DIN 966 Raised Countersunk Screws
DIN 966 Raised Countersunk Head Screws combine a partially countersunk head with a Phillips drive, making them a practical choice when the assembly requires a relatively low-profile head together with convenient cross-recess installation. The raised countersunk profile allows the screw to sit partly within a prepared countersunk hole while retaining a visible rounded section above the surface, offering a different seating appearance from a fully countersunk screw.
For customers assembling compact equipment, housings, panels, brackets, and light mechanical components, the Phillips recess provides a familiar driving interface and is particularly convenient for repeated installation with powered screwdrivers. The raised head also gives the fastener a defined seating surface without requiring the completely flush installation associated with a flat countersunk head.
Specification:
DIN 966 screws can be specified according to size, thread pitch, length, material, mechanical grade, surface treatment, and corrosion-resistance requirements. The available size range is M1.6 to M10, covering small precision assemblies as well as light mechanical equipment. Screw length can be selected according to the thickness of the connected components and the required thread engagement.
Material and surface treatment can be selected according to the working environment. Carbon steel is suitable for general mechanical assemblies and can be supplied with finishes such as zinc plating for improved corrosion protection. Stainless steel versions are available with passivation to improve the natural corrosion resistance of the surface after manufacturing. Other finishes can also be considered according to the required appearance, corrosion resistance, and application conditions.

Application of DIN 966 Raised Countersunk Screws:
Compact Equipment and Precision Assemblies
The M1.6–M10 size range makes DIN 966 suitable for compact equipment where standard-size fasteners may be too large or where installation space is limited. Common applications include measuring instruments, control equipment, optical devices, small mechanisms, laboratory equipment, electronic housings, and precision mechanical assemblies. Smaller sizes are particularly useful for securing covers, brackets, panels, and other lightweight components.
Housings, Panels and Sheet-Metal Components
The raised countersunk head provides a relatively low-profile seating arrangement while retaining a defined head surface above the component. This makes DIN 966 suitable for equipment housings, electrical enclosures, control panels, sheet-metal covers, appliance components, brackets, and machine guards. It is a practical choice when a completely flush countersunk head is not necessary but a lower-profile fastening solution is preferred.
Repeated Assembly with Powered Tools
The Phillips drive makes DIN 966 suitable for assembly operations involving repeated fastening and removal, particularly where powered screwdrivers are used. Applications include production-line equipment, electronic product assembly, light machinery, instrument manufacturing, and general OEM assembly. The cross recess provides a familiar driving interface for automated or semi-automated fastening processes.
