Pozostale sruby trzymaja, ale ze dwie udalo mi sie troche dokrecic. a szkoda bo są po 80zł :) Smaruje i nie znikają tyle, że mam klucz dyn to nie odpadają łebki 110 Nm łatwo przeroczyć nie mówiąc o tych co stają na kluczu. -- Piter Sweet little girl I prefer You behind the wheel Me the passenger |

Usually, that spec is for clean, dry threads, although I don't know if that is true for every type of car - check your manual. The purpose of tightening a fastener is to introduce preload into the shank of the fastener, and corresponding compression into the joint members. This combined system then protects the shank of the bolt from enduring the full applied load. Typically, a properly preloaded bolt only sees 20% of any applied load. Properly preloaded is the important part - not excessive, nor insufficient preload - the correct preload. Technically, by reducing the friction between the nut and thread you put more preload in the shank of the fastener per unit torque than for a dry set up. This reduces the margin between the operating preload and the yield preload for the fastener. i.e., it makes overload of the fastener more likely. https://www.honestjohn.co.uk/forum/post/index.htm?t=33033 -- Piter Sweet little girl I prefer You behind the wheel Me the passenger |
