Our PA66 nylon hex head screws combine low weight, mechanical toughness, and electrical insulation for versatile industrial fastening. Manufactured from polyamide 66, also known as nylon 6/6, these nonmetallic screws offer a rust-free option for securing equipment housings, electrical components, and lightweight assemblies.
The external hex head allows installation with a standard metric wrench or socket, while the fully threaded shaft engages with compatible nuts or tapped holes. Following the ISO 4017 dimensional format, these metric nylon screws provide familiar fastening geometry for assembly and maintenance.
PA66 offers good rigidity and abrasion resistance. Its properties vary with moisture exposure, so operating humidity, temperature, and load should be considered when selecting the screw for your application.
