Rust resistance, thanks to high-quality stainless steel
Corrosion-resistant stainless steel resists oxidation and rust, helping maintain mechanical strength in damp or exposed conditions. The metal composition supports long-term stability without rapid degradation.
Fastenings remain reliable in kitchens, garages and outdoor fixtures, reducing the need for frequent replacements.
Secure fastening, with hex socket head cap screws and lock washers
Hex socket heads accept Allen keys for controlled torque and are less prone to cam-out; threads are clearly cut with uniform pitch for stable engagement. Lock washers add clamping force to counter loosening from vibration.
Less risk of stripped heads or parts loosening, so repairs stay tight even under movement or light vibration.
