High strength double ended self locking washers don’t look like regular flat washers. These ones are round, with two ends bent up—and that’s why they’re called “double-ended.” When you tighten the bolt, those bent ends press into both the bolt and the surface, which helps keep the bolt from getting loose.
Crafted from thin, flat sheets of metal—like carbon or stainless steel—they are designed to ensure a snug fit against the part.And since they aren’t thick, they fit easy in tight spots where bigger washers just won’t work.
Some have smooth edges so they don’t scratch things, while others have a rougher surface to grip better. They come in all the common bolt sizes too, so they work for most cases.
High strength double ended self locking washers cost less than a lot of other locking parts—like those special locknuts or hydraulic setups. They’re really easy to make, mostly just stamped out of metal, so production doesn’t cost much. That’s why they’re cheap to buy.
Whether you’re a small workshop or a big factory ordering a bunch, you’ll save money compared to getting other kinds of locking hardware.
You don’t need any fancy tools to put them in either—a basic wrench does the job. So no extra costs for special tools. Even if you compare them to using a regular washer plus something like a cotter pin, these often end up cheaper because they do two things at once.
And even though they’re not expensive, they still lock things securely. That makes them a practical, budget-friendly choice for most jobs.

A:These high-strength double-ended self locking washers can be used over and over, handle vibration really well, and still work in both hot and cold conditions. They’re a budget-friendly option since you can reuse them, unlike one-time solutions like threadlocker or crush washers.
