Marsh Brothers M1020-5 SPINNER WASHERS, Polymer, Pack of 5,

The **Marsh Brothers Aviation Yellow Polymer Spinner Washers** (P/N **M1020-5**) provide a durable alternative to conventional thin nylon propeller spinner washers. Traditional nylon washers may require replacement whenever the spinner is removed because pressure from the screw head against the spinner’s curved surface can cause them to fail. The M1020-5 washers are machined from a billet of tough **Thordon polymer**. This material allows the washers to conform to the spinner’s curved surface while resisting cracking and extrusion. They are designed to provide a long service life without frequent replacement. Each package contains **5 yellow polymer spinner washers**. --- ## Applications The **M1020-5** polymer washers are designed for aircraft propeller spinner installations using a **No. 10 round-head stainless-steel screw**. Their diameter and thickness are designed to suit the round-head stainless-steel screws commonly used on propeller spinners. --- ## Why CJ Aerospace?
