Stainless Steel Machine Screws

Stainless steel machine screws are optimal for fastening machine components. They are well-suited to corrosive environments and offer a great range of temperature resistance. The uniform diameter of the shaft makes these threaded stainless steel fasteners appear similar to bolts. However, unlike bolts, they can be used with or without an accompanying nut.

BW Industrial Sales is your industrial supplier for any bulk stainless steel fastener need. We carry a massive selection of fully threaded stainless steel machine screws that are ready to ship. Our inventory includes a wide range of head and drive types, cuts, and combinations.

Stainless Steel Alloys for Industrial Machine Screws

Our stainless steel machine screws are available in a variety of stainless steel alloy materials. An optional black oxide coating is also available. Our in-stock alloys include:
  • 18-8: This alloy is 18% chromium and 8% nickel. It features superior corrosion resistance. It is a budget-friendly option with impressive yield strength.
  • 316: 316 stainless steel features high tensile strength and can easily withstand harsh environments, including saltwater and marine applications.
  • 410: This SS machine screw alloy is an excellent general-purpose choice with heightened corrosion resistance, high strength, and durability.
  • A2: A2 alloy is the most common stainless steel fastener material. It is a cost-effective solution found in many household appliances and products.
  • A4: A4 alloy is similar to A2. However, it has heightened corrosion resistance and is the standard choice for many industrial applications.
