With adjustable torque settings and exceptional accuracy, AccuTec cordless fastening tools meet the rigorous demands of modern assembly. These lightweight, compact tools feature infinitely variable speed adjustment. Models are available to cover torque ranging from 0.5 to 60 newton-meters. The tools can accept 12-, 14.4- and 18-volt lithium batteries.

The tools provide visual and audible signals that a fastener has been installed correctly or incorrectly. The battery management system prevents installation of fasteners if battery power is insufficient. The tools are ISO5393 compliant with ±10 percent accuracy guaranteed and ±5 percent accuracy demonstrable with a CMK or more than 1.67. 

Fein’s PowerDrive brushless motor is rated for more than 1 million cycles. Engineers can program speed, angle, time, soft start, re-hit detection, re-hit prevention, cross thread reduction, constant throttle, and threshold strategy.

With AccuTec ASM 18 pistol-grip tools, motor speed is electronically controlled, so it remains constant under load until the moment the tool clutches out. AccuTec ASW 18 right-angle nutrunners have a variety of interchangeable heads for various applications.

AccuTec parameter control (APC) software is free to download with no subscriptions. For re-hit detection, the APC can be set to detect a high load and clutch-out on startup. When triggered, the tool is locked for a user-defined period of time to inform the operator that a re-hit has taken place or a cross-thread has occurred. For re-hit prevention, the APC can be configured with a user-defined trigger delay telling operators to avoid rapid re-hits to an already tightened fastener. For cross-thread detection, the APC can be used to configure the tool to begin in reverse prior to tightening the fastener to ensure correct thread alignment. For soft start, the APC allows for user-defined ramp up times up to 1 full second. This is useful when combined with cross-thread prevention, giving the operator time to align the fastener.

Threshold technology lets engineers deploy clutch tools where a DC tool would otherwise be required. AccuTec automatically downshifts when a user-defined percentage of the target torque is reached. The technology uses the load on the motor and the draw on the battery to approximate a threshold similar to programming a DC tool.
