A quality AN Bolt. Looks and works as it should. I buy from Spruce because of their reputation for quality. In Aircraft training was taught the horror stories of lives lost due to failed scaffolding caused by cheap, counterfeit, imported AN bolts. I was trained the best way to assure quality AN hardware was to only buy from trusted aviation suppliers.

It depends on the application, but both .032 and .041 will fit through the hole.
Per the Tech Data Sheet, the hole location is determined from the start of the threads, on the head side, to the center of the drilled hole. AN3 = 17/64", AN4 = 5/16", AN5 = 23/64", AN6 = 7/16", AN7 = 31/64", AN8 = 39/64".
Stainless bolts are corrosion resistant for applications where corrosion is a problem. CAD plated bolts are made of steel with CAD plating to help surface corrosion, but it can been worn or chipped off.
The nominal length is the length from under the head to the end of the shank.

It is drilled for 1/16" cotter pin so it will be slightly larger than 1/16".
