The importance of corrosion-resistant screws in industrial and construction projects
What is a corrosion-resistant screw and how is it different from a normal screw?
- Materials: use of stainless steel (stainless steel) or special alloys instead of plain carbon steel
- Protective coatings: such as hot-dip galvanized, dichromate, zinc-nickel or polymer coatings
- Quality control and standards: higher sensitivity on thread tolerance, hardness, corrosion tests and compliance with standards project
Determining factors in the selection of corrosion-resistant screws
1) Environmental conditions and corrosiveness class
2) Type of loading and sensitivity of the structure
3) Compatibility of cover with assembly and tightening torque
4) Risk of galvanic corrosion
The best materials for corrosion resistant bolts and nuts
Stainless steel screwdriver
Carbon steel with hot dip galvanized coating
Advanced industrial coatings (dachromat and similar)
Common coatings to increase corrosion resistance
Zinc plating and combined plating
Polymer coatings and industrial paints
Standards and quality control in the sale of corrosion-resistant screws
- Certainty of resistance class and compliance with project requirements
- Dimensional control of thread and tolerances
- Uniformity of coating and no flaking or cracking
- Product traceability (Batch/Heat) in sensitive projects
- Providing technical documentation and quality control reports if required by the project
How to guarantee a competitive price without losing quality?
- Instead of focusing solely on price, focus on “cost of ownership”; It means durability, reduction of repairs and reduction of stoppages
- Ask the supplier for brand diversity and the possibility of offering several options according to the budget and installation environment
- Trust the supplier's expertise in choosing the right material/coating, not just stock
- Make sure that the goods in terms of size, thread, length and standard match the plan and project specifications
Common mistakes when buying corrosion resistant bolts and nuts
Choosing an inappropriate cover with the environment
Ignoring compatibility with the material of the main part
Not paying attention to the uniformity of the coating and the quality of the thread
