Frequently Asked Questions

Should M36 Square Channel-Steel Washer — GB/T 852 (Series 083) 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.

What is the coarse-thread pitch of M36 for Square Channel-Steel Washer — GB/T 852 (Series 083)?

For M36 the standard coarse pitch is 4 mm — this is the value used for Square Channel-Steel Washer — GB/T 852 (Series 083).
