With a vast array of different head types and drill-points, you can be sure there is a MASON Screw for every job and application.


The excellence that every MASON Screw exhibit is rooted in the way each and every screw is manufactured. Innovation, coupled with strict quality control and a stringent raw material selection/inspection process makes the MASON Screw a truly world class fastener.

Manufacturing and Material Composition

The MASON Screws are made from the Case Hardened carbon steel, At the factory, wastage is reduced to a minimum and all waste steel from the manufacturing process are recycled. Tool and die are strictly replaced immediately when their specified cycles are up to ensure every screw manufactured is precise, perfect and will be able to perform when it is used, wherever it is in the world.

MASON Screws come with the ceramic coating known as Ruspert coating. This proprietary coating not only protects the screw from corrosion, it also lubricates, to a certain degree, the screw during installation. The Ruspert coating consists of 3 main layers and is extremely tough both physically and chemically.
