What is a self-tapping screw? In the usual sense, a self-tapping screw is a threaded fastener that does not need a pre-tapped internal thread. When the screw is driven into a smooth, untapped hole, it cuts its own internal thread, so a relatively high torque is required. The mating part is normally a soft material such as plastic or an aluminum/magnesium alloy. Self-tap...
In the blow-feed structure of existing blow-type screw feeders, a feed tube is usually used as the conveying channel for screws. When the screws being conveyed are relatively large, any slight bend or deformation of the tube can cause the screw tip to butt against the tube wall and jam. Likewise, an incorrectly sized tube, a material that is too soft, or an unreasonable ...
In the four main automotive processes, body-in-white (BIW) welding is a key step. With lightweight bodies, more and more bolts are being tightened right inside the welding line. However, body stampings are large and curved; part-to-part variation is high, and welded sub-assemblies shift, so threaded holes are often off their nominal position. Previously the typical cure...
In most mechanical products, screw fastening is the commonest way to join parts. TV sets, mobile phones, cameras and other electronic devices use large quantities of screws whose nominal diameter is below 5 mm, and “screw float” (the head stands off the surface) is a frequent defect.
