Material and Finish
Gaskets can be produced in different materials and with different surface treatments; all in accordance with RoHs/ELVV regulations.,

material
Carbon steel hardness 465-550HV10 hardened and annealed
·Stainless steel AISI 316L EN10088-14404, surface hardness ≥550HV0.05 after surface hardening
·Other materials can be customized according to customer requirements (hydrochloride-resistant nickel-based alloy C-276, etc...)

surface treatment
KL100+VH301 Cr6-free red corrosion resistance is at least 600 hours (salt spray corrosion test according to ISO9227)
Mechanical galvanized + seat seal without Cr6 red corrosion resistance at least 600 hours (salt
Fog corrosion test according to I5O9227)
·Other surface treatment according to the minimum order quantity

safety fastening system
To ensure a complete fastener thread system, the company's secure fastening system utilizes tension rather than friction based on traditional fastening methods, this method ensures the secure fastening of the threaded system.
The secure fastening system is a pair of two identical flat washers with cam teeth on one side and radial knurled teeth on the other.

performance
The inclination angle a of the unique cushion circle cam teeth must be greater than the angle B of the bolt thread.
The coefficient of friction of the outer knurled tooth surface of the washer is much higher than that of the cam tooth surface.
Washers are much harder than bolt/nuts of all grades (8.810.9 and 12.9).

advantage
This fastening solution ensures optimum locking performance against shocks and dynamic loads.
The system can be used independently under lubricating oil conditions. This system can ensure safe fastening under non-lubricated conditions and can also work under lubricated conditions. However, it is still recommended to use high-quality lubricants, which can make safe fastening System performance is maximized
. This fastening system can be reused without loss of performance. In the case of repeated use, to properly position the gasket, it is necessary to check that the cam teeth face the cam teeth.
Fastening elements can be locked with high or low preload forces.
· Can be reused for any kind of bolts/nuts of any grade (up to grade 12.9).
· Does not need to be re-tightened.
·The surface treatment does not contain Cr6, so there will not be any danger of hydrogen embrittlement.
·The gasket pieces are glued into pairs, and the cam teeth face the cam teeth surface, in order to facilitate the installation of the convenient system.
