Knurled thumb screws in polyamide and other materials

17 September 2009

Five new models of knurled thumb screws with conical extension complement the range of BÜLTE plastic screws. The standard material is polyamide, which is resistant to various chemical products, has excellent mechanical properties including wear resistance, low friction coefficient, high melting point and good impact resistance.
Other materials are available on request, such as PP, PE and POM (these materials are recommended for their good food and medical qualities) or PA glass filled (tensile strength and high rigidity - it ideally replaces aluminium and zinc in tap parts).
The knurled thumb screws are available in M5, M6 and M8 (Length from 6 to 60mm).
The standard colour is natural but they can also be supplied in a wide range of colours to suit requirements.
