3/8" Square Drive Professional Adjustable

Incorporates 'click' sound and 'snap' feel to indicate when torque setting has been reached. Sliding switch on the ratchet head for instant direction reversal (except model 300 and 330, which has a push through square drive). Setting lock to prevent accidental adjustment of the torque setting. Scale located within handle Nm/lbf.ft graduated (kgf.m or ibf.in scale also available, supplied to order). Accuracy to 3%. Supplied in sturdy blow moulded box for protection. Supplied with a traceable calibration certificate to satisfy the requirements of ISO 9000 quality systems. With ratchet.

Torque Range: 8-60Nm 5-45ibf.ft

Standard Series Torque Multiplier

The 'Standard series' torque multiplier has been designed for the specialist user where it is necessary to provide higher torque than would otherwise be possible due to limitations on space or operator strength. This series employs multiple stage epicyclic gearing to give a wide range of torque outputs and ratios to suit most applications. The torque multiplication is accurate to more than plus/minus 4% with a maximum output of 47,500Nm. *Models contain the AWUR 'anti wind up ratchet' mechanism. As with any high ratio gearbox (25:1 or more) a certain amount of wind-up (spring) has to be taken up before any useful tightening work can be applied to the nut. Each time the input device is released, the wind-up will rotate back against the direction of operation.The AWUR mechanism retains all of the wind up forces as they are created locking the multiplier onto the nut being tightened. This means that even when used upside down the multiplier will support it's own weight.



Torque Range: 3400Nm 2500 Ibf.ft
Square Drive: 3/4 '' Input 1'' Output

1/2 & 3/8'' Square Drive Professional Torque Wrench - Industrial Ratchet Models

All Norbar torque wrenches are designed and manufactured to exceed the following national and international standards: BS6703: 1988, ISO 6789: 1992 & U.S.A.GGG-W-00686-C (GSA-FSS).



The professional torque wrench offers an ideal combination of accuracy, robust construction, comfort and ease of use. The push-through ratchets on these models are robustly engineered for strength and durability. The strength and high wear resistance comes from the design of the tooth pattern while the principle of offset ratchet pawls gives a narrow engagement angle. Accuracy of +/-3% of reading exceeds all international standards for torque wrenches. Every wrench is supplied with a calibration certificate to satisfy the requirements of ISO 9000-2000. Soft feel handle provides excellent grip even in oily conditions. Handle material and lens resist all chemicals in common automotive, industrial and aviation uses. Locking mechanism prevents accidental adjustment of the wrench during operation. Long scale graduated in Nm and lb/ft allows for foolproof and accurate setting, kgf/m and lbf/in scales are also available. Supplied in moulded box for storage and protection.

Torque Range: 8-60Nm 5-45ibf.ft
