Keeping a bolt tight in a hot frying pan



That's the problem. Lovely non-stick frying pan, but the handle loosens frequently. Wife got a replacement for the stove, but wants to keep this one for baking. So, removed the handle. It was not as I thought, a problem from a steel machine screw going into an aluminum pan. There is a steel bracket that the screw threads into. And there is a split washer on the screw, but it seems to be to have gotten flattened. While the pan doesn't get really hot, it does, apparently, get hot enough to remove any temper in that split washer. So, my question, does anyone know if there are split washers or the like, made for a "high" temperature environment? This is right now purely for information. Unless she buys another pan, it is of purely intellectual interest.

:-) I've been married for nearly 50 years and all that time I've been tightening handles on cooking pots :-)

K & R make high temperature lock washers

You need a "star" lockwasher instead of a "split" lockwasher and a slightly deformed thread helps too - NOT deformed at "the tip" but about 3 threads from "tight"

temperature and differential expoansion that allows them to back off. The "belleville" type I believe they call them, is a "pretensioning spring".

The bolts through this Zytel nylon bracket kept loosening until I drilled and safety wired their heads.

The wire is just loosely bent so it doesn't shake out, not twisted together, and it's kept the pump and motor bolts tight for over 20 yrs.

Generally speaking a internal ar double star washer was the washer of choice for good cookwear
