All plow bolts are heat treated to provide a tensile strength of 170,000 p.s.i.
Plow bolts are cold forged by a unique method which provides a fully formed square neck and a raised spherical formed head for greater strength.
All UNC-2A threads have radiused root run-out and blend smoothly into the shank to give added fatigue protection.
Heat treatment is carefully controlled on all earth moving fasteners to provide:
Minimum tensile strength of 170,000 P.S.I. (14% greater than SAE Grade 8.)
Core hardness of Rockwell C36-42.
