Bulten Stainless offers a complete range of stainless and acid-proof fasteners. Bulten Stainless manufactures both standard and special products in two modern plants. Both plants have high capacity and are well equipped for the accurate precision required for manufacturing high-quality stainless steel, acid proof fasteners. Our customers can see our origins reflected to this day – Bulten Stainless has long led the way in developing stainless and acid-proof fasteners. Bulten Stainless is a driving force behind the development of products with ever improving properties. For many years we have manufactured fasteners which "don’t exist" – i.e. products whose durability far exceeds established standards. Thanks to our close relations and contact with world-beating specialist companies, Bulten Stainless has early access to information on new types of steel. Bulten Stainless offers a complete range of stainless and acid-proof fasteners. We promise to employ all our service skills and expertise in finding a solution which suits you, whether it’s large or small, manufactured in-house in Sweden or purchased from around the world, specialist or standard. This enables us to achieve our ambition of being your one and only supplier of fasteners. For a long time, Bulten Stainless has dominated the development of high-strength fasteners made from corrosion-resistant steel. Now we proudly present BUMAX 88 AND BUMAX 109 – the best yet. BUMAX 88 and 109 are fasteners having unique properties, enabling to move the limits ahead regarding strength, weight, corrosion resistance and total economy. The BUMAX products can also give top performance long after standard fasteners have reached their limits. The difference compared to conventional products is especially noticeable in extreme environments. With its Bumax range, Bulten Stainless has further reinforced its position as the leading developer of high-strength, stainless fasteners. The latest addition to the range is Bumax Hard – a group of acid-proof, self-tapping screws which can simply form threads in the same way as equivalent hardened carbon steel screws. The Bumax Hard self-tapping screw is suitable for fitting to sheet metal and profiles in Carbon steel. It can also work in stainless or acid-proof thin plate where the plate thickness is equal to or less than the thread pitch. The Bumax Hard Taptite is excellent for fitting to sheet metal and profiles of carbon steel and stainless/acid-proof steel – the surface-treated version can work in material hardness up to approx. 200 H. Bumax Lock is an all-metal lock nut. It is equipped with a specially designed thread profi le that locks when it is tightened, distributing the tensile stress along the entire nut thread. This allows better load distribution, which in turn produces greater gripping strength. Bulten Stainless is one of a few companies in the fastener business to be certified to ISO 9001:2000. This is the latest, most modern version of quality certification.
