Hand tap DIN 352 No. 3 M20 x 2.5 mm HSS ISO2 (6H) — metric hand tap by TECWERK

A Hand tap DIN 352 No. 3 M20 x 2.5 mm HSS ISO2 (6H) TECWERK designed for cutting metric internal threads in steels with a tensile strength of up to approximately 900 N/mm²

• HSS cutting material for durable performance
• Metric thread M20 x 2.5 mm to ISO standard
• Tolerance ISO2 (6H) for consistent fits

Consistent thread quality for reliable assemblies

The tool is manufactured to DIN 352 and intended specifically for the production of metric internal threads, which ensures repeatable results in serial and single-part work. Made from HSS, the tap maintains cutting geometry under load and is suitable for steels up to 900 N/mm², so the primary benefit is predictable, high-quality threads that reduce the need for rework. The standardised geometry also means compatibility with commonly used fasteners and gauges, supporting efficient assembly processes and predictable part interchangeability.

Precision tolerance for assembly accuracy

With a tolerance ISO2 (6H), the thread form targets a balance between manufacturing ease and functional clearance. The defined tolerance field minimises variations between mating parts, which directly reduces assembly problems and rejects. The shaft Ø 16 mm provides a secure fit in standard holders and hand tap wrenches, keeping alignment stable during cutting; as a result, thread runout is reduced and component fit is improved. For applications where dimensional conformity and dependable torque transmission matter, this tolerance class is an effective choice.

Robust design and practical handling to lower downtime

The combination of HSS cutting material and a right-hand cutting geometry yields a tool that is robust in workshop conditions and resists premature wear during typical tapping operations. The tool's design supports manual use as a hand tap while remaining suitable for controlled machine tapping where appropriate. Reduced tool failure and consistent performance mean fewer interruptions to workflow and a lower incidence of damaged workpieces, which together contribute to improved productivity and lower operational costs over time.

FAQ

What materials is this hand tap suitable for?
The TECWERK hand tap is specified for use in steels up to approximately 900 N/mm²; the HSS cutting material provides the necessary wear resistance for these applications.

Which thread does the tool produce?
This tool produces a metric internal thread of M20 x 2.5 mm, conforming to DIN 13 Part 1 thread form and manufactured to DIN 352 dimensions.

What does the ISO2 (6H) tolerance mean for assemblies?
The ISO2 (6H) tolerance provides a medium fit range that balances manufacturing ease with reliable mechanical engagement, reducing the risk of assembly mismatch when paired with standard ISO bolts.

Will the shaft diameter fit standard tap holders?
The shaft Ø 16 mm is intended to fit standard hand tap wrenches and holders designed for 16 mm shanks, offering secure clamping and stable alignment during tapping.
