Pull stud or retention knobs are the link to hold the tool holder in the machine spindle. The pulling forces can be quite high, so superior material and hardening is essential for a good quality pull stud.
BPTL provides the pull studs in the standards of BT-MAS-403, DV DIN 69872 and CV-ANSI.
Locknuts are used to fix the tool in the collet of the collet chuck holder. BPTL provides collet chucks in ER, DA and TG collet. Collet chucks are provided in the various tapers such as BT (MAS403/JIS B 6339), DV (DIN 69871), CV (ANSI B5.50/ISO 7388) and HSK (DIN 69893).

Lock nut is sold along with the collet chuck and need not be purchased separately. However, as per customer requirement spare lock nuts are also sold.
