About McMaster-Carr

McMaster-Carr supplies parts and materials for factories, maintenance teams, engineers and other businesses, as well as individual buyers. Its range covers fasteners, tools, pipe fittings, motors, raw materials, safety supplies and many other items, with detailed product specifications and CAD drawings for many parts. The company is listed in the United States, and its mcmaster.com domain was registered in 1994. The site publishes shipping, contact, returns, careers, help, terms and privacy pages, and it lists both a phone number and an email address. When ordering technical parts, match exact specifications, such as thread size, material grade, pressure or temperature rating, rather than relying on a part name. Download the drawing or data sheet if one is available and check it against your application. Look at shipping options and costs for heavy or oversized items, since freight can add a lot. Read the return conditions for cut-to-size or special-order items, which may not be returnable. For safety-critical uses, confirm that the part meets the relevant standard or certification your project requires.
