RS PRO Pozidriv Countersunk Steel Machine Screw M6, 20 mm, DIN 965, Passivated Zinc Plated 553-526

RS PRO presents the high-quality Pozidriv Countersunk Steel Machine Screw, model 553-526. Designed for precise and robust fastening in demanding environments, this machine screw features an M6 metric thread and measures 20 mm in length, making it suitable for assembling a wide variety of pre-tapped components. Its flat, countersunk head allows the screw to sit flush with or below the material surface, ensuring both a clean finish and compatibility with applications requiring covered or unobstructed surfaces.

The Pozidriv drive type offers improved engagement and reduced cam-out, thanks to its cross recess design with eight points of contact. This ensures secure tightening and minimizes ejection forces for both installation and removal. Manufactured from steel and treated with a passivated bright zinc plating (BZP), the screw resists corrosion and rust, providing extended service life even in challenging conditions. Although BZP steel offers excellent value compared to stainless steel, it still delivers robust durability for industrial tasks.

Conforming to DIN 965 standards, this machine screw guarantees uniform quality and compatibility across a range of mechanical assemblies. Its straight shank and full thread allow for strong joints in pre-tapped holes, suited for both machine and manual assembly. Machine screws like this are commonly used for securing electrical panels, PCB prototyping, circuit board mounting, and general production engineering. The flush finish allows other components or covers to be placed over the screw head without obstruction.

Whether employed in electrical, industrial, laboratory, or manufacturing settings, the RS PRO Pozidriv Countersunk Steel Machine Screw brings versatility and reliability to projects that require precision fastening. Its corrosion-resistant finish and compliance with industry standards make it a preferred choice for maintenance, repair, and assembly.
