Description
Overview
DIN85 defines the dimensional requirements for slotted pan head machine screws, ensuring consistent selection and installation in mechanical assemblies.
This selected size is specified with diameter M6, length 40 mm, thread M6, pitch 1 mm.
Sold in multiples of '100 pieces. 1 Box = '100 pieces.
Material, Grade & Strength
A4 (316) stainless steel provides strong corrosion resistance for marine, coastal and chemical environments.
Finish & Corrosion Protection
Match the finish to the operating environment and corrosion exposure.
Typical Uses
Commonly used in electrical equipment, panels, covers, light machinery, fixtures and general workshop assemblies.
Technical Tips
- Use the correct screwdriver or drive bit to prevent head damage.
- Match the thread size with the tapped hole or mating nut.
- Use washers where load spreading or surface protection is required.
Selection Advice
Confirm the standard, size, material, finish and drive style before ordering to ensure compatibility with the assembly.
