Again and again we are confronted with questions about the differences between Torx®, 6-Lobe and iso 10664 confronted.

6-Lobe: The license-free drive
6-Lobe is nothing else than an unprotected and license-free name for Torx®. The dimensional similarity to Torx® is 100%. The use of 6-Lobe gauges instead of
Torx® gauges must always be checked against the company's internal regulations.

which is commonly known as Hexagon socket is commonly referred to. Basically one can claim that when a medical technology manufacturer speaks of Torx® products
speaks of Torx® products, there is a mistake. In medical technology, the iso 10664 standard has become established. There again in the meantime innumerable special versions or with in-house tolerance limits.
