Useful Knowledge Shared For Screws, Nuts And Bolts
Verfasst: 28.11.2022, 07:23
Screws refer to a tool that gradually tightens a part using the mathematical and physical principles of the beveled circular rotation and friction of an object. Screws are a common fastener that is widely used in daily life and production. The general material is plastic or metal, and the grooves engraved on the surface are called threads, which are cylindrical.
Screws can be divided into:
Hexagon head, hexagon head with flange, square head, T head, mushroom head, cheese head, round head, pan head, countersunk head, raised countersunk head.
One-line slot, inner triangular slot, inner corner quad slot, cross slot, rice slot, flower slot, plum blossom slot, flower one-line slot, special slot, and hexagonal slot.
Why do screws have so many head types?
1. In many cases today, one-line head screws have been replaced by cross head screws. Because the one-line head screw is more likely to be screwed so that the pattern on it cannot be seen clearly, the screwdriver cannot be used. The contact area between the one-line head and cross head type and the tool is much smaller than the contact area between the inner and outer hexagon head and the tool. Therefore, there will be no problem with distortion and failure of the inner and outer hexagons.
2. Regarding countersunk head screws and non-countersunk head screws. The bases of laptops in our lives are countersunk screws. However, due to the complexity and cost of processing, it is not necessary to use countersunk head screws on some unnecessary occasions.
Bolts are mechanical parts that is a cylindrical and threaded fastener that requires a nut. It consists of a head and a cylinder with an external thread, which needs to be matched with a nut to fasten and connect two parts through holes. The bolts can be divided into ordinary ones and those with hinged holes according to the force of the connection. According to the shape of the head, it can be divided into hexagonal head, round head, square head, countersunk head, and so on. Among them, the hexagon head bolt is the most commonly used shape.
Nuts are a part that is screwed together with a bolt for fastening and has different classifications depending on the material, including stainless steel, copper, alloy, etc.
The main difference between screws and bolts is that screws work individually. The thread matched with the screw is machined on the workpiece. But the bolt and the nut work together, and the thread matched with the bolt is machined on the nut.
They play similar roles but in different contexts. Bolts and nuts are pre-purchased standard parts, and the objects to be connected only need to punch a suitable through-hole for each connection. Screws can be used in situations where one of the objects to be linked cannot make a through-hole, then screw links can be used.
KENENG is a custom screw manufacturer. Customized fasteners are available for special lengths, and tolerances regarding length or body diameters. Or due to certain strength requirements or corrosion situation requirements, these special cases may require special materials. In many of these situations, the customer’s engineering department will provide a CAD drawing showing all aspects of the fastener required for the company’s production. To guarantee high quality, KENENG has more than 500 sets of production and testing equipment, which are imported from Japan, Switzerland, America, and Taiwan, including cold forming, CNC, stamping, hot forging, turning, and cold drawing, heat treatment, and plating lines. We can undertake large quantities of orders, and ensure the quality of products and delivery time. Consistent purpose to price as the vanguard, service as the core, quality as the leading. Welcome to contact us and cooperate with drawings and samples.
