M45x3 fine thread hand taps
Hand Tap M45X3 ISO 529/2 6H HSS is designed for making M45 metric internal threads with a pitch of three millimeters in structural steels up to eight hundred mega pascals. Already at the planning stage of the operation, the order of the transitions and the unambiguous identification of the steps are ensured by a two-member sequence in accordance with ISO 529/2.
Working specifications: nominal diameter forty-five millimeters; stroke three millimeters; outline sixty degrees according to ISO 68-1; bore tolerance field class 6H according to ISO 965; right-hand design; straight chip grooves ensure uniform evacuation. Ground high-speed steel stabilizes the edge and reduces micro chipping. The ISO 529/2 workflow - introductory (I) and finishing (II) members - equalizes torsional loads and promotes alignment, and Set Taps Manual M45x3 with clear member markings organizes selection right from the bench preparation stage. Recommended drill under thread: forty-two millimeters; emulsion or active oil cooling improves surface finish.
- Smooth outline formation - stage I prepares the geometry, and stage II closes the profile, reducing torque pulsation and chafing.
- High edge life - HSS grinding maintains low micro roughness and slows abrasion during handwork.
- Grade 6H accuracy - controlled effective diameter promotes a positive pass/fail test result.
- Repeatability of operations - on the bench, the M45x3 Hand Thread Set organizes the sequence of operations and standardizes control.
Meeting the requirements of ISO 529/2 (design), ISO 68-1 (outline geometry) and ISO 965 (tolerances class 6H) guarantees compatibility with inspection instruments; the M45x3 design translates into a stable thread profile and consistent dimensions in unit and short-run machining.
