SKU CH-GRAG-942VN

A 1/4-inch click-type torque screwdriver adjustable from 25 to 55 inch-pounds with 2.5 inch-pound increments and a calibration certificate included

  • Precise torque control with 25 to 55 in-lb range
  • Fine 2.5 in-lb adjustment steps for accurate fastening
  • Click-type mechanism gives clear audible and tactile feedback
  • 1/4 in drive accepts interchangeable bits for versatility
  • Calibration certificate included ensures traceable accuracy

Precision torque control

This Wera Tools torque screwdriver delivers a 25 to 55 inch-pound range with a 2.5 inch-pound resolution. The click-type mechanism provides audible and tactile feedback when the set value is reached. A calibration certificate is included to verify accuracy out of the box. It accepts replaceable 1/4 inch drive bits for versatile fastener work.

Click-type mechanism limits

The click action signals the target torque but does not prevent further tightening if the user continues to apply force. The tool operates in a clockwise direction only, so it cannot be used for left-hand threads or reverse torque verification. There is no ratcheting function, requiring the operator to reposition the grip after each click. It lacks ESD-safe, insulated or non-sparking construction for specialised environments.

25 to 55 in-lb range

This torque window suits many mechanical assembly tasks but will not cover very low-torque electronics or high-torque automotive fasteners. Builders needing settings below 25 inch-pounds or above 55 inch-pounds must select a different tool. The fixed range cannot be adjusted or extended beyond the stated limits.

Questions about this item

Should I pick the 25 in-lb or the 55 in-lb setting for my application?

The screwdriver covers a continuous 25 to 55 in-lb range. Select any value inside that window; the 2.5 in-lb increment lets you dial the exact torque the fastener requires.

What does the 25 to 55 in-lb range actually deliver on the bench?

It provides repeatable click-type torque from 25 up to 55 in-lb in 2.5 in-lb steps, so each fastener receives the precise inch-pound force you set.

How does the 1/4 inch drive interface limit the bits I can use?

The 1/4 inch hex drive accepts any standard 1/4 inch insert bit; the replaceable-bit design means you swap tips without changing the torque body.
