Click-type torque screwdriver handles 0.5 to 11.5 in-lb with 1/4 in drive and ESD-safe grip
This click-type torque screwdriver delivers an adjustable range from 2.5 to 11.5 inch-pounds for precise fastener control. The 1/4-inch drive accepts replaceable bits to suit various applications. A calibration certificate is included with the new tool. Carbon steel construction provides durability for professional use.
The ESD-safe handle protects sensitive electronic components during assembly work. Clockwise operation suits standard tightening tasks for technicians and engineers. This model is not insulated, so it must not be used on live electrical circuits. It also lacks non-sparking certification for hazardous environments.
The torque window of 2.5 to 11.5 inch-pounds determines whether this driver matches the fastener specification. Builders needing higher torque values must select a different tool. The fixed 1/4-inch drive size also dictates bit compatibility for the job.

The 0.5 in-lb figure is the scale resolution; the working range is 2.5 to 11.5 in-lb, so select torque values inside that window.
The click mechanism releases between 2.5 and 11.5 in-lb, letting you set any value in that span for repeatable clockwise tightening.
The 1/4 in hex drive accepts standard 1/4 in insert bits; the replaceable-bit design lets you swap tips while staying within the 2.5 to 11.5 in-lb range.
