RS PRO Brass Plain Washers, M12, DIN 125A

The washer is suitable for use in thermostatic or electrical instruments, as its body is made of a brass material that easily conducts heat and electricity. The material is also highly resistant to rust and corrosion, so you can use this washer in high-moisture environments. The thinness of the washer allows you to stack it with others to form a spacer for long bolts and screws so they don't poke through the bottom of objects or surfaces. As this product complies with the Restriction of Hazardous Substances (RoHS) directives, it contains only minimal amounts of any harmful materials.
