In order to design the nut thread for dynamic and static stresses, a first thread length (9) consists of a compacted thread material and a second thread length (10) consists of an uncompacted thread material.

The double threads provide additional thread length while allowing the tip to be quickly unthreaded for quick tip changes in use.

The recommended thread length should exceed the dimensions of the building level itself.

At 750mm in length and with a 32mm diameter and an unravelled thread length of 2.3m the replacement bolts are by far the largest physical project Technifast has undertaken.

In order to design the nut thread for dynamic and static stresses, a first thread length (9) consists of a compacted thread material and a second thread length (10) consists of an uncompacted thread material.

The length of the internal thread (5) is greater than the minimum penetration depth of the tension rod.

The pitch of the thread is greater than the length of the thread.

The total, projected length of the cutting edge (30) is smaller than two thread pitches.

Furthermore, a total length of the grooves 3 and 4 along the above-mentioned genetatrics (taking into account the width of the roots of the screw thread) does not exceed the length of the screw thread of the nipple end 1 in the same direction.

The length of the external thread (9) on the tension rod (8) is substantially the same as the minimum penetration depth of the tension rod plus the length of one tolerance compensation section.

The threaded connection is used to provide a spring operated adjustment of the length.
