The MORTORQ® SUPER Spiral Drive System is the most advanced industrial drive system available today. Featuring an exceptionally shallow recess, it sets the standard for strength and functionality. Its recess geometry provides full driver contact over the entire mating surface of the recess wings. This results in extreme high-torquing capability without risk of damage to the fastener or surrounding head area. Minimal head height reduces the weight of fastened components. Made with less material and light in weight.
