Description
The 304 SS Pan Head Self Tapping Screw is a precision-engineered fastener that combines strength, corrosion resistance, and versatility. Manufactured in compliance with JISB1122 standards, this pan head self-tapping screw is designed to create its own threads in pre-drilled or punched holes, offering reliable fastening across a variety of materials such as sheet metal, plastic, and wood. Made from premium AISI 304 stainless steel, this screw delivers excellent resistance to rust, oxidation, and environmental wear, ensuring long-term durability even in humid or outdoor conditions. The large pan head provides a wider bearing surface for secure fastening, while the cross groove (Phillips) design enables easy installation and consistent torque application.
Features & Benefits
- Large Pan Head Design: Offers a broad contact surface for better load distribution and secure fastening without damaging softer materials.
