Bought these hoping they would fit my Shimano FC5500 using Octalink BB5500 Bottom Bracket. FC5600, 6600, and 7700 (i think) all use a similar lock bolt. Worked perfectly, didn't have to spend 60$ on a pair of NOS locking bolts

I have a 2019 Vitus Nucleus 27 VRS that came with a SR suntour crank and I’m almost certain that the bike came missing the bolt on the left side of the crank but I never had any problems with it until it came off recently. I tried about 4 different sizes before finding this one and it fit! Finally! I torqued it down to 25 foot pounds and I’m good to go! Ready for the trails again! I hadn’t ridden my bike in months being I didn’t want to break something.
