Slotted CSK Head Machine Screw:M4 x 20 - DIN 963/4.8/ZP

This slotted countersunk head machine screw is manufactured from steel to DIN 963 standards, featuring a zinc plated surface finish for corrosion resistance. Rated at property class 4.8, it provides reliable mechanical fastening suitable for general engineering applications. Buyers typically select this screw when a flush seating profile is required, allowing the head to sit level with the substrate surface. The M4 nominal diameter and 20mm length define its primary sizing dimensions for specific assembly needs. Selecting this grade ensures a balance of strength and cost-effectiveness for non-critical structural joins.
