Description
Overview:
The M6 Spring Ring (DIN 128) is a genuine Makita fastening washer designed to help stop M6 bolts and nuts from loosening under vibration and load. Made from durable, hardened steel, it works by maintaining tension in bolted joints, improving reliability in demanding power tool applications. It is commonly used across Makita machines, including circular saws such as the BHS630 and BSR730, as well as routers, trimmers, breakers, and lawn and garden tools. Fitted beneath a bolt head or nut on an M6 fastener, this compact component supports safe, long-lasting assemblies and helps preserve tool performance. As a genuine Makita part, it offers a precise fit and consistent quality for routine maintenance and repairs.
Key Features:
- Genuine Makita part for assured fit and compatibility

- DIN 128 specification for consistent performance
- Helps prevent loosening from vibration and shock loads
- Simple to fit: place under the nut or bolt head on M6 fixings

Typical Applications:
Used wherever M6 fasteners need extra security on Makita equipment, such as blade guards, base plates, handles, housings, and accessory mounts. Common on circular saws, routers, trimmers, demolition hammers, and cut‐off saws. Ideal for service tasks that restore clamping force and prevent fasteners backing off during frequent use.
Also known as:
Often referred to as a split washer, helical washer, shakeproof washer, anti‐loosening washer, locking ring, or M6 split ring. These terms describe the same type of spring action washer used to maintain preload and reduce fastener movement under vibration.
