Review on High-Quality Hillman 370054 Toggle 16X3 Inch 50 Pack: Versatile & Durable Fasteners for All Projects by David Bartan

if you compare these toggles to a 20-30 year old bolt you would quickly see how cheap they are and what a piece of junk they are like foil compared to an old heavy switch from steel. You have to be careful not to overtighten them or they will break. Old school switches are much more durable, look for vintage star or lever switches on ebay than buy them
