Quick Torque Wrench Q

Question
How many people actually tighten the sump plug/oil drain bolt to 21 N-m. Sounds quite high to me. I don't.

Ehhh. Me? I think? Sounds needlessly high. Especially when you think what happens if that bolt goes byebye.

i think my spark plugs (25mn) is excessively tight, so i do them about 12, thats one thread i really dont want to be stripping.

oil sump goes on hand tight, + a teeny bit more.

Especially with the Sv not having a seperate sump pan.

sdusk , you are right about the bolts elasticity and wot not but the case of the sump plug shows damage can be caused if we get too obsessed with the torque figures in the manual/torque wrences. I use to be that way but now but no more.

I do mine more or less the same as warren. Hand tight and a quarter to half a turn. I do though put a blob of silicon sealant(outside) as belts and braces.

That's not correct... The Halfords ones, or at least the 3/8 ones, are reversble, just not conveniently- you need to remove the head and put it through from the other side.

ive read that your not supposed to use a torque wrench for removal of bolts, only for tightening.

not sure how true this is though, and if it is, why give an option of a reversable head ?

Northwind, I hope the 1/2" Halford wrench is as well - it would show that it is always worthwhile reading the instructions!

Not talking about undoing, but tightening of reverse or left hand threads.

Yeah, think so- looks to be the same design, though I've only got the low-value one.
