Screw thread engagement
WebbFor the EJOT DEL-TA PT® DS screw special grooves, which help to cut the female thread, are applied to the thread geo-metry of the established DELTA PT®. These groo-ves are especially distinct at the tip of the thread and taper off towards the screw head. This thread forming zone enables a low tightening torque and a high stripping torque.
