standard hardware as listed in the Parts Catalog for the machine involved. DO NOT SUBSTITUTE.
Original equipment standard hardware is defined as Type 8, coarse thread bolts and nuts and thru
hardened flat washers (Rockwell "C" 38-45), all phosphate coated and assembled without
supplemental lubrication (as received) condition. Phosphate coated bolts used in tapped holes in
steel or gray iron, phosphate coated bolts used with phosphate coated prevailing torque nuts (nuts
with distorted threads or plastic inserts), phosphate coated bolts used with copper plated weld nuts.
Markings on bolt heads or nuts indicate material grade ONLY and are NOT to be used to determine
