Tool extension DIN 377 — zinc, square shank 14.5 mm (M22–M24) by TECWERK

The Tool Extension DIN 377 is a 175 mm workshop extension for manual threading and reaming tasks, designed to fit hand taps and hand reamers with a DIN 10 / ISO square interface

• DIN 377 standard for secure compatibility
• 175 mm overall length for extended reach
• Zinc body with M22–M24 thread connection
• Square shank to DIN 10 / ISO for hand tools

Assured fit with industry standards for stable manual work

The extension is manufactured to DIN 377, providing a defined interface between tap wrench and tool extension. The 14.5 mm square shank conforms to DIN 10 / ISO, which ensures a stable seating and reduces play during manual tapping and reaming. The integrated M22–M24 thread connection maintains a secure mechanical link to compatible tap holders, translating into consistent alignment and fewer cross-threading incidents when working by hand.

Longer reach for hard-to-access threads and neat workflows

With a 175 mm overall length the extension gives measurable extended reach for deeper or recessed holes, enabling access without improvised extensions that compromise accuracy. The zinc construction offers corrosion resistance suitable for workshop environments and keeps the tool lightweight for comfortable manual handling. Reduced bulk at the hand wrench improves balance, so operators can maintain control and finish threads more consistently.

Purpose-built for manual taps and reamers with predictable torque transfer

Designed specifically for use with hand taps and hand reamers, the extension preserves the intended geometry of manual tapping setups and supports controlled torque transfer. The square shank to DIN 10 / ISO mates with common tap wrenches, so the assembly behaves predictably during the cutting and finishing operations. For users with limited technical background, this means safer manual threading and a lower likelihood of damaged threads or tools.
