Common Applications for M36 Tab Lock Washer for Round Nut — GB/T 858 (Series 073)

M36 Tab Lock Washer for Round Nut — GB/T 858 (Series 073) are commonly specified for high-load load-spreading on structural joints.

Installation Tips for M36 Tab Lock Washer for Round Nut — GB/T 858 (Series 073)

  • 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.

Frequently Asked Questions

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 Tab Lock Washer for Round Nut — GB/T 858 (Series 073) 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.

Which washer dimensions matter most for M36?

For a flat washer, the outside diameter (the bearing surface) and the thickness control how the load is spread under the head and how much elastic preload is preserved. The inside diameter must clear the bolt body but not be so large that the head bears mostly on the washer's outer rim.
