M28x1 fine thread hand taps
Hand Tap M28x1 ISO 529/2 6H HSS is designed for making M28 metric fine threads with a pitch of one millimeter in structural steels and metals up to eight hundred mega pascals. The two-member system - an inserting part (I) and a finishing part (II) - evenly distributes the torsional torque, improves the smoothness of machining and facilitates the maintenance of a class six H fit.
Technical data: nominal diameter twenty-eight millimeters; pitch one millimeter; profile sixty degrees in accordance with ISO 68-1; bore tolerance 6H in accordance with ISO 965; thread direction right; straight chip grooves to guarantee controlled evacuation. Made from HSS high-speed steel, in a precision grind, it stabilizes the edge and reduces micro-chipping. The ISO 529/2 standard defines the layout of work, and the order of operations in workshop practice is facilitated by Set Taps Manual M28x1. Recommended drill under thread: twenty-six and nine-tenths of a millimeter; the use of emulsion or active oil improves surface quality and extends the life of the blades.
- Guide stability - separation into two work stages reduces the risk of chafing and improves profile uniformity.
- Work resistance - HSS high speed steel in precision grind maintains edge sharpness and reduces wear.
- 6H fit accuracy - dimensional conformity is confirmed bypass/fail tests.
- Work organization - control of transitions and repeatability of results is supported by the M28x1 Hand Thread Set.
Compliance with ISO 529/2, ISO 68-1 and ISO 965 standards guarantees compliance with inspection instruments. As a result, the resulting threads maintain a stable outline and predictable geometry in both unit and short-run production.
