Torque tips

Post by BAbycoat »

My travels take me to Bukit Keteri in Malaysia this coming week - and I read an online review that it has "numbers of loose bolts". Optimistically assuming that only the nuts are loose (and not wanting to start a discussion on David Lama's bolting ethics), we'll take a few 17mm ring spanners.

Given the potential for SCC, I don't want to over-tighten the bolts. We won't have a torque wrench. Can anyone suggest rules-of-thumb as to how tight is tight enough?

Is there a reason why no one uses nylock nuts when bolting routes? Because nylock nuts wont work themselves loose.

There is no reason why you can't use nylocks (I would say) As long as they are made of the same stainless steel grade. Ive always thought, that if I ever got to bolt something I would use locktight, burr the thread of nut and bolt once its tightened or even hacksaw down the centre of the bolt head and wedge the two halfs slighly open. Locktight just seems to be the least effort and fail safe.

Loctite is great! In some circumstances however you should remember that lock tite removal in the industry is done by heating the bolt/ nut & then the loctite loosens - so in some cases cyclic heating will have the same effect.

Nyloc nuts on the other hand give you the opportunity to tighten to just the right torque & KNOW that the nut will not work loose. Its a bit of a no brainer apart from the cost. The same material is a great idea as there is no chance of galvanic corrosion - which could take place if you used a plated bolt and a stainless hanger or vice versa, but should be ok with different grades of stainless. Galvanic corrosion will take place in a seaside environment if the materials are dissimilar. Though this may seem like a wild herring chase it is just as likely as Stress corrosion if you use different materials.
