Bekaert Vis à tête M4x8, acier inoxydable

This is a Bekaert head screw, M4x8, made from stainless steel. The catalogue lists it under miscellaneous parts and fittings. Parts of this type are general-purpose fasteners used to secure components within burner and boiler assemblies. Typical applications include attaching covers, mounting brackets, electrode holders, or fixing control box covers and valve flanges. The M4 thread and 8 mm length are standard metric dimensions. The stainless steel material offers sufficient corrosion resistance for the environments encountered in boiler rooms and around combustion equipment. When replacing such a screw, match the thread size and pitch precisely: metric coarse is standard for M4. Also confirm the head type—pan, hex, or countersunk—to fit the original recess or tool clearance. Using a stainless steel screw of the correct length and thread is essential to avoid stripping or loosening over time due to thermal cycling.
