Edelstahlschrauben und Verbindungselemente

In addition to forged eyebolts and ringnuts according to DIN 580/582, there are now also more economically priced variants.

Lederer expands DIN 580/582 assortment

18.11.2014

As a well-known specialist of several decades’ standing in the field of stainless steel fasteners, screws and nuts, Lederer is expanding its assortment in the area of eyebolts and ring nuts manufactured in accordance with DIN 580/582. As a supplement to the variant forged in the die, Lederer is now also offering the casted version.

Production using the lost wax procedure gives the eyebolts and ring nuts their casting-typical, smooth and polished surface that is suitable in particular for tasks of a more decorative nature than those of the forged variety. In addition, casted eyebolts and ring nuts can be manufactured far more economically. All of the load values required in the norm are virtually fulfilled; in this way, the casted variants can be deployed for light lifting and transporting activities and for eye fastening, too. However, they may not be used in safety-relevant areas; instead, the forged version must be used in those areas.

The available assortment covers the sizes M6-M42 (forged), M5-M16 (casted) and the material variants stainless steel A2 and A4.
