Please note : Images are of a generic standard Scrooz bolt and nut and thread lengths vary slightly per size so please check with us before ordering if this dimension is critical. Typically, thread lengths for our hex bolts will be to the recognised international metric standard as follows :
- For bolt lengths up to 125mm - 2 x diameter + 6mm
- For bolt lengths 125mm to 200mm - 2 x diameter + 12mm
- For bolt lengths over 200mm - 2 x diameter + 25mm
So for example an M12 x 130mm bolt will have a thread length of
24 + 12 = 36mm
All bolt lengths are measured from under the head.
