  • Can stainless steel fasteners be used at very low and very high temperatures?

    Yes. Stainless steel fasteners have excellent properties at both extremes of the temperature scale; it can be used down to liquid nitrogen temperatures and up to about 1800° F.

  • What is "passivation" finish on stainless steel fasteners?

    When the amount of chromium (in an iron matrix) exceeds 10 ½%, a complex chrome oxide forms instantaneously that prevents the further diffusion of oxygen into the surface and results in the “passive” nature of stainless steel and its resistance to oxidation (or corrosion). A chemical "dip" into 10% nitric acid plus 2% hydrofluoric acid bath will enhance the development of this "passive" oxide.

  • Can stainless steel fasteners rust? Why? (I thought stainless did not rust!)

    Stainless does not “rust” as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface. If the iron is embedded in the surface, you can try a solution of 10% nitric and 2% hydrofluoric acid at room temperature or slightly heated. Wash area well with lots and lots of water after use. Commercially available “pickling paste” can also be used.

  • What is the difference between 18/8 and 18/10 stainless steel fasteners?

    The first number is the amount of chromium that is contained in the alloy, i.e., 18 is 18% chromium. The second number is the amount of nickel, i.e., 8 stands for 8% nickel. So 18/8 means that this stainless steel contains 18% chromium and 8% nickel. 18/10 is 18% chromium and 10% nickel. The higher the numbers the more corrosion resistant the material.

    Note that 18/0 is a misleading designation. Both 18/8 and 18/10 contain nickel and are part of the grade family “300 series” stainless. 18/0 means that there is 18% chromium but zero nickel. When there is no nickel the stainless grade family is the “400 series”. 400 series stainless steel fasteners are not as corrosion resistant as the 300 series and are magnetic, where the 300 series are non-magnetic.

  • What makes stainless steel fasteners stainless?

    Stainless steel fasteners must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless steel fasteners and materials.

  • What materials can I have bolts, metal screws and other fasteners made of?

    We have fixings in the following materials:

    • Steel
    • Low carbon steel
    • Medium carbon steel
    • High carbon steel
    • Alloy steels
    • 18-8/304, 316 and 410 stainless steel
    • Structural steel
    • Aluminium
    • Brass
    • Bronze
    • Nickel copper
    • Silicon bronze
    • Titanium
    • And other special alloys
  • What finishes are available for your metal screws and fasteners?

    Sourced both from overseas and Australia, our fasteners are made of a variety of raw materials with a broad range of finishes. Most finishes are applied to bolts, metal screws and fasteners to enhance the corrosion resistance. We also provide plating as required. Many standard platings are available, including:

    • Zinc
    • Zinc trivalent
    • Zinc yellow
    • Zinc black
    • Antique brass
    • Nickel
    • Tin
    • Black oxide
    • Phosphate
    • Oil
    • And many other decorative finishes

    We can also provide special and standard colours of painting and powder coating for bolts and metal screws which are perfect for special applications.

  • I am looking to have products delivered to a sub-supplier or secondary operation elsewhere in Australia. Can fasteners be drop shipped directly for me?

    Yes we can! We will gladly ship bolts, metal screws, fasteners, abrasives, hardware and other products on your behalf directly to any destination around Australia. Fasteners can be shipped with your name and any other important details on all of the printed documents sent if you specifically let us know.

  • We need specially-packaged bolts, metal screws, other fasteners and tools. Can you do that?
