A Specialist Manufacturer of Plastic Nuts
Bluemay manufactures and holds stock of an extensive range of thermoplastic nuts in a broad selection of thread sizes and formats. In addition to our standard range, we can respond quickly to customer requirements for specific designs, dimensions or application needs
Thermoplastic nuts offer an excellent balance of strength and weight, making them a practical alternative to metal fasteners in many industrial and specialist environments. They provide reliable load-bearing capability while remaining lightweight, corrosion resistant and inherently vibration resistant. Their non-conductive properties also make them well suited to applications where electrical insulation is important.
To support branding, identification or aesthetic requirements, custom colors are available on request, allowing your fasteners to align with project specifications or corporate design standards.
Bluemay thermoplastic nuts are available in a range of stock sizes for immediate dispatch — with custom options on request.
Our standard materials include nylon 6.6, nylon 6 and polypropylene, offering different performance characteristics to match strength, impact resistance and environmental demands. Many sizes and formats are available from stock for immediate dispatch, with additional color options available to meet identification or design needs.
