Compatibility
This kit shares the 7/16-20 thread and .685 in. length of ALL16170 but uses a larger 5/8 in. head instead of the standard head size. Confirm head clearance before substituting for ALL16170 in applications where head diameter matters. It is not interchangeable with the M11-1.50 metric thread kits (ALL16176, ALL16177), the longer 1.00 in. kit (ALL16173), or the shorter .500 in. kit (ALL16178).
