Torque Angle Gauge Automotive manufacturers prescribe both torque and rotational angle settings for fastening elements used in vehicles. Angle controlled torquing gives initially “snug” torque, then turns the fastener a step further to the optimum torquing angle. Torque is measured to the maximum safe working load, while preventing overtorquing and damage to the fasteners. 7851-DW 8951-DW 1/2" 1/2" EAN-Code 731415+ 1846602 1846619 female square drive on the input side. male square drive on the output side. Easy to use, precision work: Window clicker torque wrench Drive g 1 1 1/2" 3/4" 3/4" 3/4" 155 520 female square drive on the input side. male square drive on the output side. 000000ENG Art.-Code Large, easy to read scale with oil resistant, non-reflective surface. The angle indicator clearly indicates the angular reading. The adjustable reference arm is firmly attached to a non-moving part of the machine and prevents the scale turning. www.bahco.com Torque wrench with permanent ratchet Torque wrench for interchangeable insert tools Magnifying window scale enables easy, accurate read-off. For all assembly jobs, especially where access with conventional sockets is not possible. Strong, reversible ratchet, 32 teeth, 11.25° pivot range. A spring-loaded ball ensures the sockets are firmly attached and cannot fall off. The release mechanism enables sockets to be removed and changed quickly at the push of a button. Right-hand turn for controlled screw tightening (the torque wrench can also be used for controlled left screw tightening, when turned over by 180°). The required torque is quickly set via a pull-out setting knob in the handle. Accuracy is in accordance with DIN/ISO 6789.1993, EN26789.1994. (7 Nm) (2 Nm) When the preset torque is attained, the wrench produces both audible and tactile signals. The right torque readings at a glance Right-hand turn for controlled screw tightening. Accuracy is in accordance with DIN/ISO 6789.1993, EN26789.1994 Measuring Range in Nm = Newton-Metre Art.

For various reasons, it may be necessary in practice to add an extension arm. To this end it is necessary to adjust the programming. The required settings may be calculated using the following formula: C= L1 x T L1 + B L1= Length of the lever arm on the torque wrench itself 7451-DEMO-KIT B = Distance between the two pivot centres after attaching the extension T = Tightening torque of the bolt C = Setting value Example: L1 = 425 mm B = 40 mm C= T = 20 Nm C=? 0,425 x 20 0,425 + 0,040 C = 18,28 Nm B L1 = 8,5 0,465 = 18,28 Torque wrench with permanent ratchet Torque wrench for interchangeable insert tools Magnifying window scale enables easy, accurate read-off.
