M6 x 100 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) functions as a precision pin that screws into place through a smaller M5-0.8 thread. The shoulder is ground slightly below nominal so it can slip into a reamed nominal bore and rotate or locate freely.
Cam followers, rollers, and small wheels can run on the shoulder while the threaded end fixes the position. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution.
For metric tooling repairs, Cold Headers can help quote the specified stripper bolt without converting it to an inch size. ISO 7379 catalog nominals often list 6.5 mm here; this stocked 6 mm shoulder is the North American metric tooling variant. Non-catalog metric stripper bolt configurations can be reviewed when the application needs a different shoulder length. 18-8 Stainless Steel Socket Head Stripper Bolts are the stocked routing choice when the print specifies stainless material.
