M3x0.35 INOX machine tap – universal HSSE tool to ISO 529
The Fra M3x0.35 INOX machine tap compliant with ISO 529 is designed for precision tapping of holes with a diameter of 3 mm and a fine pitch of 0.35 mm in stainless and structural steels. HSSE high-speed steel with 5% cobalt ensures a hardness of 66 HRC and long cutting edge life, even when machining difficult-to-machine materials. Form C with straight flutes provides universal use in through and blind holes. The 6H tolerance in accordance with ISO 529 confirms international dimensional standardization.
Key features of the M3x0.35 tap for through and blind holes
- Compliance with ISO 529 ensures international dimensional standardization and full compatibility with clamping systems used worldwide
- Manufacturing precision to 6H tolerance ensures dimensional repeatability and full thread interchangeability in series production of precision components
- Durability increased by the addition of 5% cobalt allows operation at temperatures up to 650°C without loss of cutting edge performance
- Material versatility covering 304 and 316 austenitic stainless steels, structural steels up to 800 MPa, and nonferrous metals
- Compatibility with ER11 holders and tapping heads for CNC machining centers with synchronous tapping and automatic tool changing
- M3x0.35 general-purpose machine tap with form C allows through and blind holes to be tapped with a single tool without the risk of jamming
The Fra M3x0.35 HSSE machine tap is used in electronics and precision engineering requiring international standardization. It is suitable for export production. The tap drill diameter for the M3x0.35 thread is 2.65 mm.

Frequently asked questions
The M3x0.35 ISO 529 HSSE tap with form C chamfer and straight flutes is universal – suitable for both through and blind holes. Its design ensures proper chip evacuation in both hole types.
The M3x0.35 ISO 529 HSSE tap produces an internal thread in tolerance class 6H. The 6H designation specifies the permissible deviations of the thread pitch and minor diameters – the digit 6 indicates the width of the tolerance zone (medium), while the letter H indicates the zone's position at the zero line. The 6H tolerance ensures a proper fit with screws having a 6g tolerance.
ISO 529 is an international standard specifying tap dimensions and tolerances, ensuring compatibility across global markets. DIN standards are German equivalents, often identical or very similar to ISO standards.
