These RS PRO hex socket button screws are a type of fastener you can use for light-duty assembly works. They feature a low-profile, rounded dome-shaped head with a hexagon drive. These screws have wider heads and lower profiles, which makes them ideal when you need a broader bearing surface.
They are made of 10.9-grade steel for strength and durability. These fasteners are suitable for use in applications that don't require corrosion-resistant fasteners but you can still use them outdoors if they are painted or treated. You need a hex key or Allen key to install them.
You would generally see hex socket button screws like these used in machine tools, engineering and domestic applications. This product is threaded in accordance with the ISO 7380 standard specifying hexagon socket button head screws so you can be sure that it is grade-A quality. It also meets ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007 Electrostatic Control Standards and has been subjected to rigorous electrostatic discharge (EDS) control testing, which means the risk of electrostatic discharge (ESD) is minimised.
