M16x2mm Machine Tap DIN 376C HSS Form C Right-Hand Spiral Flute ISO2 6H Thread, 12mm Shank - Ruko GmbH

Combining HSS construction, DIN 376C thread form and an ISO2 (6H) tolerance, this machine thread tap delivers consistent, production-grade M16×2 blind threads in unalloyed and low-alloy steels up to 800 N/mm² as well as in malleable cast iron and non‑ferrous metals; order directly via Metav Werkzeuge or consult the specialists for application advice.

Machine thread tap DIN 376C M16×2 HSS 6H – RUKO

A Machine thread tap DIN 376C M16×2 HSS 6H – RUKO for producing accurate blind ISO metric threads in unalloyed and low-alloy steels, malleable cast iron and non‑ferrous metals in industrial tapping operations

• HSS construction for robust wear resistance
• DIN 376C profile for consistent thread geometry
• ISO2 (6H) tolerance for reliable internal fit

Consistent, production-grade M16×2 threads for industrial use

The M16×2 machine tap is built in HSS, providing a durable cutting edge for repetitive production work. The DIN 376C thread form ensures compliant metric thread geometry according to DIN standards, while the ISO2 (6H) tolerance offers a medium internal fit that reduces rework and scrap. Designed for machine tapping into blind holes, the tool supports repeatable results on assembly components where thread quality directly affects product function. The clear specification and standard conformity make it suitable for series production and maintenance environments.

Geometry and chip control optimised for blind-hole tapping

A 35° right-hand helix and flank honing (flank honing) improve chip formation and evacuation in blind holes, reducing the risk of chip jamming and surface damage. The Form C cut, combined with honed flanks, produces cleaner thread flanks and fewer burrs, which simplifies subsequent assembly and inspection. This optimised geometry translates into fewer rejects and less secondary finishing, enhancing throughput in shops where downtime and part rejection are costly.

Material compatibility and application scope

The tool is specified for use in unalloyed and low-alloy steels up to 800 N/mm² tensile strength, in malleable cast iron and in non‑ferrous metals, enabling versatility across a wide range of workshop tasks. The HSS substrate balances toughness and wear resistance, suitable for conventional machine tapping operations where heat and varying material properties are present. As a result, the tap is appropriate for production runs, repair jobs and toolrooms that require a reliable, general‑purpose machine tap for medium‑strength materials.

Practical features for reliable machine setup and handling

A 12 mm shank diameter accommodates standard collets and holders for secure mounting in tapping heads and CNC spindles. The right‑hand cutting direction matches typical spindle rotation, simplifying integration into existing processes. Compliance with DIN 13 Blatt 1 metric thread standards provides clarity for quality control and inspection routines. Together, these practical details support consistent set‑up times and predictable machining behaviour, which contributes to smoother production planning and fewer interruptions.
