Description
Overview
DIN84 defines the dimensional requirements for slotted cheese head machine screws, ensuring consistent selection and installation in mechanical assemblies.
This selected size is specified with diameter M4, length 8 mm, thread M4, pitch 0.7 mm.
Sold in multiples of '200 pieces. 1 Box = '200 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.
