Product Introduction

Hex socket head cap bolts that are galvanized have excellent anti-corrosion properties, and they are extensively used in different metal structural facilities in various industries. The process of galvanizing involves immersing these bolts, which have already been rust-removed, in a hot molten zinc solution of approximately 500°C. Alternatively, electroplating can also be used to attach a zinc layer to the surface of DIN912 hex socket screws, all to achieve the objective of anti-corrosion.

 

Advantages of Galvanized Allen Bolts

Galvanizing offers a cost advantage over alternative coatings due to its low processing cost.

The hot-dip galvanized anti-rust coating is known for its remarkable durability even in suburban environments. Its effectiveness can be maintained for over 50 years without the need for repairs. This anti-corrosion method is widely used in various industries for metal structure facilities, making it a reliable choice for long-term use.
