The snap ring is a simple and quick method to connect the thrust pad to the tommy screw. Instead of DIN 6311 a thrust pad GN 6311.1 can be used. In that case the tommy screw and the thrust pad have to be ordered separately. The movable bar of the tommy screw is held in any position by the pres- sure spring. The end caps are pressed on to the bar and thus limit the bar travel, they can also be supplied separately should the bar be plated first. The official DIN standard sheets provides for steel rings at this point. see also... • Thrust Pads GN 6311.1 → Page 1069 Information DIN 6306 Tommy Screws Extract with Movable Bar 1 d 1 2 l 1 3 Type How to order 1 2 3 DIN6306-M12-50-D 3 Type D Without thrust pad E With thrust pad DIN 6311 • Steel Property class 5.8 - - Blackened - - Thrust point hardened • Bar end caps Plastic, gray • Thrust Pads DIN 6311 → Page 1066 • ISO Fundamental Tolerances → Page 2151 • Strength Values of Screws → Page 2152 • RoHS Specification
