Overview

 
 

Supported Types

A low-profile head with super high-strength recess offers elegance and functionality.

Low Profile Head

The Mortorq® Super high-strength spiral drive system is today's most advanced industrial drive system in automotive/transportation manufacturing. Featuring an exceptionally shallow recess, it sets the standard for strength and functionality. Its recess geometry provides complete 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, Mortorq Super contributes to greener automotive products.

Minimum Ultimate Torque

Bit strength is an essential parameter in the design of internally driven fasteners. It's the starting point for determining the appropriate fastener diameter, head style, and size and indicates the type of material to be used.

Increased recess removal wall contact area provides higher removal torque capabilities for service environment conditions where corrosion or galling affects the removal of screws.

Coatings in the drive recess can cause improper or misaligned bit engagement. With added clearance between the bit and recess, Mortorq Super Spiral Drive System provides added robustness in the handling and assembly of screws.

Contact Drive SurfaceThe table above shows that the drive contact surface area increases while the head height decreases. Savings result in less materials usage in the screw and mating components around tightly packed subassemblies. Removal torque capability is increased due to an even larger removal wall surface area in contact with the driver bit.
