Stainless steel bolt processing parts

The processed stainless steel bolt is the bolt that will stick out and retract when the lock cylinder is turned with a key.

Bolt material

As an important load-bearing component, the lock tongue has strict requirements on the firmness of the material. Our common bolt materials are zinc alloy, stainless steel and so on. Generally speaking, compared with zinc alloy materials, stainless steel performs better in strength and is not easily deformed by impact. In addition, stainless steel also has the characteristics of corrosion resistance and high temperature resistance.

Oblique tongue, square tongue

The oblique tongue has a spring component, and criminals can easily push the oblique tongue back with a card to achieve the purpose of unlocking. The safety performance is worrying. If you only rely on the oblique tongue to prevent theft, without performing operations such as reverse lock, the card unlocking and burglary you have heard of may be staged in real life.

Compared with the diagonal tongue, the square tongue has no spring components and will not retract due to external forces such as card squeezing. All the lock bodies used by the Zhichang smart lock have a square tongue, combined with the anti-lock function, which is convenient to use.

Single bolt, multiple bolts

The number of bolts may vary depending on the lock body, and there are single bolts and multiple bolts. Compared with a single bolt, when multiple bolts are opened violently, opening one bolt will not cause a fatal blow to the anti-theft function. The main bolts of Royal Golden Shield smart locks are all three bolts. With anti-saw and anti-collision functions, it can effectively prevent violent unlocking.
