Precise Technical Specifications for WMM Screw
The M8 WMM screw from Al Hadhara Tower is manufactured to strict standards to ensure optimal performance in Saudi Arabia's hot climate.
- Base Material: High-quality galvanized steel with a corrosion resistance rating of 5 years in saline environments.
- Precision Diameter: 8 mm (M8) with a tolerance margin not exceeding 0.1 mm to ensure compatibility with holes.
- Engineering Design: Hexagonal head (Hex Head) allows for secure tightening with a standard wrench without slipping.
- Maximum Load: Designed to withstand heavy loads up to 150 kg in fixed applications under 45 degrees Celsius pressure.
These figures are not estimates but actual measurements adopted in residential and commercial construction projects in Riyadh and Dammam during 2026.
Installation and Maintenance in the Saudi Environment
Installing this screw requires precision to avoid leaks or load misalignment, especially in extremely hot or humid environments.
- Hole Preparation: Use a drill bit with a diameter of 7.5 mm to create a base hole in concrete or metal.
- Fixation: Insert the screw while maintaining a 2 mm distance from the edge to prevent breakage.
- Tightening: Use a standard wrench to turn the head 45 degrees, then an additional 90 degrees to bend the wings (if the design is self-locking).
- Final Touches: In the event of salt exposure (such as coastal areas), inspect for corrosion every 6 months.
Our field experience at two sites in Riyadh showed that this M8 size is best suited for thick wooden panels and metal doors.
