DIN7985 Pan Head Screws
DIN 7985 Pan Head Screws feature a raised, rounded head with a cross recess that provides convenient screwdriver access while leaving a compact fastening profile above the workpiece. The head shape offers a practical balance between bearing surface and overall height, making these screws suitable for general machine assembly and components where a conventional hexagonal head is unnecessary.
The screws are available with Type H (Phillips) or Type Z (Pozidriv) cross recesses, allowing the drive style to be matched with the preferred installation tools. Metric thread sizes can be supplied in different lengths, materials, strength classes, and surface finishes according to the application. Their compact head and cross-drive design make DIN 7985 screws suitable for machine components, sheet-metal parts, electrical enclosures, equipment panels, brackets, covers, and general mechanical assemblies where easy installation and a neat finished appearance are required.

Application of DIN7985 Pan Head Screws:
Sheet-Metal and Thin Components
The rounded pan head provides a wider bearing area than a very small low-profile head, making DIN 7985 screws practical for sheet-metal parts, covers, panels, brackets, and light mechanical components. The cross recess also allows straightforward installation with commonly available hand or power tools.
Enclosures, Covers and Access Panels
The compact rounded head works well for electrical enclosures, equipment covers, instrument panels, control boxes, and access plates, where the fastener needs to provide reliable clamping without the bulk of an external hexagonal head.
Repetitive Production Assembly
For products assembled in relatively high quantities, the cross-drive format allows fast installation with standard screwdrivers or power drivers. This makes DIN 7985 suitable for fixtures, small machines, fabricated components, and production assemblies where installation speed and easy tool access are important.
Type H and Type Z Drive Selection
DIN 7985 is available with Type H and Type Z cross recesses. The drive type can therefore be selected according to the tooling already used on the production line. For repetitive assembly, matching the screw recess with the correct driver helps maintain consistent engagement and reduces unnecessary recess damage.
