Common Applications for M24 Spring Lock Washer — GB/T 5782 / ISO 4014 (Series 003)

M24 Spring Lock Washer — GB/T 5782 / ISO 4014 (Series 003) are commonly specified for high-load load-spreading on structural joints.

Installation Tips for M24 Spring Lock Washer — GB/T 5782 / ISO 4014 (Series 003)

  • At M24 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

Should M24 Spring Lock Washer — GB/T 5782 / ISO 4014 (Series 003) be tightened by torque or by angle?

For critical structural joints at M24, 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 M24 structural bolts?

Grip ranges are highly application-dependent at M24. 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 M24?

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 M24 for Spring Lock Washer — GB/T 5782 / ISO 4014 (Series 003)?

For M24 the standard coarse pitch is 3 mm — this is the value used for Spring Lock Washer — GB/T 5782 / ISO 4014 (Series 003).
