Overview

DIN 963 defines a slotted countersunk machine screw with a flat head designed to sit flush in a countersunk hole. The standard controls the head angle, slot form, thread and dimensional proportions so the screw can be used consistently in light mechanical and panel assemblies.

This selected size is specified with diameter M10, length 35 mm, thread M10, pitch 1.5 mm.

Sold in multiples of '25 pieces. 1 Box = '25 pieces.

Material, Grade & Strength

A2 stainless steel, commonly associated with 304 stainless, provides good general corrosion resistance for outdoor, clean industrial and food-related environments. Stainless threads can gall, so suitable anti-seize may be required.

Finish & Corrosion Protection

Corrosion resistance is provided by the stainless material itself rather than a plated coating.

Typical Uses

DIN 963 countersunk slotted machine screws are used in panels, covers, electrical assemblies, light engineering, fixtures and applications where a flush surface is required with a simple flat screwdriver drive.

Technical Tips

• Use a correctly formed countersink so the head seats evenly and does not stand proud.
• Avoid over-tightening slotted screws as the drive can cam out or damage the slot.
• Use with a tapped hole or matching nut of the same thread size.
• Choose stainless steel where corrosion resistance is required.

Frequently Asked Questions

When should a countersunk screw be used? Use countersunk screws where the head must sit flush with the surface or where a protruding head would interfere with movement or appearance.
