, Grade 316 stainless steel fastener of this thread size and length.
Installation is performed by mechanical, plumbing, or HVAC technicians depending on the application. Use a properly sized hex wrench or socket to avoid rounding the head. Ensure mating threads are clean and free of debris before installation. When used in flanged or gasketed connections, follow the equipment manufacturer's torque sequence; no torque value is specified for this fastener in the available data.
