SAE J429 materail spec or bolt spec
SAE J429 materail spec or bolt spec
(OP)
Does SAE J429 specify a material properties and bolt properties or just bolt properties. (i.e. can I purchase a non threaded SAE J429 rod or would it be a ASTM AXXX steel) I seem to get conflicting responses from coworkers. Any help would be appreciated.
