Stainless steel cross recessed pan head self tapping screws: it refers to the head of pan head screws, which is round or oval-head called the stainless steel self-tapping screws. Fastening material for the connection between the role of the product, but also the role of the different connections between the material and the material. Or to the locking stable material. Do not hit bottom hole and tapping in the teeth when used directly with the tool can be screwed into the lock products. Stainless steel self-tapping screws in the drill cuttings out of the matrix no teeth. Because stainless steel self-tapping screw thread and general different, head for the pointy teeth from the relatively large stainless steel bolt type, with no crumbs bit like wire tapping, tapping can not be directly screwed into metal and plastic typically use this method connect. Stainless steel pan head self tapping screws from M2 to M8's specifications are basically spot. And the customer material requirements for high temperature, corrosion, high strength grade, anti-rust. You have to use stainless steel SUS304 or SUS316 pan head self tapping screws. Flange Usage Note: Use piped liquid, gas, coupled mostly flange connection. To be able to (anti-corrosion, high-altitude, illegal channels, etc.) to reduce the frequency of replacement models Heze stainless steel bolts under special conditions, the need to use a good anti-corrosion stainless steel flanges or PVC plastic and other materials Liaocheng stainless steel bolts model, then we should use Stainless steel fasteners (screws, nuts) to join and fixed. The main characteristics of the flange connection: 1.1 screws, nuts firmly locked in the pre-process time can cause cause uneven flange faces are not parallel (Figure 1). Ie: with screw locking flange is not perpendicular to the direction of Yantai stainless steel bolts models, resulting in the role of surface screw and nut threads are not in full contact. 1.2 In order to ensure a good seal, will increase the rubber gasket between the two flanges, when the locking torque force reaches safety security, but there is still a gap between the flange and rubber gasket, the operator will often continue to firmly lock causing the locking force exceeds safe torque. 1.3 During installation, there is often a hole is not on the top and bottom flanges or some eccentric (screw mounting holes can not be passed), forced threaded mounting screws can cause the appearance of injuries, plastics, iron and other debris can fall into the screw and screw cap screw them.
