Our Uniscrew caps protect the screw heads from shocks and dirt and at the same time gives the heads a nice finish. It accepts a wide variety of screw sizes, which reduces stocks as well as assembly times thanks to its integrated washer. The manufacturing material is a copolymer PP (polypropylene) with a very high resistance to impacts resistant even at temperatures of -20ºC . It contains also a UVA additive to prevent degradation as a result of sunlight and bad weather.

During the manufacturing of these pieces we use an additive that favors their biodegradation without affecting their behavior during their useful life. Check here for more details about the properties of the biodegradable additive.
