Applications
Direct fastening in ultra-high-strength materials
The MAXXtip® screw extends the possibilities of direct fastening by combining a bainitic load-bearing screw shaft with an ultra-hard thread-forming tip. With that, direct fastening can be expanded safely to materials like high- and ultra-high-strength steels as well as cast steel. The very high hardness of the tip secures reliable thread forming, while the bainitic microstructure is resistant when it comes to hydrogen embrittlement. The result: reduced number of process steps, safe assembly in materials with tensile strengths up to 1500 MPa, and sustainable, removable fastening solutions. -
Overview

Thread forming solution for (ultra) high strength materials
EJOT MAXXtip® combines a carbo-austempered shank with an ultra hard screw tip. This unique combination allows completely new options for direct fastening into (ultra) high strength materials.
Due to the carbo-austempered microstructure (strength similar to 10.9) in the load-bearing area MAXXtip® screws are insensitive to hydrogen embrittlement. Therefore, galvanic surfaces can be applied without tempering leading to a thread flank hardness of at least 750 HV* in the forming area.
*In case of Zn flake surfaces, baking leads to a reduced thread flank hardness in the forming area of at least 600 HV.
Main application fields of EJOT MAXXtip®
(ultra) high strength steel sheets (at least UTS of 1200 MPa) using the thread types
- SHEETtracs® up to 2 mm
- Spiralform® analogous to DIN 7500
cast iron (GJS und GJL) using the Spiralform® thread type
