Galvanized locking nuts for turnbuckles can be purchased from marine supply (
not sailboat!) wholesalers, typically supplied in pairs (a left hand and a
right hand nut). It can be difficult to purchase small quantities from
wholesale suppliers if you're not a regular customer.
Someone recommended McMaster-Carr; however, their left hand threaded nuts are
plated and will not fit over galvanized turnbuckle threads.
My recommendation is that you stick with the standard practice in the T O W E
R industry: use a safety wire in a figure 8 configuration. Turnbuckle
locknuts are not a generally accepted solution in the tower industry.
