One of the most common problems that occur when tightening fasteners is ‘galling’. While galled fasteners will certainly not be loose, the related joint won’t be properly tensioned and can fail from fatigue when put under service loads. As a result, the equipment may be affected, with mating components being seized, stripped, twisted off or sheared. Here, Chris Herling, applications engineer at...

Today the world of lightweight construction can no longer be imagined without plastics, as they conquer more and more sectors. Their great flexibility in terms of processing and component design leads to an increasing replacement of metallic materials. Due to their outstanding mechanical properties, low weight and attractive manufacturing costs, plastics are a fundamental part of industry today...

The frames of modern railway carriages are constructed almost exclusively from aluminium, which means virtually every threaded hole needs to be reinforced using some kind of threaded insert. Loksert key locking inserts, from Bordo International Pty Ltd, are ideally suited to the high pressure and vibration of rail applications and are used extensively by all the world’s major manufacturers. Lok...

Noise protection walls next to railway tracks must be designed to withstand permanent dynamic loads, with the Nord-Lock wedge-locking principle an established method of securing such systems. That is why KRAIBURG STRAIL GmbH & Co KG has relied on this technology for its newly developed mini sound protection wall. The prototype was tested for the very first time in the German city of Neuss,...

Huck’s pre-assembled, one-piece blind fasteners are ideal when access from only one side of the joint material is available. The blind fastener is placed in a pre-drilled hole and is installed by using an installation tool to pull the mandrel or pin head into the rivet body, expanding the rivet body and causing it to flare on the blind side of the joint material creating a permanent and vibrati...

Now celebrating its 45th anniversary, Rivit has grown with the continuous aim of being a fastening systems benchmark for everything concerning the tools and machines for sheet metal assembly. Rivit Srl started out as a small company operating in the distribution of small metal parts. Step-by-step the business developed its own production of blind rivets, which was expanded later to other famili...

By Mark Thurber, CEO at Maelstrom Chemical Technologies LLC Small component manufacture is as general a subject matter category as one could imagine. Any spring, nut, screw, clip, pin, bolt, anchor, casting, stamping, fitting or assortment of these items – combined into a sub-assembly and destined eventually to be part of a finished article, could fall under this heading. Even more obvious, yet...
