Results are based on selection by the Editorial Staff. Self-Locking Nylon Screw Bülte GmbH , Ludinghausen, Germany, offers the grub screw 551F for efficient thread security and sealing. Usable in a variety of industries, the advantage of this screw is its self-locking system. There is a nonthreaded section at the top of the screw that works like a lock. When the screw is tightened into the female thread, that thread cuts into the nonthreaded section of the screw effectively locking the threads together preventing loosening. The standard material, polyamide 6.6 natural, is resistant to various chemical products and has very good mechani-cal properties including wear resis-tance, low friction coefficient, high melting point, good impact resistance and light weight.
