Hardware knowledge: the role of hardware anti-theft screws and nuts

With the improvement of our living standards, our material life is also constantly improving, but while improving, our anti-theft concept is also constantly improving, especially in our hardware industry and automotive fastener industry. It is the industry that is most likely to be stolen. The cost of bolts and nuts on cars is basically very high. It is also the place where these thieves first start. In order to be able to better ensure that the bolts and nuts on our cars are not stolen by someone who wants to.

The current concept of a new type of fastener polygonal shape that breaks the conventional standard uses a tapered external thread to cooperate with a special tool, which can only be tightened clockwise, and the tool will fall off if the force is removed counterclockwise. . The tapered shape effectively avoids the possibility of disassembly with a pipe wrench, thereby achieving a better anti-theft and disassembly effect. Even if it is loose for a long time, it can continue to be tightened, thus meeting the customer's requirements.

The functions of anti-theft bolts and anti-theft nuts can be divided into: (Guide: Cold heading and threaded fastener processing)

1. To safeguard the interests of merchants, merchants use anti-theft bolts on their products. For example, the anti-theft bolts used in many products are mainly used to prevent users from disassembling the product casually and to better find out the cause in the maintenance of the product.

2. Anti-theft function. In many outdoor products, anti-theft bolts are used, because there are many defects in management in the outdoors, and the use of anti-theft bolts greatly reduces unnecessary losses. For example: anti-theft bolts are widely used in outdoor guardrails.

3. Easy to use, it can be installed with a special wrench, no special and complicated tools are needed. The manufacturer will provide special tools to customers, so there is no need to worry about installation problems.

Anti-theft bolts and anti-theft nuts are nuts and bolts with anti-theft effect, because they are often stolen through the use of ordinary screws when used outdoors, and the use of anti-theft hardware products can largely avoid theft. Therefore, the use of anti-theft can greatly reduce unnecessary losses. Moreover, the anti-theft hardware products are very convenient to use, and can be installed through a special wrench without the use of complex tools.

The advantages of using anti-theft nuts and anti-theft bolts are:

1. It can prevent personal injury and property loss caused by human theft, and spend little money to ensure the safety of facilities.

2. Higher cost performance, more wear-resistant, corrosion-resistant and durable than ordinary nuts.

3. The special wrench does not cause the nut and the sliding wire to be uneven due to improper use of the tool.

4. The anti-theft nut is a one-time molding product, because the radial size of the blind groove gradually becomes smaller, the internal balls are stuck in the thread, which plays a very good anti-theft effect, and its internal is equipped with a special plastic inner bushing Plastic washers are used to ensure the free movement of the balls.
