Self-Tap Screw 4mm(STM4-12)

Self-tapping screws are powder coated in black colour. Size M4 X 18mm

Cuts its own thread while being driven into the mating material. The thread cutting screw makes a small hole while entering the material which creates a tight friction fit between the threads. This helps fight vibration loosening and allows the parts to be taken apart if needed.

12 Screws are in the Kit.
