Hexagonal nut STMxxD-B series

threadedprecisionfor collets

Concentricity and repeatability extremely high due to the fact that the thread and taper are ground in one operation Application for all collet chucks, collet holders and acceptances DIN 6499/ISO 15488 (ER/ESX) Remark other executions, e.g. Clamping Nuts with External Thread (also for Sealing Discs HPDI), are available on request Execution with EasyClick and hexagon head (form D) case-hardened (660 HV10) and burnished since January 2007 all new series of clamping nuts with remark EasyClick are manufactured in this execution offers better balance compensation for higher speed and an optical engaging feature Special features all collets with outside form DIN 6499/ISO 15488 can be clamped also available in type B Execution type B – for tools, which have to be clamped with increased clamping force more tenacious and harder because of a special heat treatment unchanged mass, protection against corrosion and lower friction are additional advantages compared to the standard execution the low friction takes effect in the thread as well as at the 30° cone of the collet and results in an approx. 50% higher clamping force type B nuts are not recommend for high precision applications
