Gedore TF-K300 Tool Set Gedore TF-K300 300 pcs

The Gedore TF-K300 torque wrench is an adjustable, robust tubular tool with integrated ratchet and square drive, designed for controlled screw tightening in the common range of 20–850 N·m (15–630 lbf·ft). Classified to DIN EN ISO 6789-2:2017 Type II Class A and delivered with a traceable test certificate, the wrench provides bi-directional tightening and a precise jump-off mechanism that gives a clear tactile and audible signal when the set torque is reached. Its durable powder-coated steel construction, galvanized ratchet, mushroom-style 1/2" square with ball lock (and square socket with pin retention from 3/4"), and ergonomic handle make it suitable for industrial and trade applications.

Advantages

The torque wrench is factory-adjusted to a maximum permissible deviation of ±3%, offering higher accuracy than the standard ±4%. A double scale for N·m and lbf·ft with a protected vernier allows fine settings (N·m vernier for intermediate values; lbf·ft via main scale). Vertical, centrally positioned scales with unit labelling in the scale frame and an enlarged viewing window reduce parallax and protect markings from abrasion and contamination. Additional features include a clearly recognisable hand-centering and calibration aid in the handle, roll-away protection to prevent the tool from rolling when set down, and a robust construction intended for frequent professional use.

Suitable for

• Controlled torque fastening in industrial assembly and maintenance
• Automotive repair and mechanical workshops
• Professional trades requiring accurate bolt tightening

How to use

Set the desired torque using the main scale and the vernier for intermediate N·m values, aligning the scale line directly above the scale to avoid parallax errors. Select the direction for tightening or loosening and engage the ratchet. Apply steady force until a clear tactile and audible trigger indicates the preset torque has been reached, then stop applying torque. Use the hand-centering aid on the handle to maintain correct grip and control during operation.

Usage recommendations

For reliable calibration and traceability, keep the included DIN EN ISO 6789-2:2017 test certificate with the tool and follow the manufacturer's calibration intervals. Store the wrench in its case to protect scales and mechanism from abrasion and contamination.
