They have a raised countersunk head with a square neck to prevent them from rotating during tensioning.
Ajax plow bolts are forged from alloy steels and heat-treated to the specifications of the original equipment manufacturers.
The minimum tensile strength is 170,000 lbf/in2.
Impact resistance is greatly improved by tempering and fatigue resistance reduced by having rolled threads.
Plow bolts are made only in inch-series with UNRC threads and are secured with hexagon plow nuts.
