Material choices for threaded fastener systems

Challenge (Europe) Ltdvisit website


Threaded fastener systems – nuts, bolts, screws and washers used in manufacturing industry at large – are a time-served, well-developed, reliable and surprisingly sophisticated technology. They are also well known, but it is often not appreciated just how critical it may be to choose exactly the right material and finish. This is where Challenge Europe can be of real help.

Manufacturing industry typically requires threaded fasteners in varying grades of steel, stainless steel, copper, brass and aluminium, depending on the installed environment and compatibility with neighbouring substrates.

As explained by Kevin Moorcroft, MD: “The material choice is the most important first step but often just as important is the choice of finish – we offer chemi-black on mild steel, stayblack on stainless steel, zinc plated, chrome plated and nickel plated as standard finishes on many of our fixings.

“We work with design engineers and buyers in all industries to optimise choices and minimise costs so we can ensure highest quality and quickest assembly times for each product.”

Standard products include machine screws, self-tapping and self-drilling screws, as well as machine screw SEMs, thread-forming screws and hammer drive screws.
