Kim Prout showed me a good one. A company called Stage 8 in CA make locking
safety bolts. Simple and look nice. The hex head of the bolt, (they do nuts
too I believe) has a circlip groove part way up from the bearing face. A
washer with a tongue and a hex hole slips over the bolt head and is locked
in place with a circlip. The tongue works like a spanner and prevents the
bolt from turning. I plan to fit a set at our next check.
Stage 8, San Rafael, CA 94901, phone 415 485 5340 or 800 843 7836
