flat washer

 

How to ensure flat washer quality?

Each batch of goods is double-checked by manual + machine, and unqualified ones are directly eliminated! Just like the calculations for an exam, each of our washers must pass a "physical examination". Those with wrong sizes and burrs are not accepted!

What are the flat washer product advantages?

Rust-proof: not afraid of soaking in water (galvanized models are like putting raincoats on washers) Wear-resistant: not afraid of scratches when tightening screws (the surface is smoother than a mobile phone screen) Pressure-resistant: even a fat master will not be flattened when standing on it! (Exaggerated, but it is indeed strong in load-bearing)
