Original BMW Engine Mount Torx Bolt M8 x 33 for BMW 2 Series, 3 Series, and 4 Series (2012–2021)

Measuring M8 x 33 mm in strength class 8.8, this Original BMW Torx bolt fastens the engine mount on the BMW 2 Series, 3 Series, and 4 Series built from 2012 through 2021. BMW designates it M8X33-8.8-ZNS3: an M8 thread, a 33 mm length, the 8.8 strength class, and BMW's ZNS3 finish code. Each bolt weighs about 19 grams and is sold and priced individually. BMW's parts data shows production from July 2011, and the bolt is made in Italy. Engine mount bolts clamp the mount between the engine and the chassis, so they carry the engine's weight and its torque reaction every time the car pulls away.

Original BMW Parts carry a 24-month parts warranty.
