Please contact us for bolt qualities 5.6, 6.8, 8.8 or 12.9 or customer specific designs and dimensions.


Thread projection
The minimum required thread projection of the bolt above the nut: 1,0 x d of the bolt (depending on the preload force). If there is not enough thread projection ITH recommends the use of ITH tension nuts.
