Spanner & Drive for M36 Flat Washers

Drive geometry for M36 Flat Washers is given by the row above; match the tool to the listed values.

Common Applications for M36 Flat Washers

M36 Flat Washers are commonly specified for high-load load-spreading on structural joints.

Installation Tips for M36 Flat Washers

  • At M36 the stretch in the bolt becomes the controlling factor — for critical joints, use angle-controlled or stretch-controlled tightening instead of pure torque.

Mating Parts for M36

A M36 flat washer pairs with a M36 bolt/screw and matching M36 nut.

Frequently Asked Questions

What is the coarse-thread pitch of M36 for Flat Washers?

For M36 the standard coarse pitch is 4 mm — this is the value used for Flat Washers.

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 Flat Washers 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.
