... technologies for a reliable hold Threaded insert self-tapping / with hexagonal socket Hexagonal socket The threaded insert Ensat®-SI with cutting slot is a self-tapping fastener for the creation ofwear-free, vibration resistant screw joints with high loading capacity in materials with low shearing strength. The Ensat® is inserted via the hexagonal socket, permitting theachievement of short installation time. Other benefits: More simple driving tools and machines which require only clockwise rotation. The Ensat® can be extracted without problems before the recycliug process.
