Almost everything we manufacture, large diameter or small, is custom. Whether we are making a standard product that our customers cannot find or a hard-to-source custom bolt and fastener, Big Bolt has you covered. We have even worked with customers for custom bolts and fasteners in the marine industry. Customers come to Big Bolt for make to print or "Blue Print Specials." We can custom manufacture to your specification and hold very tight tolerances. Big Bolt also is capable of providing a PPAP for start up projects and many other required certifications. We offer a broad range of material types – over 250 to be exact. Our in-house capabilities, including a broad range of secondary operations, make Big Bolt the go-to supplier for all your specialty fastener requirements.
