Product Details
The Honda OEM K-Series Engine Mount Stud Bolt is a genuine factory replacement designed to secure the engine mounting bracket assembly on select Honda and Acura K-series engines. This essential mounting fastener provides the proper connection between the engine mount and its corresponding mounting bracket, helping maintain secure engine positioning during normal vehicle operation.
Featuring an M12 x 1.25 thread pitch and 91mm length, this genuine Honda stud is manufactured to the original factory specifications for proper fitment and dependable performance.

Shipping was faster then expected, with all of the high torque, hp and VTAK that my stock 2003 base FWD CRV puts out, the old engine mount stud broke. I had to get a new replacement, thanks to Kseries parts I was able to get what I needed. K series parts.com rocks.

K- Series was only place I could find this bolt. But after ordering i'm use it as a spare because I ended up having to buy the whole part that bolt went into and it came with the bolt
