Hex Bolt Manufacture offer low prices. The hex bolt is a type of fastener consisting of a head and a screw (a cylinder with an external thread). It needs to be matched with a nut to fasten and connect two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. So what should you pay attention to before using the hex bolt?
Hex bolts introduction:
1. Correctly select the product: Before use, confirm whether the mechanical properties of the product can meet the needs of use, such as the tensile strength of the hexagonal cup head screw and the guaranteed load of the nut. The length of the hexagon socket head screw should be properly selected to tighten the nut and expose the nut 1-2 teeth.
2, check whether the thread is rough before use, whether there is iron filings or dirt between the threads, these things often lead to lock.
3, the fastener can be lubricated before use: it is recommended to use butter, molybdenum disulfide, mica, graphite or talcum powder for lubrication, the current use of wax treatment to do lubrication and anti-lock.
4, pay attention to the use of:
a. The speed of the screwing should be appropriate. Do not use it too fast. Use a torque wrench or a socket wrench as much as possible to avoid using an adjustable wrench or an electric wrench. Too fast will cause the temperature to rise rapidly and cause lockup. Imported pump valves.
b. The direction of the force applied, the nut must be screwed perpendicular to the axis of the screw.
5, the use of gaskets can effectively prevent the problem of over-tightening.
6, lock or bite often occurs in stainless steel, aluminum alloy and titanium alloy fasteners, these metal alloys have anti-corrosion properties, will produce a thin layer of oxide on the metal surface when the surface is damaged To prevent further rust. When the stainless steel fasteners are locked, the pressure and heat generated between the teeth will damage the oxide layer, causing blockage or shearing between the metal threads, and adhesion will occur. When this phenomenon continues, the stainless steel fasteners will be completely locked and will no longer be able to be removed or remain locked.
The above is about the strong knowledge of the hex bolt manufacturer, I hope to give you a reference when choosing a hex bolt. If you want to know more about hex bolts and Square Bolt, or if you want to buy a batch of high-quality hex bolts, please come to us and Plit will be happy to help you.
