The Yokomo ZC-SS43LA M4x3mm thread lock set screw is a practical accessory for keeping parts locked in place on RC models. Its small profile and thread locking property make it handy for ensuring assemblies stay tight during runs.
With a 4 mm diameter and 3 mm length, this set screw is made to resist loosening under vibration. It is commonly used to secure the centre drive shaft on models such as the YZ-4SF, helping maintain consistent operation.
Each pack contains five screws, giving you replacements for routine service or small upgrades. Their size and thread lock feature make them suitable for a range of compact RC fittings.
