Nylon Countersunk Cross Recessed Screws
Description
Nylon countersunk cross recessed screws are designed for applications where a flush finish is required and metal fasteners may cause corrosion, electrical conduction, or scratching. These screws are moulded from high-quality nylon and provide excellent electrical insulation, low weight, and good chemical resistance. They are suitable for use in electronics, clean environments, and light mechanical assemblies where a neat countersunk head and non-metallic construction are preferred.
Features
- Countersunk head with cross recessed drive for easy installation and a flush surface finish
- Non-metallic, non-magnetic and electrically insulating
- Lightweight and corrosion-resistant, suitable for humid and chemically aggressive environments
- Smooth surface to reduce the risk of scratching or marking delicate components
- Available in metric sizes M2–M6 and a wide range of standard lengths
- Supplied in white or black to support visual coding or aesthetic requirements

Applications
These nylon countersunk screws are suitable for applications where a flush finish, electrical insulation, and non-corrosive performance are important. Typical uses include fixing covers and panels in electronic assemblies, mounting components on PCBs or insulating plates, and general-purpose fastening in clean or light-duty mechanical environments where metal fasteners are undesirable.
