Manufacturing Technology

With more than 70 years of experience HEROSLAM S.A.L has established itself as a manufacturer of top quality and long life thread rolling tools for the fastener industry.

The Spanish manufacturer says it is able to offer a complete range of high performance tools of exceptional quality including flat and planetary dies, as well as cylindrical thread rolling dies. All of HEROSLAM’s flat dies are made using a grinding process, thus meeting the highest standards in profile quality and precision, and guaranteeing an excellent tool performance. This, in combination with its in-house coating facilities, enables the company to offer long life tools for the most demanding applications such as thread rolling tempered parts in grades 10.9, 12.9 and 15.9.

HEROSLAM also manufactures a wide range of cylindrical dies (2 or 3 dies per set), which offer multiple possibilities and advantages for thread rolling very hard materials or large size trapezoidal profiles with greater precision and quality.

The company’s planetary thread rolling dies offer customers significant economic advantages. Depending on each application, HEROSLAM can manufacture planetary dies in different materials – making unique tools that are more durable and offer higher performance. It can also manufacture planetary dies for different applications such as U-bolts, nails, as well as for MAThread® and Taptite® fasteners.

In addition to standard dies, the company can also provide special dies for ogival fasteners, aerospace fasteners, as well as knurling, grooving and straightening applications. Other services include customised coatings made in-house, a tool regrinding service and first-class technical support.
