Detailed Engineering Specifications

Purpose-built for heavy-duty applications, this M12 x 54mm hex head cap screw features a robust polycarbonate composition. With a nominal thread diameter of M12 and a length of 54mm, it provides significant clamping force. The head width measures 12mm, accommodating standard tooling. Polycarbonate offers superior corrosion resistance, making it ideal for use in chemically aggressive or humid environments. Its high impact strength and non-conductive properties also lend themselves to applications in electrical assemblies and areas where sparking is a concern. This fastener is designed for applications requiring strength without the weight or conductive properties of metal.
