I’m really happy I discovered Blacksmith Bolt. I repair stringed instruments and one of the common repairs is tuning machines. They nearly always have missing screws, typically oval and round heads that hold the machines in place. I’ve been able to replace them with screws obtained from Blacksmith Bolt. They match the missing originals very closely and that they are nickel plated like the originals is even better. They’re quick at delivery and have shipped what I’ve wanted with no mistakes. I recommend them highly!
