Technical Performance

The Fastrax M3 Countersunk Washer represents precision engineering in RC fastener design. M3 represents a metric thread size of 3 millimetres in diameter, making these washers suitable for mid-scale fastening applications across a wide range of RC vehicles from small-scale crawlers to larger competition vehicles. Countersunk washers are engineered to distribute load across a wider surface area whilst sitting flush with countersunk bolt heads, preventing surface damage and maintaining clean lines on your RC chassis, bodywork and internal components. The washer design ensures that when paired with appropriately sized countersunk bolts, the fastening sits completely level with the mounting surface, which is particularly important on visible exterior components where aesthetics matter as much as functionality. The blue colour coating serves both a practical and visual purpose, making inventory management easier whilst adding a professional touch to your builds. These washers are essential for builders working on everything from rock crawlers requiring precision assembly to high-speed buggies where reliable fastening is paramount.
