The M4 Tube for metric thread screw is a mounting piece that is made of brass with a smooth finish in natural brass, which makes it also light-resistant. They are obtained in packages of 2,000 units of M4 tubes. Its internal thread design is designed to offer a fair and exact grip on furniture, shelves, cabinets, among others, to the M4 screws with metric thread and the M4 screws with extra-flat head, the objective is to facilitate the holding of these grip pieces in materials in which its installation is difficult. These types of tubes are embedded in the board, then the screws are threaded.

Fixing accessory made of natural brass, designed to accommodate M4 screws in wooden structures and other materials.

This tube acts as a reinforcement sleeve for M4 screw connections, ensuring a secure fixing in materials such as wood, melamine or composite boards. It is embedded in the board and allows for a firmer connection by correctly accommodating the screw.

It is made of brass with a natural finish, which gives it excellent corrosion resistance and long life even in environments with variations in humidity or temperature, such as kitchens and bathrooms.

The tube must be inserted into a pre-machined hole in the panel. The M4 screw is then inserted to complete the fixing. The process improves the accuracy of the assembly and reduces wear on the base material.

This tube is ideal for M4 screws with extra flat head, which facilitates flush and secure fastening, minimising interference with other furniture parts or fittings.

It provides greater mechanical strength in loaded joints, improves assembly repeatability in production runs and optimises the performance of metric bolts, preventing loosening due to wear or vibration.
