Solid hardware

Great for automotive applications. They hold up well under engine vibration. Only minor issue was the packaging was a bit flimsy.

Perfect for my machinery repair

These washers fit perfectly on my M8 bolts. The 304 steel quality is evident, and they provide excellent tension to keep everything secure.

High quality stainless steel

Used these outdoors on a garden project. No signs of rust after three months of exposure to rain. Highly recommend the 304 option.

Good value for money

Bought the assorted pack for general household repairs. Most sizes are very useful, though I wish there were more M4 washers included.

Essential for any toolbox

I keep a box of these in my workshop. Having various metric sizes available saves so much time during assembly projects.

5 FAQ

Q: What is the difference between the 201 and 304 steel options?

A: 304 Stainless Steel offers superior corrosion resistance and is better suited for outdoor or marine environments, while 201 is more cost-effective for indoor dry applications.

Q: How many pieces are in the M6 pack?

A: The quantity varies by seller option selected at checkout. Typically, our bulk packs contain 100 pieces per size, but please check the specific dropdown menu for exact counts.

Q: Can these be reused multiple times?

A: Spring lock washers are generally designed for single use as they may lose their tension after being compressed and released. For critical applications, we recommend using new washers.

Q: Is the M12 size thick enough for heavy-duty truck suspension?

A: While these are high-quality washers, heavy-duty suspension systems often require specialized hardened washers. Please consult your vehicle's manual or a mechanic for specific load requirements.

Q: Do these washers come in imperial sizes like 1/4 inch?

A: No, this specific listing is for metric sizes ranging from M3 to M24. We do have separate listings for imperial sizes if you search our store.
