The nut is tilted over the threaded spindle. When in position, the nut is brought into a straight position for mating of the two threads on the nut and spindle. The nut will then have to be turned only by a fraction of a rotation to achieve clamping. Functional safety exists only if the clamping surface lies at a right angle to the threaded bolt. see also... • Quick Release Star Knobs GN 6336.3 How to order (Steel) 1 GN 6303.1-M8 How to order (Stainless steel) 1 2 GN 6303.1-M12-NI 2 | 2.2 Tensioning, Clamping with Knobs 1 Thread d1 1 Thread d1 2 Material www.jwwinco.com | phone: 1-800-877-8351
