STERLING HEIGHTS, Mich. (July 15, 2008) – Acument North America has introduced a thread forming insert for magnesium automotive components that allows machine screws to be applied at final assembly and later removed and reinstalled for servicing.

The new MaggCert™ threaded insert for magnesium bypasses the need for hole tapping operations, minimizes debris generation during installation, virtually eliminates serviceability problems caused by galvanic corrosion, and adds the strength of hardened steel threading to this lightweight material.

“OEMS and suppliers are using increasing amounts of magnesium to help drive down the weight of cars and trucks, but at the same time must retain the ability to remove and service parts made from this low ductility material,” said David Goss, principal engineer for Acument North America.

“MaggCert threaded inserts deliver the solution, combining high mechanical strength and quick removal and reinsertion of screws, without serious concerns over galvanic corrosion. They provide a securely anchored joint and establish a fastening point for standard machine screws.”

MaggCert steel inserts have the same broad flank angle as Acument Mag-Form® thread forming screws, compressing rather than roll forming threads into die-cast magnesium. The Mag-Form design eliminates thread fractures while decreasing shear stress.

MaggCert external threads and machine screw internal threads are packaged into a thin head design installed by an Acument Torx Plus® drive bit, elliptically shaped to broaden contact surfaces while maximizing driver engagement and torque transfer. A zero degree drive angle eliminates radial stresses and straight sidewalls prevent camout.

Potential MaggCert applications include magnesium engine blocks, radiator supports, valve and cam covers, transmission casings, fuel storage tanks, seat frames, instrument panel and bumper support beams, and airbag housings. They are made from heat treated, low carbon steel, and offered in sizes M4 through M10.
