Our GRP screws are ideal for applications where electrical insulation is crucial or where only GRP products may be used. We would be happy to assist you in selecting the right screws for your application.
GRP threaded rods offer high electrical insulation, corrosion resistance and low weight. They are used when metal-free fastening solutions or exclusively GRP materials are required. Contact us for the right design.
GRP nuts offer high electrical insulation, corrosion resistance and low weight. They are used when metal-free connections or exclusively GRP components are required. Contact us for the right design.
The standard length of the GRP threaded rods is, depending on the thread size, either 1200 mm or 2000 mm. We also offer matching GRP nuts.
