Original BMW Camshaft Adapter Torx Bolt M10x35 for BMW E30 325 Models, E28 528e, and E34 525i (1982–1993)

Original BMW 11-31-1-715-412 is the M10x35 Torx bolt that secures the camshaft adapter on the M20 engine in the BMW E30 325 models, the E28 528e, and the E34 525i (1982–1993). BMW calls it simply a Torx bolt and places it with the cylinder head and camshaft hardware. The camshaft controls when the valves open and close, so every fastener in its drive has to hold its clamping load each time the engine runs. A Torx head uses a six-lobe drive that takes more tightening force than a Phillips recess before the tool slips. The bolt weighs 24 grams (0.85 oz) and is made in Germany. It arrives brand new and unused.

Original BMW Parts carry a 24-month parts warranty.

BMW uses one bolt number across these three chassis, so a 325iX and a 528e take the same part.
