A safety hasp lock is simply a device that clamps a steel bar to securely connect two objects. Hui Anquan’s hasp locks are easy to install, convenient to use, safe, sturdy, vibration-resistant, and highly durable. They can be opened and closed repeatedly without losing performance.
Why does material thickness matter?
The thickness of the lock plate is critical—it determines whether the lock can resist deformation under stress. Standard hasp locks typically range between 1.5 mm and 3.0 mm. Anything thinner than 1.2 mm is non-standard and poses a safety risk.
- Truck hasp locks: made from high-temperature forged steel, thickness 3–5 mm.
- Vibration-resistant hasp locks: require flexibility and adjustability, thickness around 3 mm.
- Outdoor moisture-resistant hasp locks: made from 304 stainless steel for corrosion resistance, thickness 1.5–2.5 mm.
We are a manufacturer and supplier of insulated quick locks, quick locks, and safety locks.
How to tell a good hasp lock from a bad one?
- Surface finish
High-quality locks are made with premium plates, giving them a smooth finish. After electroplating, the surface remains glossy and even. Poor materials produce uneven surfaces that electroplating can’t fix—leading to bubbling, discoloration, or roughness. - Workmanship
Reliable manufacturers always remove burrs and sharp edges, making products safe to handle and visually neat. Cutting corners by skipping this step reduces costs but creates locks that can scratch or injure hands. - Material thickness
Quality locks use thicker materials, making them stronger, longer-lasting, and more resistant to damage. Inferior products are thinner, weaker, and prone to deformation or breakage after short use.
