M40x3 fine thread hand taps
Hand Tap M40x3 ISO 529/2 6H HSS is designed for making M40 metric fine threads with a pitch of three millimeters in structural steels and metal alloys with strengths up to eight hundred megapascals. The two-member design - an insertion threader (I) and a finishing threader (II) - ensures even distribution of torsional torque, stable process and maintenance of a six H fit class.
Performance parameters: nominal diameter forty millimeters; pitch three millimeters; outline sixty degrees according to ISO 68-1; hole tolerance field 6H according to ISO 965; right-hand thread direction; straight chip grooves promoting controlled evacuation. HSS high-speed steel in a precision grind reduces micro-crushing and stabilizes edge sharpness. The ISO 529/2 standard defines the work layout, and the transparency of the steps and the repeatability of the results support Set Taps Hand M40x3. Recommended drill bit for the thread: thirty-seven millimeters; the use of emulsion or active oil increases blade life and improves thread surface quality.
- Guide stability - the separation of the process into two stages reduces torque fluctuations and improves the uniformity of the outline.
- Work organization - in assembly practice, the order of operations is facilitated by the M40x3 Hand Thread Set.
- Edge resilience - HSS high-speed steel maintains sharpness after grinding and slows wear in shop work.
- 6H fit accuracy - dimensional control confirmed by "pass/fail" gauges.
Meeting the requirements of ISO 529/2, ISO 68-1 and ISO 965 guarantees full compliance with inspection instruments, and the threads produced maintain a predictable profile and repeatable geometry in both unit and short-run production.
