LeanTek offers 2 options for securing joints: the S1 screw and the S4 screw.
Both comprise a screw and a reinforced extended nut, whose job is to ensure that the joint does become unscrewed, whilst remaining easy to use.
S4 differs from S1 in that its threads are pre-treated with a threadlock compound ensuring that the tightened fastening cannot become undone once the micro-capsules have polymerized.
S1 and S4 in use.
Joints from the F-M range are connected to tubes using the S2 cone point set screw.
F-P plates use the S3 screw.
P-I plates use the S5 screw.
The S3 screw in use.
The S5 screw in use (with YB-L and PI-10).
Metal-Base® components are connected together using S6 screws.
