The 3RACING Aluminium M4 Countersink Washer pack in titanium is intended to give secure, low-profile fastening for RC components. They are a compact solution for builders wanting neat joins without excess mass.
These washers ensure screws sit flush with countersunk holes, cutting down on sharp edges and improving body and chassis fit. The titanium option offers a good balance of toughness and low weight, handy when adjusting setups or swapping parts trackside.
Although optimised for M4 hardware, these washers can be used in a variety of model assemblies where a countersunk seat is required. Their adaptability makes them a useful addition to any parts box.
