M20 x 40mm Hex Set Screw | DIN 933 | A4-80 Stainless Steel
For control panel fabrication, this M20 x 40mm Hex Set Screw provides a practical hex head fixing with thread coverage across the full length.
The A4-80 stainless steel specification offers strong corrosion resistance with a higher tensile grade for exposed equipment, marine projects and demanding external assemblies. The M20 thread size makes it easy to match against compatible nuts, washers and tapped components without changing the installation method.

- 2.5mm pitch provides predictable thread compatibility across standard metric components
- 12.9mm head height helps with clearance planning during equipment design
