Google the part number - I've bought a handful of some fairly trick 
Hi-shear fasteners from www.hardwareinc.net, 405-787-1088 in Oklahoma, 
he sells onesy-twoseys.

They were for the outboard landing gear seat on my C150, I recall they 
were something like $1.16 each, I needed 19. No problem, he sent them on 
the honor system!

They installed with a ratchet that has a hole through it for an Allen 
key (holds the fastener from turning), the nut has a groove in it, and 
the hex breaks off when you reach the correct torque. ("Hey, ya know, 
all the heads came off the nuts you sold me!")

You DO need the part number because you would not believe all the 
trick/exotic/neverseenoneofthose fasteners used on airplanes sometimes. 
Ever seen a tri-wing fastener? Looks like a Phillips, except only three 
legs - available in titanium, stainless, unobtanium, close tolerance, 
you name it, priced accordingly. Holds 747s together - does a good job, too.
