Thread-forming screw | Zinc-plated | DIN 7500
Thread-forming flat head screw, large countersunk head Torx in FZB is intended for use in metallic materials where threads are formed directly into the material. The product meets DIN 7500 and is used where chip-free thread forming and high joint security are required. It is suitable for professional installations where repeatable assembly and controlled friction are essential. The Gleitmo 615 coating enables a stable tightening torque and reduces the risk of galling.
APPLICATION AREA
The product is used in industrial assembly and manufacturing. It is intended for applications where an internal thread is formed directly into the material without chip formation and where surface treatment and lubricant coating provide controlled friction and corrosion protection.

FREQUENTLY ASKED QUESTIONS (FAQ)
What does thread-forming screw according to DIN 7500 mean?
A thread-forming screw forms the internal thread in the material during assembly without cutting chips. This provides high strength and reduces the need for pre-tapping.
What is the advantage of a Taptite II thread?
Taptite II has a trilobular geometry that reduces friction during installation and provides stable tightening torque as well as improved locking in the material.
What is the function of the Gleitmo 615 coating?
Gleitmo 615 is a lubricating coating that reduces friction during assembly, which provides more consistent torque and reduces the risk of cold welding.
When is a large countersunk head used?
A large countersunk head is used when the load needs to be distributed over a larger surface area while keeping the screw flush with the surface after assembly.
