Each of our bolts is engineered for the correct breaking load for a specific machine size. Our safety bolts or shear bolts have been tensile tested by an independent lab and broke within 3% of the load which is specified by Wohlenberg. While some other venders are selling bolts with one size cross hole for several machine sizes, according to the Wohlenberg machine manual, this is not correct. Each size machine requires a different size cross hole.
