This bi-material screw is part of the plastometallic screw range. This cross button is an easy-to-use clamping element. Its star shape allows a good grip.
Made of black nylon and zinc-plated steel, this double material gives it strength.
We can also offer you the same all-plastic screw, the PLAS 70, which is a screw with a conical base.
The 4-arm Bülte screws are suitable for use in the hand due to their star shape without a tightening key.
