0XBIT Rubberized Neodymium Magnet, 4 Pieces Rubber Coated Magnets, Diameter 22 mm, Magnet Discs with M4 External Thread, Suitable for Connecting Tools, Hanging

External rubber protection: the outside of the magnet rubberised is coated with high-quality TPE rubber, which can effectively prevent scratches and damage, and the non-slip coating ensures strong adsorption even on smooth surfaces. Strong magnetic adsorption: the magnetic screws use the strong magnetic material ndfeb, which has a strong magnetic force and a vertical suction power of up to 3.5 kg and thus offers more comfort for your life. Strong and durable: magnets with thread have a permanent magnetic suction power and a strong adsorption force, the screws are coated with high-quality carbon steel, which does not rust easily and has a long service life. Easy to install: Our rubberised magnetic centres come with standard M4 external thread bolts, simply align the threads of the suction cup with the holes of the target tool and tighten it. Wide range of applications: the rubber magnetic disc can be used on a variety of iron surfaces such as cars and doors and is ideal for attaching devices such as ceiling lights for cars, transparent mirrors and doorbells.
