Two of my L250 upper midrange (LE5-11) bolts (calling them bolts since they thread into t-nuts - maybe more conventional to call them screws?) have messed up threads, as I was surprised to discover when removing my upper midranges.

Hoping I can chase them with a die to clean them up for re-installation. Forgive my laziness, I thought I would ask here first as to what the thread spec is. I'm assuming it's a standard size?

Or, if replacements are readily available, I'd love to know.

Thanks in advance,
Ryan
