Cold-rolled spindle

The spindles are engineered with precision cold-rolled threads — over 40% stronger than conventional cut threads and exceptionally smooth in operation. 
Paired with a specially designed double nylon support nut, they deliver outstanding reliability and minimal wear thanks to reduced friction.
This proven durability is backed by our confidence: every AUTOPSTENHOJ spindle and nut set comes with a 3-year warranty, that is extended to 5-year warranty when paired with a maintenance contract from a certified distributor. 
Strength, reliability, and peace of mind — built in.
