Washers come in handy when you want to tighten, distribute pressure or prevent leakage in joints, nuts, and axle bearings. This Lock Washer Vs Flat Washer review looks at the main features to look for in lock and flat washers.

I work with all sorts of washers in my steelworks business. At the beginning of my business, I did not put much thought into the quality of washers I used. As long as they tightened a joint then there was no problem. Problems started when the cheap washers started failing in their job. Most washers would break and become useless during assembly. Some washers worked fine until a few months later my clients came back with complaints. I realized that washers, no matter how abysmal they are, play an important role in the final products. I started focusing on high quality lock and flat washers from then.
