Torx 6-Lobe Flat Head Machine Screws are used because of the unconventional and efficient drive style. The Torx 6 Lobe drive style is designed so that the driver will not slip out of the fastener recess during installation, since the driver is not inherently centered on the fastener. This creates a lesser chance of screw stripping as well as allowing for a higher torque installation.
Stainless Steel Torx Machine Screws feature a countersunk flat head and are made of industry standard grade 18-8 Stainless Steel. 18-8 Stainless is rust and corrosion resistant in applications exposed to fresh water moisture making screws in this material suitable for long lasting applications.
