DIN 967 Pan Head Screws with Collar
DIN 967 Pan Head Screws with Collar are designed for assemblies where the screw head needs additional support around the fastening point. The integrated collar beneath the pan head creates a wider bearing area against the assembled component, helping distribute the load around the hole while keeping the screw head above the surface. The cross recessed drive provides straightforward access with a suitable screwdriver or bit, while the raised pan head gives the fastener a visible and accessible fastening point. This combination makes DIN 967 useful for components made from sheet metal, plastic, thin sections, and other materials where the area around the fastening hole needs additional bearing support.
The collar also provides an important selection consideration: the available space around the mounting hole must accommodate the collar diameter. When the assembly requires a flush surface, a countersunk screw may be more appropriate; when additional bearing support is useful and a raised head is acceptable, DIN 967 offers a practical alternative.

Application of DIN 967 Pan Head Screws with Collar:
Panels, Housings and Sheet-Metal Parts
The integrated collar beneath the pan head provides a wider bearing area than a conventional pan head screw, making DIN 967 suitable for securing equipment panels, electrical enclosures, sheet-metal covers, brackets, control boxes, and machine guards. The collar helps distribute the clamping load around the fastening point and can reduce the need for a separate washer in suitable assemblies.
Small and Medium Mechanical Equipment
With sizes from M3 to M8, DIN 967 covers common fastening requirements for compact and light mechanical equipment. Typical applications include instrument housings, appliance components, small machinery, ventilation equipment, pumps, control equipment, and general mechanical assemblies where a relatively compact fastener with an integrated bearing surface is preferred.
Production and Repeated Assembly
The Phillips drive provides a familiar interface for hand tools and powered screwdrivers, making DIN 967 suitable for applications involving repeated fastening during production. It can be used for OEM assembly, electrical equipment production, appliance manufacturing, machine covers, and equipment maintenance, particularly where keeping the screw and bearing surface as one component simplifies handling.
