This is a weld in bung for standard 14 TPI Heim Joints. These fit into a 1" tube ID so 1.5"x.25"" or 1.25"x.120"
*Tips to help prevent any seized or warped threads:
Correctly adjust welder settings and start your puddle on the tube. (Too much heat will warp the threads) Do not weld the tube adapter with the rod end threaded inside.
(The two pieces cool at different rates and will lock them together) Wait until everything has completely cooled before threading your rod ends into the adapters
