Pass it on and recommend!

Whether manufacturer, wholesaler or retailer, everyone wants to earn something from a product!

Why not you too?


  1. buy product

  2. apply product

  3. Recommend product

  4. Earn on the product

Benefit from your "word of mouth or your recommendations".

The best salesperson is neither employed by us nor is he a free agent or one of our sales staff. The best seller is a satisfied customer who acts as an active, positive recommender for us, our product and our service.


In our opinion, recommendation marketing or word of mouth is the most effective marketing tool, which is mainly due to the following points:

  • As a recommender, you have a trust bonus because you are primarily convinced of a product and are not acting out of an exclusively monetary intention.


  • Your recommendations appear neutral, more credible and loyal.

  • The recipient of the recommendation can literally feel your enthusiasm.


Every day we consumers are confronted with a huge range of goods. If we feel overwhelmed and can't decide - let's ask someone we know.

  • A kind of "advance sale" takes place through the recommender, i.e. you.


  • The result is much greater efficiency because the conversations are shorter, have less resistance and get to the point faster.

  • The probability of closing increases enormously and the recommendation marketing is therefore highly effective - this results in your financial reward.

With our referral marketing, we give you the money that wholesale/retail would normally get!


We prefer to invest in a satisfied customer - if you want, also in you!


Are you enthusiastic about our product?!


Order your SX3 conveniently and easily via our online shop.


You are absolutely convinced of the SX3?!

Recommend us and share your experiences with friends, acquaintances or even strangers.

The beauty of it is that you make it a product out of sheer conviction!

If the referrer also orders one of our products and gives you as a reference, we will reward you with a bonus.


Would you like to achieve even more and earn money with our products?

  • You can also benefit in the future and sell our product to new or existing customers.​

SX3 Functional linch pin


The SIMTECX SX3 functional linch pin with 3-fold safety is used as a securing element (pin securing) in machine and vehicle construction.

This linch pin combines three crucial and safety functions that remain the same over the long term in its bolt head.

Thanks to the patented bolt head/spring washer construction, the spring washer is held in the groove of the bolt head in both the open and closed state. In the open position, unintentional folding backwards or forwards is impossible. When closed, it can only be opened by the user.

This results in three essential advantages for every user

--> no automatic opening

--> no automatic closing

--> no losing the linch pin

SX3 Functional linch pin


The SX3, a product - 100% MADE IN GERMANY.

The complete development and production of the 

bolt/spring ring is carried out in Germany.


The precision bolt offers the highest security against the automatic opening of the spring ring. Due to the choice of steel, the specially developed bolt head as well as the bolt shaft gets its necessary hardness on the outside and its required toughness in the steel core.


The spring ring is made of a specially manufactured spring steel wire. The uniquely developed shape of the spring ring locks into the groove in the bolt head and provides maximum security against unintentional opening and closing.


Endurance tests have shown that the split pin provides consistent security even after several thousand closing and opening operations. The spring washer shows no signs of fatigue and is still held in the groove just as it was at the beginning.


The pin head was deliberately designed without a third hole to accept a safety chain or safety cord. This makes it possible to reduce the bolt head dimensions. Because the spring washer is held firmly in the groove, a safety chain can be attached directly to the spring washer as required, thus eliminating the need for a third hole.

Care and Maintenance

The SX3 can be used under the most extreme conditions!


In order to be able to guarantee long-term optimal and consistent quality, you should occasionally add some oil or penetrating oil to the two bores. Complete!

Der SIMTECX SX3 KFS KAT 2 und 2-3 Funktions-Klappsplint mit 3-facher Sicherheit dient als Sicherungselement (Bolzensicherung) im Maschinen- und Fahrzeugbau. 

Dieser Klappsplint vereint drei entscheidende und dauerhaft gleichbleibende Sicherheits-Funktionen in seinem Bolzenkopf.

Durch die patentierte Bolzenkopf-/Federring-Konstruktion wird der Federring im geöffneten wie im geschlossenen Zustand in der Nut des Bolzenkopfes gehalten. In der Offenstellung ist ein ungewolltes nach hinten oder nach vorne Klappen ausgeschlossen. Im geschlossenen Zustand ist nur ein vom Anwender gewolltes Öffnen möglich.

Daraus ergeben sich drei wesentliche Vorteile für jeden Anwender

--> kein selbsttätiges Öffnen

--> kein selbsttätiges Schließen

--> kein Verlieren des Klappsplints
