Torque specifications*

Ft-lbs (unless otherwise indicated)
Note:
One foot-pound (ft-lb) of torque is equivalent to 12 inch-pounds (in-lbs) of torque. Torque values below approximately 15 ft-lbs are expressed in inch-pounds, since most foot-pound torque wrenches are not accurate at these smaller values.

Lol, this is prob true

 

If any of you guys want any more torque specs let me know.

 

I thought the ol' german way of torqueing was good enough. You know Gudentaht?

 

Haha a lil bit. From my fathers side.
