The GIBRALTAR 40508G is an equal double threaded stud with a 3/8-16 thread size and a 5-inch overall length. Manufactured from alloy steel with a black oxide finish, this stud provides corrosion resistance and durability in demanding fastening applications. The Grade 5 material rating and Class 50 thread fit classification indicate consistent dimensional accuracy and reliable load-bearing performance. A flat is included for wrench engagement during installation. This fastener is typically installed by licensed mechanics, millwrights, plumbers, or HVAC technicians in structural and mechanical assemblies requiring a double-end threaded connection point.
Equal double threaded studs like the 40508G are used in a wide range of mechanical and trade applications including pump mounting, manifold assemblies, flange connections, equipment brackets, and general fabrication work. The equal thread configuration means both ends carry the same 3/8-16 thread, making it suitable for through-bolt or stud-mount applications where nuts are applied to both ends. This stud fits residential and light commercial mechanical systems as well as industrial equipment installations.
Designed as a standard 3/8-16 equal double threaded stud for use in mechanical assemblies, equipment mounting, and structural fastening applications where a Grade 5 alloy steel stud is specified.
Installation of threaded studs should be performed by qualified mechanics or trade professionals following applicable mechanical codes and equipment manufacturer specifications. Always ensure mating components are properly aligned before threading on nuts to avoid cross-threading or galling. Apply thread lubricant or anti-seize compound as appropriate for the application environment. De-energize or depressurize any connected system before performing fastener work on live equipment.
