Frequently Asked Questions

What is the coarse-thread pitch of M14 for Spring Lock Washers?

For M14 the standard coarse pitch is 2 mm — this is the value used for Spring Lock Washers.

What clearance and tapping drill suit M14?

Use a 15.5 mm clearance hole (ISO 273 medium) for through-fixing, or a 12 mm tapping drill for a coarse M14 thread.

Which washer dimensions matter most for M14?

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.
