RS PRO Pozidriv Pan Head Stainless Steel Machine Screw M4 20mm, A2 Grade, DIN 7985, 528-845

RS PRO 528-845 Pozidriv Pan Head Stainless Steel Machine Screw is a high-quality fastening solution designed for industrial, laboratory, and commercial environments requiring reliability, corrosion resistance, and strength. This machine screw measures M4 in diameter and 20 mm in length, making it suitable for joining moderate-thickness components where a robust and clean fastener is essential. The pan head shape ensures a broad, flat bearing surface that maintains the integrity of the joined materials without countersinking.

Constructed from A2 grade stainless steel (304), the screw provides exceptional resistance to rust, chemical exposure, and temperature extremes, giving it a long service life even in demanding and moist environments. The Pozidriv drive design enables a more secure engagement with compatible screwdrivers, minimizing cam-out and supporting reliable, consistent fastening in automated or manual processes.

Compliant with DIN 7985 standards, this machine screw is produced under strict quality assurance protocols, ensuring compatibility with industrial assembly lines, machinery, domestic appliances, food and beverage manufacturing, medical equipment, and non-saltwater marine applications. The plain finish enhances its suitability for environments where cleanliness and easy maintenance are priorities. Its metric M4 threading is uniform along the entire shaft, providing durable and vibration-resistant connections in tapped metal or plastic holes.

Applications for this RS PRO Pozidriv pan head machine screw include fastening electrical panels, assembling process control equipment, constructing clean room devices, and any mechanical or electrical system where routine disassembly and corrosion resistance are needed. Its non-countersinking head is ideal when a flush finish is not required but a reliable, strong join is critical.

This fastening hardware supports efficient manufacturing assembly and rigorous industrial operations, making it an essential component for engineers, maintenance teams, and production technicians. RS PRO’s comprehensive range of machine screws offers quality, versatility, and peace of mind for engineers across sectors.
