Nuts

Has greater surface area than NM-series nuts, making wrenching easier.
Deisgned to be used with cap screws which have a minimum tensile strength not greater than 90,000 pcs.
Used in bridge and building construction, material handling, heavy equipment and field machinery.
Steel nylon insert stop nuts are less expensive than grade-C automation lock nuts.
Nylon insert locknuts are not designed to be used in temperatures over 250 degrees fahrenheit
