The SX3 functional safety linchpin, here explicitly the SX3 starter set large with triple safety, is used as a safety element (pin safety device) in mechanical engineering and vehicle construction.

This linchpin combines three decisive and permanently consistent safety functions in its bolt head.


Thanks to the patented bolt head/spring washer design, the spring washer is held in the groove of the bolt head in the open and closed position. In the open position, unintentional folding backwards or forwards is impossible. In the closed position, only opening by the user is possible.


This results in three major advantages for every user:


--> no automatic opening

--> no automatic closing

--> no loss of the folding pin

SX3 starter set large incl. SX3 KFS from 4x27mm to 11.5x52mm

SKU: 04115
  • To be able to test the SX3 properly, we have put together a starter set for you. Two of each size, so that you can expect optimum test results.
