Thread rolling dies for aerospace fasteners

Flat and cylindrical dies for aerospace fasteners
Heroslam is a worldwide reference in the design and manufacturing of special thread rolling dies for the production of aerospace fasteners. Proof of it is that the most recognized aerospace fastener manufacturers worldwide rely on Heroslam as their main thread rolling tools supplier.

Quality and precision
Thread profiles of top quality and precision thanks to our advanced grinding technology, achieving a reliable and stable threading process, guaranteeing high precision threads and minimizing quality problems on the final part.

Chamfers and RRO technology
Special and customized chamfers and RRO (Radiused Root Runout) that improve the thread quality and resistance on the final part. Our self-developed RRO technology also increases tool life by minimizing chipping problems on the rolling dies.

Steel and coatings
Thanks to our advanced grinding technology and our special steels and coatings, we produce high performance and long life flat and cylindrical thread rolling dies for the production of aerospace fasteners made of hard to roll materials such as titanium, Inconel, etc.
