Also, threads formed in this manner are free without clearance and self-locking. Consequently, additional chemical adhesives are redundant. The thread is a metric ISO thread which indicates the compatibility with standard norm parts.
The material of the component is an important parameter that must be considered in practice. Thread-forming screws are applicable for all ductile materials. If this condition is not met (components made of gray iron) the direct-screwing technology is not recommended.
