Wiha 29245 Torque Screwdriver 636.8-637 In/oz 5/32 Drive

Product Description

The WIHA 29245 is a pre-set torque screwdriver designed for precision fastening applications where consistent, repeatable torque output is critical. Calibrated to a fixed range of 636.8 to 637 inch-ounces (4.5 Nm), this tool eliminates guesswork and helps prevent over-torquing sensitive fasteners. It features a 5/32-inch drive and a cushion grip handle for controlled, comfortable use during repetitive work. The overall length of approximately 5.1 inches makes it suitable for close-quarters tasks. Licensed electricians, instrumentation technicians, and electronics assembly professionals rely on pre-set torque screwdrivers like this one to meet torque-specification requirements on terminals, connectors, and panel components.

This torque screwdriver is well suited for electrical, electronics, and light mechanical assembly work where fastener torque must meet specific standards. Pre-set torque tools are commonly used in panel wiring, terminal block installations, and equipment assembly where manufacturer torque specs must be consistently met. The fixed calibration makes it particularly appropriate for quality-controlled environments and field service work requiring documented torque compliance. It is not tether capable, so it is best suited for bench or ground-level work where drop hazards are not a concern.

Key Features

• Pre-set torque range of 636.8 to 637 inch-ounces (4.5 Nm) for consistent, repeatable output
• Plus or minus 10% accuracy rating meets ASME B107.14M, BS EN 26789, and EN ISO 6789 standards
• 5/32-inch drive fits standard screwdriver bits for versatile tip compatibility
• Cushion grip handle reduces hand fatigue during repetitive fastening tasks
• Rated for a minimum of 5,000 cycles, supporting long service life in production and field use
• Not tether capable — suited for bench work and controlled environments

Compatibility

Designed as an OEM-style pre-set torque screwdriver for use with standard 5/32-inch drive screwdriver bits in electrical, electronics, and light mechanical assembly applications.

Installation Notes

Pre-set torque screwdrivers should be used by qualified technicians familiar with torque-specification requirements for the fasteners being driven. Always power down and de-energize electrical panels or equipment before performing fastener work on live components. Store the tool at its minimum torque setting when not in use to preserve the internal spring calibration. Periodic recalibration should be performed per the applicable service interval or as required by your quality program.
