Big E Convection Blower metal screws

[Tony K]

Convection blower has been vibrating a little recently and tried to tighten the screws but they won't tighten up anymore. Any suggestions or tricks people use to help screws tighten up? Have heard of wrapping the screw with string but not sure thats a good idea around heat! Stoves a good 10 years plus old. Thoughts on using Loctite? Thanks

If they are sheet metal screws,go to next larger size.What should be in there is nutserts/keenserts but production costs prohibit this.Mke shure you don't need a new blower-too much vibration.
