* Ultimate load is 5 times the Working Load Limit. Individually proof tested to 2 1/2 times the Working Load Limit.
** The tightening torque values shown are based upon threads being clean, dry and free of lubrication.
§ Long bolts are designed to be used with soft metal (i.e., aluminum) work piece. While the long bolts may also be used with ferrous metal (i.e., steel & iron) work pieces, short bolts are designed for ferrous work pieces only.
§§ Bolt specification is a Grade 8 Alloy socket head cap screw to ASTM A-574. All threads are UNC - 3A.
