Usage: The necessary spare parts for the installation of highway wave guardrails – bolts,Due to the rampant construction of highways, the wave guardrail has entered the public’s field of vision, but the small parts of the wave guardrail also play an important role. With the frequent theft of high-speed public facilities in recent years, which seriously endangers driving safety, many manufacturers have developed new products to replace the shortcomings of previous products, and anti-theft screws can make up for this defect.

Guardrail anti-theft screws, also known as S-type anti-theft screws, have been widely used in guardrails. The features of this anti-theft screw are:
1. Easy to use. Just use a special tool to tighten with ordinary screws.
2. The anti-theft effect is good. The guardrail anti-theft screw only has a force point in the positive direction, and there is no force point in the reverse direction. Once installed, it cannot be disassembled.
3. The appearance is beautiful and generous. The color of the anti-theft screws is the same as that of the guardrail, which can be well matched with the main body.
4. Not removable. So as to achieve the purpose of not easily stolen.
In addition: there are eccentric hole anti-theft screws in the market now, which make up for the feature that the guardrail anti-theft screws cannot be disassembled and installed. Generally, ordinary screws and anti-theft screws are divided into ten levels. The strength of the national standard can reach above 8.8, and the non-standard is below 8.8.
The guardrail anti-theft screw and nut are not limited in application like ordinary screws and nuts, so their application fields are very wide, such as: electric power facilities, railway facilities, highway facilities, oil field facilities, urban lighting street lamp facilities, lamp car tires and Public fitness equipment, etc. As long as the items are fixed with screws and nuts, this technology and products can be applied to prevent unintended disassembly, preventing theft and loss, thereby strengthening the management and protection of public facilities and equipment.
