RS PRO M5 x 16mm Zinc Plated Steel Pan Head Sems Screw, External Tooth Washer

Need screws that will save you time during installation? These RS PRO SEM (preassembled) screws are supplied with a pre-installed washer. As they're made of zinc-plated steel, they're long-lasting and corrosion-resistant, even when used outdoors or in harsh industrial environments.


The screws come in a bag of 100, giving you an adequate supply for a small repair project. They comply with RoHS (Restriction of Hazardous Substances) requirements, so they contain only trace amounts of any hazardous materials. These types of screws are suitable for applications such as joining wood together and installing roof panels. They're a good choice for installing a long line of bolts as the pre-attached washers reduce user effort.
