Wera 05027936001 Preset Torque Screwdriver 5 Nm T20

Product Description

The WERA 05027936001 is a preset torque screwdriver designed for Torx socket screws, factory-set to a fixed 5 Nm torque value with no field adjustment required. It accepts a T20 Torx tip and delivers repeatable torque output within plus or minus 10% accuracy, making it suitable for fastening applications where consistent clamping force is critical. The overall length is 225 mm (approximately 8.86 inches), with a shaft length of 65 mm (approximately 2.56 inches). Because the torque setting is locked at the factory, there is no risk of accidental over- or under-torquing during routine use. Electricians, HVAC technicians, and mechanical contractors use preset torque screwdrivers like this one when working with terminal blocks, panel components, and equipment covers that carry specific torque requirements.

This screwdriver is suited for light-duty precision fastening tasks in residential and commercial service environments. It is particularly useful when manufacturers specify a fixed torque value for electrical enclosures, control panels, junction boxes, or equipment access hardware. The T20 Torx drive accommodates the socket screw sizes commonly found in these applications. Because the torque is preset and non-adjustable, it is intended for single-torque applications where the target value is 5 Nm.

Key Features

• Factory-preset at 5 Nm - no field adjustment needed, eliminates setting error
• T20 Torx tip for socket screws common in electrical and mechanical assemblies
• Plus or minus 10% torque accuracy for repeatable, consistent fastening
• Overall length of approximately 8.86 inches for standard hand access
• Single-piece tool - no interchangeable parts to lose on the job
• Not tether capable - for use in environments where dropped-tool programs are not required

Compatibility

Designed for use with T20 Torx socket screws requiring a preset torque of 5 Nm. Suitable for electrical, HVAC, and mechanical fastening applications specifying this torque and drive size.

Installation Notes

This tool is intended for use by licensed electricians, HVAC technicians, and qualified mechanical service personnel. Always verify the fastener manufacturer's torque specification before selecting a preset screwdriver. Because the torque setting is non-adjustable, confirm the 5 Nm value matches the application requirement before use. Store the screwdriver properly to prevent damage to the preset clutch mechanism, which can affect calibration accuracy over time.
