    Due to the high amount of friction between the pin and collar, this fastener requires a hex key ( Allen wrench ) to prevent the pin from rotating as the collar is torqued down around the pin.
  • Bolted joints
    … still easily that could [8.27] and table 8.7 8.25 screws of the strength class 10.9 until dimension M10 still with box wrenches according to DIN 838 and screws until dimension M6 with Allen wrenches after DIN 911 on … However, obtained attracting torques and therewith also prestressing forces according to Abb. are subjected to 8.25 … The bearing without objective torque control secretes therefore for highly stressed bolted joints as suitable assembly method.
  • Torque test, barrel retaining screws
    The screw head should be redesigned to accept an Allen wrench . allow a higher preload torque to be applied without damaging the screwhead, .
  • Complications at screw removal in slipped capital femoral epiphysis treated by cannulated titanium screws
    We soon had to realise that the Allen wore off rapidly in several cases, making a more … A special wrench was developed allowing to apply a higher torque (Fig. 1).
  • Bicycles/Maintenance and Repair/Chain Rings - Wikibooks, open books for an open world
    The screws and nuts of chain ring fastenings are made with recessed allen key heads (hex wrench ), and at times the nuts might be slotted instead. Steel screws are likely to maintain higher torques than alloy, and the makers recommended torque settings will reflect this.
  • Grasp quality measures: review and performance
    3.3.2 Volume of the Grasp Wrench space (volume of P … the depen- dence of QL RW on the reference system used to compute torques , for instance using … However, this has not been widely considered due to its high computational cost. … with this problem, another alternative quality mea- sure is the volume of P (Miller and Allen 1999), .
  • Protocol Volume 15 Issue 4 Fall 2010
    For connection of larger wires, cables, or bus bars where hex head bolts or allen screws are used, a torque wrench is needed. torque screwdrivers can be split into two basic types: production drivers and manual screwdrivers. the production units are typically … … manual, as well, but since most connections requiring a torque wrench are not high volume tasks, a …
  • Offshore Drilling and Production Time-Saving Quick Connect and Disconnect Wellhead Connectors
    Atypical sequence would be to run in the actuation screws using an allen key, torque the screws to approximately 800 ft-lb using an impact wrench , and then complete makeup to 1,500 ft-lb using a torque wrench with a 3 … The higher torque figure specified for the flange virtually dictates the use of specialized hydraulic tooling if …
