How can they make money doing that?

Next time he’ll buy $20 worth of bolts and pay $80.

  • What's a good place for well priced bolts if I'm not worried about next day shipping but need them to not be made of pot metal?

    • Where are you finding pot metal bolts? Your best option should be anything from Ace/Home Depot/Lowes. The matte finish ones are zinc galvanized, that’s just the protective coating. They are made of carbon steel and are graded according to standards set by organizations like SAE.

      Hardware stores will have grade 2 bolts for the most part (or the metric equivalents). These will be made with weaker steel and will be cut instead of cold rolled. If you’re doing something that needs more strength than that, you can get grade 5 or 8 bolts. These will be cold rolled from higher strength steel and may be tested with a penetrant dye to check for any fractures. You can get those at a hardware store or at many online stores. If you need more strength than that, you’re probably in an aerospace application and I recommend that you don’t ask for advice on HN.

      If you’re buying a shit-load of bolts (like, more than a thousand of one kind of bolt), then you can go to a wholesale website.

    • Call a local machine shop, mechanic or welder and ask. Almost every town and city has a store that specializes in hardware for tradies that has better pricing and selection than HD or Ace or homeowner stores.

    • Fastenal is good for wholesale, and if you're lucky enough to have a location closeby, you can have it next day or even same day.

    • My go-to for stuff like this used to be SmallParts.com back when McMaster-Carr wouldn't sell to individuals (they do now). Amazon bought Small Parts and renamed it Amazon Supply. I haven't bought anything from them recently, but it's worth a shot.

      Small Parts was amazing they specialized in, you got it, small components such as fasteners (you could get titanium screws if you needed them), small mechanicals such as tubing, solenoid valves, bearings, shafting, metal, etc. They were a prototyper's dream.

Most orders pay full cost of shipping. This was an atypical experience.

No idea. I talked with the truck driver, and he said we was being paid way more than $8 for the delivery. I used my company account, so I guess they're willing to take a loss on some orders and make it up on others.
