What is M10 nut?
If the size is M10 x 25, that would mean that the diameter is 10 mm. Since there is no thread pitch listed, the fastener is assumed to have a coarse thread. The 25 indicated a length of 25 mm. A matching nut would be labeled M10, which also doesn’t require a thread pitch since it’s a course thread fastener.

When a jam nut is used where is it placed and what torque should be applied?
Order is important. You always want to put the thin (or jam) nut on first against the joist. Tighten it to between 25 and 50 percent of the total tightening torque and only that amount, otherwise you will negate the locking.
