Got any specialty fasteners you like to work with or some type of bolt or nut you use as an upgrade? Something that increases the clamping load of the original fastener? something, stronger, more corrosion resistant or some other improved property compared to common fasteners? Need advise on an upgrade or replacement for a fastener that failed?
Post it here. Preferably with pics, size, material properties, and purpose of the fastener you have /need.
I'll start with an easy one.
OEM mild steel timing peg upgraded to dog point hexagon socket head stud with self locking nut. Both sourced from Metric & Multi Standard. The stud is rated 14.9 (that's right- 14.9 and not 12.9) and has a Vicker hardness of 45. Purpose of the upgrade is to prevent having to disassemble the whole bottom end of the engine in case you bend the bolt while you lean on it with one of the crankshaft counterweights during tighteting of the crank pulley. This stud will shear off cleanly in half, if at all, instead of bending.
Bending test ---> Pass.
