Lock Washers

Protect your investments with lock washers! Most people do not know they need them until the problem is too big to fix. If you install loose fasteners on an industrial machine, for example, it is likely to break down permanently- costing you more time and money with every passing moment that the machine operates without tightening its fasteners. Lock washers are one way that can prevent this from happening by preventing nuts and bolts from loosening over time. They're easy to use, available in standards sizes 1/4" - 3/4", inexpensive, come in various sizes depending on your needs, and most importantly protect all of your vital work equipment with these simple additions! Lock washers ship free in the U.S.!

Lock Washers – Collection FAQs

1. What are lock washers used for?
Lock washers are designed to prevent nuts and bolts from loosening due to vibration, movement, or shifting materials. They’re commonly used in timber framing, machinery, furniture, gates, and any application where a secure, long-lasting hold is needed.

2. How are lock washers different from standard flat washers?
Unlike flat washers that simply distribute load, lock washers have a split or contoured design that applies tension against the nut or bolt. This tension keeps the assembly tight over time, even in high-vibration or outdoor environments.

3. How do I choose the right size lock washer?
Match the washer’s inner diameter directly to your bolt size. For structural or exterior projects, choose a washer that pairs well with our decorative bolts and washers for both performance and visual consistency.

4. What finish and texture options are available?
Lock washers can be ordered in matte black, natural iron, oil-rubbed bronze, and hand-distressed finishes. These finishes are applied in-house to help your hardware blend seamlessly with rustic or historically styled projects.

5. Are these washers hand-forged?
The washers themselves are precision-formed for reliable tension, while many decorative finishes are hand-applied by our American blacksmiths. This gives even functional hardware an authentic old-world look.

6. What are the lead times and where are they made?
Most lock washers ship within 1–10 business days depending on finish and quantity. All decorative and custom-finished washers are made or finished in the USA at our Idaho forge.
