Understanding the technical details of this nut is crucial for selecting the right fastener for your project. Below are the key specifications:
- Thread Size: M5 (5mm)
- Thread Pitch: 0.8mm
- Width Across Flats (A/F): 8mm
- Nut Thickness (H): 4mm
- Material: Stainless Steel (A2/304 or A4/316)
- Standard: DIN 934-ST
- Finish: Natural Stainless Steel
The above specifications align with ISO 4032 and EN 24032, making this nut interchangeable with similar metric hex nuts across various industries.
Material and Corrosion Resistance
The Nut M5 x 0.8mm Metric Hex DIN 934-ST SS is made from stainless steel, typically of A2 (304) or A4 (316) grade.
Stainless Steel A2 (304)
