TECWERK tool extension DIN 377 – zinc-plated, 9 mm square shank

A TECWERK tool extension DIN 377 designed to extend reach for hand taps and hand reamers, providing standardised square engagement for reliable manual threading operations.

• DIN 377 standard for reliable compatibility
• Zinc-plated finish for corrosion resistance
• Square shank 9 mm to DIN 10 / ISO
• Total length 130 mm for extended reach

Improved accessibility for confined threads

The 130 mm overall length provides a clear practical advantage when access is restricted by fixtures or recessed components. By extending the effective working distance, the extension bar reduces the need for customised tooling or awkward handling, which in turn lowers setup time and the risk of thread damage. The combination of extended reach with a compact profile supports efficient, repeatable manual tapping and reaming in production and repair environments.

Secure drive transfer with standardized shank geometry

Compatibility with DIN 377 and a 9 mm square shank manufactured to DIN 10 and ISO tolerances ensures a firm mechanical connection to conventional tap wrenches and handles. This standardised geometry improves torque transmission during hand-threading and reduces the likelihood of slippage or rounding, resulting in fewer interrupted cycles and less rework. The standardized fit supports rapid tool changes and smooth integration into existing workshop routines.

Corrosion protection that preserves service life

The zinc-plated finish provides a protective layer against surface corrosion in typical workshop atmospheres, extending service intervals and preserving dimensional accuracy of the shank. Zinc plating is a cost-efficient surface treatment that minimises seizure and eases handling after repeated use, contributing to predictable maintenance planning and reduced total cost of ownership for manual tooling accessories.

Practical specification and workshop integration

Supplied as a single unit and specified for use with hand taps and hand reamers, the extension features a M13–16 thread interface and a material composition of zinc, offering a balance of form stability and economical production. The simple design facilitates quick inspection and replacement, while adherence to established standards ensures compatibility across a wide range of tapping tools and handles commonly found in maintenance, toolroom and light production settings.
