TECWERK machine thread tap M16×2 mm (DIN 376C) — HSS‑Co, nitrided and vapourised with 40° right‑hand spiral

TECWERK machine thread tap M16×2 mm (DIN 376C) is a spiral‑fluted, cobalt high‑speed steel tap designed to produce metric ISO threads in blind holes, optimised for stainless, acid‑ and heat‑resistant steels with elevated tensile strength.

• HSS‑Co construction for high wear resistance
• Nitrided and vapourised surface treatment
• Right‑hand 40° spiral for blind holes
• ISO2 (6H) tolerance for precise metric threads

Reliable performance for blind‑hole threading

The HSS‑Co composition combines hardness and toughness to withstand the demands of machining high‑strength stainless and heat‑resistant alloys. The right‑hand 40° spiral actively directs chips back into the flutes, reducing the risk of chip packing in blind holes and lowering the chance of tap breakage. The combination of a ground flank relief and the vapourised layer improves edge stability and extends component life, resulting in fewer tool changes and less unplanned downtime.

Threads that fit first time

Designed to the DIN 13 Part 1 metric standard and manufactured to ISO2 (6H) tolerance, this tap produces threads with consistent pitch and flank geometry suitable for assembly without rework. ISO2 (6H) indicates a standard internal tolerance for general industrial use, meaning mating bolts and nuts will achieve reliable engagement and predictable preload. This level of precision supports efficient throughput and reduces scrap from mismatched fittings.

Suited to demanding materials and applications

Specified for machining stainless, acid‑ and heat‑resistant steels with tensile strength above 850 N/mm², this tool is tailored to applications where corrosion resistance and elevated strength are required. The designation type VA signals suitability for stainless materials, while Form C indicates the tap geometry optimised for such alloys. Where conventional taps struggle with long, stringy chips or rapid edge wear, this design maintains thread quality and dimensional control.

Workshop integration and handling benefits

A shank 12 mm diameter provides secure clamping in standard toolholders and machines, while the visible blue ring serves quick identification on the bench. The vapourised surface and nitriding process reduce friction and improve release from sticky materials, supporting faster cycle times and improved tool life. For procurement and stock management, the robust specification and clear identification simplify selection and reduce the risk of ordering incorrect thread forms.

FAQ

What materials is this tap designed for?
The TECWERK M16×2 mm machine thread tap is specified for stainless, acid‑ and heat‑resistant steels with tensile strength above 850 N/mm² and is manufactured to perform reliably in such alloys.

Is this tap suitable for through‑holes as well as blind holes?
While optimised for blind holes thanks to the right‑hand 40° spiral, the tool can also be used in through‑hole applications where the thread form and material compatibility are appropriate.

What does ISO2 (6H) mean for thread fit?
ISO2 (6H) denotes a standard internal tolerance providing a general‑purpose fit; the tap produces metric threads conforming to DIN 13 Part 1, ensuring consistent engagement with standard external threads.
