Customer Questions

Question:

why are these bolts 14mm long when the ones in the engine are only 10mm long? - Damon

Answer:

Hi Damon, with countersunk screws, the depth of the head is included in the measurement. The head is about 4mm depth, and the threads are 10mm, making the overall length about 14mm, which is the same as stock.

Question:

hey guys, what size allen wrench for this? - Joshua

Answer:

Hey Joshua, it is a 4mm allen key.

Question:

What is the torque spec for these screws? - Don Mendell

Answer:

Hi Don, Nissan doesn't have a stated torque spec, we usually recommend about 10-12 ft-lbs.

I stripped them while I was using a torque wrench that was brand new I only stripped half of them though other half was fine my guess is because I used blue lock tight on half of them I suggest adding a warning to not do that
