Original BMW Drive Belt Tensioner Bolt M10x90 for BMW 2, 3, 4, 5, 6, 7 Series, M2, M3, M4, X3, X4, X5, and X6 (2010–2021)

Part number 07-12-9-906-293 is the Original BMW M10x90 ASA bolt that fastens the drive belt tensioner to the engine block on N55 and S55 powered BMW models from 2010 to 2021. BMW names it ASA-Bolt, size M10x90, and gives it the finish designation ZNNIV SI. It weighs 55 g (0.1 lb), is made in Germany, and is sold individually. BMW production of this number began in September 2009. The belt tensioner holds steady pressure on the accessory drive belt, and this long bolt carries that load into the block.

Original BMW Parts carry a 24-month parts warranty.

BMW's service procedure does not call for replacing this bolt when the tensioner comes off. Replacing it still makes sense if the E-Torx head shows any deformation or the threads are corroded, since a rounded head or rough thread makes the next removal and installation harder. BMW specifies this bolt for the N55 and S55 applications in this fitment.
