Import Din965 Csk Machine Screw — Buy in Bulk from Supplier in China

The DIN965 CSK Machine Screw is a countersunk head fastener manufactured to the DIN 965 standard, designed for flush mounting in drilled holes. This listing specifies diameters from M3 to M8 and lengths from 6mm to 200mm, with material options in carbon steel or stainless steel. The thread pitch follows metric ISO standards, and the head angle is 90 degrees as defined by DIN 965. Surface finish is not specified but typically includes plain, zinc-plated, or passivated variants depending on grade.

Carbon steel variants are usually grade 4.8 or 8.8, conforming to ISO 898-1, while stainless steel options are typically A2-70 or A4-80, per ISO 3506. These materials provide corrosion resistance suitable for indoor or mild outdoor environments. The screws are not coated unless specified, and any plating or coating must be confirmed per batch. Typical tolerances for diameter and length follow ISO 2768-1 general tolerances for machined parts, with no tighter tolerances stated.

These screws are commonly used in machinery assembly, electronics housings, automotive brackets, and structural steel connections where a low-profile head is required. Buyers include industrial equipment manufacturers, automotive suppliers, and electronics assemblers sourcing bulk fasteners. Packaging is typically 500 to 2000 pieces per small box, with cartons holding multiple boxes for bulk shipment.
