Class 12.9 EXTREME STRENGTH 12-Point Flange Bolts are a great alternative to hex head bolts. With a non-serrated, smooth-bottom flange and a reduced outer flange diameter, these bolts are easy to install in tight spaces or bored holes.
Greater torque can be applied to these bolts because of the 12-spline design, providing more contact area while tightening.
Pair with locking or non-locking Class 12 nuts and extreme strength lock washers such as Nord-Lock.
