Undated handout image released by Arnold Umformtechnik on 22 April 2008 shows Alufast(C) aluminium screws from Arnold Umformtechnik. The increasing importance of magnesium as a construction material requires an inspired pairing of materials when it comes to screw fastenings. Alufast aluminium screws from Arnold Umformtechnik have proved to be particularly excellent for making screw fastenings on housing sections, brackets and stiffeners made of magnesium. The approximately 350 gram weight advantage over steel versions means that Alufast screws are of interest to design engineers working in many fields, including gearbox design. An investigation carried out by fastener specialists Arnold Umformtechnik GmbH found that this was the weight saving that could be made in a gearbox containing 20 screws. In terms of annual production of, say 100,000 gear boxes, that would translate to a saving of some 35 tons of steel. EPA/ARNOLD UMFORMTECHNIK EPA COMMERCIAL FEED EDITORIAL USE onLY
