Step 22Hi-Torque®/Speed Drive Recess
[[br]]Alcoa Fastening Systems' Hi-Torque® recess is milled into the fastener head and has a proven record of performance wherever maximum efficiency from structural fastening systems is required. The system is optimally suited in maintenance efficiency where repeated installation and removal of high strength fasteners are encountered. This cup shaped slot form serves to help the driver to auto-center, which results in timesaving and extra convenience.
During installation or removal, the inverted keystone section of the recess delivers the important locked-in condition. Rotation of the solid driver tip provides a full bearing load, and the interlocked position eliminates the need for end load by the operator. Driver reusability cycle is higher than other fastening systems. The system has sufficient torque reserve for positive and sure removal, even years later.[[br]]
