Tap (threading tool) FANAR NARZYNKA UNF No10-32 DIN-22568 (2A) HSS 800

FANAR NARZYNKA UNF No10-32 DIN-22568 (2A) HSS 800 is a tap designed for cutting UNF No10-32 threads by hand or with a machine. It is produced to DIN‑22568 dimensional specifications and calibrated to a 2A tolerance class, providing consistent thread form suitable for assembly in maintenance and production environments. Manufactured from HSS 800, the tool offers elevated hardness and resistance to wear and moderate corrosion, making it suitable for repeated use in steel and similarly hard materials.

Advantages

The tap is compliant with DIN‑22568 standards and provides threads to the 2A tolerance grade, ensuring interchangeability and predictable fit with corresponding fasteners. Construction in HSS 800 balances toughness and cutting performance, improving service life compared with lower‑grade high‑speed steels. The design allows operation by hand or machine, and is suitable for both through and blind hole threading when proper technique is applied.

Suitable for

• Creating UNF No10-32 internal threads in steel and similar materials
• Maintenance and repair tasks requiring replacement or reinstatement of threaded holes
• Production environments where DIN‑22568 conformity and 2A tolerance are required
• Hand tapping and machine tapping operations, including through and blind holes

Key specifications

• Thread form and size: UNF No10-32
• Standard: DIN‑22568
• Tolerance class: 2A (external/interchangeable fit expectation)
• Material: High Speed Steel (HSS 800)
• Application: suitable for through and blind hole threading in steel and similar materials

How to use

Select an appropriate drill size for the UNF No10-32 tap and prepare the hole, ensuring correct alignment before starting the threading operation. For hand use, secure the workpiece and use steady pressure while turning the tap, backing off periodically to break chips. For machine use, set correct spindle speed and feed consistent with HSS tooling and the workpiece material; use suitable cutting fluid to reduce friction and prolong tool life. Clear chips frequently and inspect threads for conformity to expected fit.

Usage recommendations

Use appropriate cutting fluid when threading steel to improve finishing and reduce wear. When tapping blind holes, ensure sufficient chip evacuation by retracting the tap regularly. Inspect taps for wear or damage before use and replace if cutting quality deteriorates to maintain dimensional accuracy and surface quality of threads.
