Toffee Apple bolts

and if anyone ever needs to use a 12.9 metric bolt, better off using an Unbrako or Holo Krome socket head cap screw (allen bolt) as their heat treatment and material is so far superior to most all industrial hex head bolts.

In critical situations needing a Grade 5 SAE/Imperial size, try and source an AN airframe bolt for the above reasons.

Hard to torque without proper device though.. I might give the 8.8's a go all round
