RS PRO M3 x 12 mm Zinc Plated Steel Pan Head SEM Screw, External Tooth Washer


Looking for a screw that comes with a washer already installed on it? Try these SEM ones (short for preassembled) from RS PRO. They're made of zinc-plated steel, so they're strong and have good resistance to corrosion. This means you can install them both indoors and outdoors.

These screws are supplied in bags of 100, so you'll have more than enough for a small repair project. If you have to install a long line of these bolts, the pre-attached washers will save you loads of time. Screws like these are used on a wide range of projects, from installing panels on roofs to joining together wood. They meet Restriction of Hazardous Substances (RoHS) standards, which means they contain only minimal amounts of any harmful materials.
