Mc master is semi expansive, best price I used to get was from Lawson supply. I typically only buy grade 8, or 12.9 fastenal is just expensive. Case in point. We needed a few metric bolts for my brother Nissan rear k member. Called Nissan $8.00 a bolt. Stopped by fastenal. They had the bolts that would work for $6.50 each, but we needed to buy a 10 pack, and washers, 25 pack. Till all the bs was added up it was more then going to the dealer. That's where fastenal gets you at. And if they (my local store) has to order something in for you it seems it's always a 25 or 50 count pack that they want you to buy. Just what been my experience with them.
