Frequently Asked Questions

What is the coarse-thread pitch of M36 for General Flat Washer — GB/T 97.1 / ISO 7089 (Series 087)?

For M36 the standard coarse pitch is 4 mm — this is the value used for General Flat Washer — GB/T 97.1 / ISO 7089 (Series 087).

What clearance and tapping drill suit M36?

Use a 39 mm clearance hole (ISO 273 medium) for through-fixing, or a 32 mm tapping drill for a coarse M36 thread.

Should M36 General Flat Washer — GB/T 97.1 / ISO 7089 (Series 087) be tightened by torque or by angle?

For critical structural joints at M36, angle-controlled or stretch-controlled tightening is more repeatable than pure torque — the friction scatter at large diameters can dominate the torque signal.

What grip range is typical for M36 structural bolts?

Grip ranges are highly application-dependent at M36. As a guide, choose a length that gives at least 1× the thread diameter engagement in the nut plus 2–3 thread pitches projecting.
