A brief introduction to the fixing screws of sheet metal stamping parts

Stamping parts processing factory, processing various metal stamping parts, the following briefly talk about the knowledge of sheet metal stamping parts fixing screws; sheet metal stamping parts are directly punched or tapped on the plane using self-tapping screws, and self-tapping screws are triangular self-tapping screws. Preferably, the problem of slippage will not occur. But the driving force will be heavier than non-triangular self-tapping screws; if the screw is 3mm in diameter, the aperture d should be between 2.4~2.5mm; if the screw is 4mm in diameter, the aperture d should be 3.4~3.5 mm; punching or tapping on the plane of the sheet metal stamping parts, tapping with screws, tapping M3 or M4 mechanical teeth; if the diameter is 3mm screw, the aperture d should be 2.6mm before tapping ; If the diameter of the screw is 4mm, the hole diameter d should be 3.6mm before tapping; the sheet metal stamping parts are punched on the plane of the riveted fixed nut, and the hole diameter d of the riveted fixed nut is recommended by the manufacturer The size is the benchmark; the article recommends: the connection method of sheet metal stamping parts Previous: Deep drawing stamping process of stamping parts
