I also am a customer of MxMaster Carr and have been so for many years. I buy hardware and raw materials such as rubber, plastics, metals, sheet and solid teflon, shim stock along with other goodies that allow me to complete my little projects. With fast service, detailed information about their products, and no ridiculous minimum purchase requirements, they’re my favorite supplier of hardware and materials. I often get one day service without paying for speedy shipping.
