Common questions
What size drill do I use to tap M36 × 1?
Use a 35 mm drill. This is the standard tap drill for M36 × 1; for hard materials or deep threads a slightly larger drill reduces tapping torque.
What is the pitch of M36 × 1?
The pitch of M36 × 1 is 1 mm (fine), meaning the thread advances that distance in one full turn.
Where can I find other ISO Metric Fine Thread, pitch 1 and 1.25 sizes?
The full ISO Metric Fine Thread, pitch 1 and 1.25 table, with every size and a live filter, is on its standard page, and the Thread Finder searches all 73 standards at once.
