The issue of the quality of threaded rods
We would like to draw your attention to the fact that low-quality threaded rods are appearing on our market, and their use is associated with problems and risks. Thanks to the change of the thread profile outside the tolerance, the manufacturer saves on the weight of the input material. Our company does not go in this direction and supplies our customers with quality according to applicable standards.
The issue low-quality threaded rods
- at a significantly lower load than prescribed, the bars will tear
- at a significantly lower load than prescribed, the thread will tear off
- repeated loosening and tightening will cause the thread to tear off
Quick check of rods
- large clearance between nut and threaded rod
- visual inspection of the thread – sharp top angle of the thread and sparse thread profile
- weight verification on the exact length and comparison with our table of minimum weights
