Product Description

RS PRO 158-3590 Pozidriv Countersunk Stainless Steel Machine Screw M3 20 mm is a precision fastener designed to provide a flush finish and superior durability. This machine screw features a countersunk flat head, which allows it to sit flush or below the surface in pre-drilled, countersunk holes. The Pozidriv drive offers enhanced engagement and reduces ejection force when tightening or loosening screws.

Constructed from high-quality A4 316 marine grade stainless steel, it delivers outstanding resistance to corrosion, particularly chloride corrosion, making it perfectly suited for use in harsh environments such as marine settings, chemical plants, dairy processing, and medical sterilising equipment. The grade 316 stainless steel also withstands extreme temperature variations, ensuring longevity and structural integrity.

The machine screw has an M3 metric thread that ensures compatibility with pre-tapped holes, creating strong, reliable joints without the tapered shank found on wood screws. These screws are typically used to securely hold components in industrial machinery, vehicle engines, and marine equipment.

This product meets DIN 965 standards, guaranteeing the quality and mechanical properties expected from industrial-grade fasteners. Its design and material selection make it easily cleanable and suitable for demanding applications requiring resistance to chemical and environmental exposure.

Flat countersunk head creates a flush surface for aesthetic and functional applications. Pozidriv drive type improves screwdriver grip and reduces cam-out risks. Marine grade A4 316 stainless steel ensures excellent corrosion resistance.

Complies with DIN 965 standards for machine screws. Ideal for industrial machinery, boat fittings, chemical plants, and medical equipment. Thread size M3 with 20 mm length for versatile use. Suitable for high-corrosion environments due to chloride resistance.

Robust and provides clean, strong fastening solutions in demanding applications.
