Use this RS PRO 4 mm nylon screw insulator to thermally insulate a metal screw, rivet or wire. It's designed to prevent metal-to-metal contact and prevent heat from flowing to other parts of an assembly. It's typically found in commercial and industrial settings like electronics factories and furniture assembly lines.


Thanks to its nylon construction, this durable screw insulator resists corrosion from acids and chemicals, allowing it to last longer. It's easy to install by simply inserting it into a housing to provide a bearing surface for any rotary application.


It accommodates M8 components and has a 14.2 mm flange diameter and a 4 mm body length. Use it in electrical applications, domestic appliances and printed circuit boards, or as a lightly loaded bearing.
