ADVERTORIAL | SFS INTEC STEELTOSTEEL FIXING GOES NUTFREE DECEMBER 2017 | BUILDING PRODUCTS 47 The new TDBL nonut self-threading screw from SFS, the manufacturer of high performance fasteners, is said to enable a secure connection of pre-drilled supporting steel structures without any nuts or washers. Compared to the standard method of using nuts, bolts and washers, SFS says the precision-engineered TDBL nonut fastener is a quicker, more efficient and secure way of fixing supporting steel structures of various thickness and hardness together, subject to static load. According to SFS, the installer only needs one component instead of three and one hand tool. Installation is one-handed and requires access from just one side. Thanks to the design of the TDBL nonut with its thread-free zone and additional serration under the head, SFS says the risk of over-driving in thin steel is prevented and the connection remains robust. Europeanmanufactured to a high quality, the plated carbon steel, case hardened TDBL nonut is available in eight variants according to length, diameter and clamping length with a hexagon head. Well established in Germany, SFS reports that the TDBL nonut is the only product of its kind with the German national technical approval (Allgemeine bauaufsichtliche Zulassung). It is also widely used across mainland Europe and the rest of the world in applications such as steel beams, stairways, railings, pylons, water tanks, grain silos, fall protection systems, rack constructions and solar parks. A current case study is Panama airport, where 28,000 TDBL nonuts are being used in the project’s construction.

The TDBL nonut has been mainly used in the columns and beam-to-column connections. According to SFS, the product’s unique design has enabled other design changes to be made to the structure of the mezzanine, complementing structural performance and delivering installation benefits. Andy Stolworthy, director of product and market development at SFS UK, said: “The traditional method of fixing steel structures together by using bolts with nuts and washers represents an unnecessarily awkward and timeconsuming way of doing things. We’ve worked to overcome this by developing the TDBL nonut, a technically superior fastener in one piece rather than three. It’s a risk-free alternative that is guaranteed to make steel structure assembly faster, and the customers get the peace of mind of knowing that it’s a product from a global-market leader renowned for quality.” According to SFS, the TDBL nonut is backed with the expert technical support at the core of the company’s success in serving the construction and manufacturing industries. www.sfsintec.co.uk
