Parafuso de cabeça chata com flange RUKO FLS-DIN373-M-4-fein M4 x 10 mm aço inoxidável A2, 200 unidades

When standard screws fail to distribute clamping force evenly or damage soft surfaces, a flange-head design solves the problem. The RUKO GMBH FLS-DIN373-M-4-fein button head screw with flange combines a low-profile dome head and an integrated flange to provide a larger bearing surface, reducing the risk of pull-through and eliminating the need for separate washers in many applications.

Who is it for

Engineers, maintenance teams, and manufacturers who need reliable fasteners for general-purpose assembly in industries such as machinery, electronics, and sheet metal work. The M4 size and A2 stainless steel make it suitable for both indoor and mildly corrosive environments.

Tips

Use a torque wrench calibrated for M4 A2-70 screws to avoid over-tightening, which can strip the socket or damage the flange. For outdoor or marine environments, consider A4 stainless steel for even higher corrosion resistance.
