RS PRO Brass Plain Washer, 0.8 mm Thickness, M4


Use this RS PRO flat washer to evenly distribute tensile stress across flat surfaces. It'll help you screw in nuts and bolts securely while protecting the surface you're fixing to from damage or indentation. It ensures a secure connection that won't loosen and it prevents objects from wobbling or rattling.
The washer's brass body means it easily conducts electricity and heat, making it suitable for use in electrical and thermostatic instruments. You can use the item in high-moisture environments as it's resistant to corrosion and rust.
The thinness of the washer allows you to stack it with others to form a spacer for long bolts and screws so that these don't poke through the bottom of objects or surfaces. This product complies with the Restriction of Hazardous Substances (RoHS) which means it contains minimal amounts of any harmful metals like lead or mercury.
