Bolts secure permanent connections using nuts or threaded holes to handle heavy structural loads, while screws fasten directly into wood or metal without additional hardware. Given Saudi Arabia’s extreme heat and humidity, we recommend SASO-compliant hot-dip galvanized or stainless steel options to prevent rapid corrosion.
For Saudi coastal zones with salt-heavy air, choose 304 or 316 stainless steel bolts, or hot-dip galvanized fasteners with at least 55 microns of zinc coating. Cold galvanization lacks durability in humid conditions. All recommended options comply with Saudi standards to ensure long-term structural integrity against corrosion.
Grade 4.6 handles light to medium loads for general assembly, whereas Grade 8.8 offers significantly higher tensile strength for dynamic forces and heavy metal frameworks. For Saudi structural steel projects, Grade 8.8 is the industry standard. Matkel provides certified high-grade fasteners with full technical documentation for stress-loaded applications.
We offer a comprehensive manufacturing defect warranty with timely replacement coverage and fully compliant ZATCA tax invoices including standard VAT. Matkel supports both wholesale and retail orders with competitive per-kilogram pricing. Our technical team calculates exact quantities to prevent project delays and material waste.
Use hot-dip galvanizing for outdoor structural frames and zinc plating for indoor applications. Avoid mixing dissimilar metals to prevent galvanic corrosion, and inspect fasteners regularly in industrial zones. Proper storage and periodic maintenance minimize degradation, ensuring hardware performs reliably across Saudi construction sites.
