About this product
The Self Tapping Screw 4.2x38mm is a high-quality metal fastener designed to deliver superior holding power and long-term reliability. Manufactured from hardened steel and finished with a zinc coating, this screw resists rust and wear, making it ideal for both indoor and outdoor use.
With its sharp, self-tapping point, this screw can cut its own threads as it is driven into materials — eliminating the need for pre-drilling. This saves time and reduces labor costs, especially in construction, carpentry, roofing, and general repair projects.
Whether you are a professional installer or a DIY enthusiast, the 4.2x38mm screw offers unbeatable strength and consistent performance, ensuring your assemblies stay secure and neat.
Applications
• Metalwork: Fasten sheet metal, ducts, and light-gauge steel structures.
• Woodworking: Ideal for joining wood boards and panels securely.
• Plastic Installations: Works well for PVC, polycarbonate, and other plastics.
• Electrical & Plumbing Fittings: Mount brackets, conduits, and fixtures efficiently.
• General Construction: Reliable for wall framing, roofing, and furniture assembly.
Key Benefits
• Strong Grip: Hardened steel design ensures a solid, long-lasting hold.
• Corrosion Resistance: Zinc coating prevents rust in humid or outdoor environments.
• Time-Saving: No need for pre-drilling — screw taps directly into the material.
• Multi-Material Use: Compatible with metal, wood, and plastic.
• Precision Threading: Ensures smooth penetration and reduces cracking or splitting.
