Connector Square SEMS Screw is designed for applications that require strong, stable, and precise fastening, especially in connector and electrical assemblies. It features a square-shaped connector head combined with a pre-attached (captive) washer, supplied as a single ready-to-use unit for improved efficiency.

The square head design provides better grip and prevents rotation during installation, ensuring easy alignment and secure locking in position. The integrated washer enhances performance by distributing load evenly, protecting the surface, and reducing the chances of loosening due to vibration.

By eliminating the need for separate washer handling, this SEMS screw significantly reduces assembly time and increases productivity, making it suitable for both manual and automated processes.

Manufactured from high-quality materials such as Mild Steel, Stainless Steel (SS 202 / SS 304), and high tensile grades, Connector Square SEMS Screws offer excellent durability, strength, and corrosion resistance in various environments.

These screws are widely used in electrical connectors, panel boards, industrial equipment, machinery assemblies, and other applications where secure and vibration-resistant fastening is essential.
