The VALUE COLLECTION R63033243 is a hex head cap screw designed for fastening applications that require corrosion resistance and reliable clamping strength. It features a 5/8-11 UNC thread pattern and measures 1 inch under the head. Constructed from Grade 316 stainless steel, this fastener resists corrosion in wet, chemical-exposed, and marine environments. The 15/16-inch hex head accepts standard hex wrenches and sockets. It is sold individually and is appropriate for use by maintenance technicians, pipefitters, plumbers, and mechanical contractors working with corrosion-resistant assemblies.
This cap screw is suited for residential and commercial installations where standard carbon steel fasteners are not appropriate due to moisture, salt, or chemical exposure. Typical applications include pipe flange connections, equipment mounting, pump housings, and general mechanical assemblies. Its UNC thread form ensures compatibility with standard inch-series tapped holes and nuts in that thread class.
Designed as a standard inch-series hex head cap screw for use with 5/8-11 UNC tapped holes, nuts, and hardware in corrosion-resistant fastening assemblies.
Installation is performed by maintenance technicians, pipefitters, or mechanical contractors using standard hex wrenches or socket sets. Ensure the mating tapped hole or nut matches the 5/8-11 UNC thread specification before installation. De-energize and depressurize any system before replacing or installing fasteners on live equipment. Follow applicable mechanical and plumbing codes for fastener torque requirements specific to the assembly being serviced.
