Wiha 0.8 - 5.0 Nm SoftFinish TorqueVario-S Handle (28553) is a precision torque handle designed for fastening applications that require adjustable and repeatable torque control across industrial, automotive, and electronic assembly work. Operating within a range of 0.8 to 5.0 Nm, this tool helps technicians tighten fasteners to exact specifications while reducing the risk of overtightening, stripped threads, broken fasteners, or damage to sensitive components. The handle uses a mechanical click mechanism that provides both audible and tactile feedback when the target torque is reached, then automatically resets for the next fastening cycle. Built with a SoftFinish cushion grip and an Easy View torque scale, it combines accuracy, comfort, and professional usability in one compact torque solution. Key Features and Benefits: Adjustable torque range: Provides variable torque settings from 0.8 to 5.0 Nm for multiple fastening requirements. Certified accuracy: Maintains a +/-6% tolerance and aligns with ASME B107.14m, EN ISO 6789, and BS EN 26789 standards. Audible and tactile click signal: Mechanical release indicates when the preset torque value has been reached to help prevent over-tightening. Traceable calibration: Each handle is laser-calibrated and includes a serialized calibration certificate for professional quality control. SoftFinish ergonomic grip: Multi-component cushion handle improves comfort and supports efficient manual force application. Automatic reset function: Internal mechanism resets immediately after each completed torque cycle for faster repetitive use. Easy View scale: Integrated window allows quick confirmation and adjustment of the selected torque setting. Accessory compatibility: Designed to work with Wiha Torque Control Blades as well as bit and socket adapters. Specifications: SKU: 28553 UPC: 084705285535 Product Type: Adjustable Torque Handle Torque Range: 0.8 - 5.0 Nm Accuracy: +/-6% Weight: 0.6 lb Width: 1.40 in Height: 1.40 in Length: 8.00 in Country of Origin: Germany Standards Compliance: ASME B107.14m, EN ISO 6789, BS EN 26789 Handle Type: SoftFinish Cushion Grip Scale Type: Easy View integrated window scale Included Items: 1 SoftFinish TorqueVario-S Handle, 1 Torque Adjustment Tool, 1 Calibration Certificate How to Use: Select the torque value: Insert the included torque adjustment tool into the handle's adjustment port. Set the scale: Rotate the adjustment tool until the required Nm value aligns correctly in the Easy View scale window. Install the attachment: Insert a compatible Wiha Torque Control Blade, bit adapter, or socket adapter into the front of the handle until it is fully seated. Position the tool on the fastener: Engage the blade or attachment securely with the fastener before applying force. Apply torque smoothly: Turn the handle in a controlled clockwise motion while maintaining proper alignment. Stop at the click: Cease force immediately once you hear the click and feel the release mechanism activate. Repeat the process: Continue to the next fastener as needed since the tool resets automatically after each cycle. Store with documentation: Keep the handle, adjustment tool, and calibration certificate together in a protected storage area.
