WHY WATERPROOF SCREWS

Thanks to that patented design, our solutionsensure perfect protection and sealing for your systems. This system integrates a O-ring silicone in a groove machined under the head of the screw. It is compressed inside the bore and not between the screw head and the contact surface.

When tightening, direct contact between the screw head and the support is therefore maintained. Without this groove, the O-ring would not ensure a good seal, it would be compressed (or damaged) by the screw head on the contact surface and would be irreparably damaged.

This new system has been designed not to compress the joint by more than 20%, thus guaranteeing better hold and lifetime increased.

This also allows several reuse of the screw/gasket assembly without the risk of forgetting the gasket or reusing a damaged gasket during maintenance operations.

This technology adapts to all screws from M2 and depending on the screw head (Cruciform, CHC, Hexagonal, countersunk, etc.).

PRINCIPLE OF THE MACHINED GROOVE UNDER THE SCREW HEAD

A groove is machined under the head of the screws to accommodate an O-ring which allows the perfect seal of your equipment.

The groove is deep enough to accommodate the seal, without losing metal/metal contact. The dimension of the machining is specially designed to avoid weakening the part.

Countersinking is recommended to accommodate part of the joint, see the drawing below:

WHICH RUBBER TO CHOOSE FOR THE SEAL?

There are several types of seals so that your waterproof screws are compatible with the environment of your application. As standard, silicone is used in manufacturing. Here are the different elastomers offered:

Silicone
Fluoro-silicone
Neoprene
Buna N (Nitrile)
Fluorocarbon (Viton®)
EPDM

Elastomer production is one of the fastest growing areas of manufacturing and there are over 20 different types of elastomers that serve different functions both in manufacturing processes and in the finished products themselves.

The type of elastomer affects the physical properties, functions and lifespan of your parts. Therefore, it is important to test different elastomers when assembling your product to determine which one best suits your needs.

Here we offer you a practical guide to the different types of elastomers used as well as some of their most common applications.
