Great variety pack

Having all these sizes in one order saved me multiple trips to the hardware store. The washers fit perfectly and have good spring tension.

Solid construction

These feel very sturdy. The split design provides excellent tension to keep bolts from vibrating loose. Great value for the price.

Exactly as described

Needed specific M10 washers for an outdoor fence project. These are holding up well against the elements. Very satisfied with the purchase.

Perfect for marine projects

Bought the M6 and M8 sizes for a boat repair. The 316 steel quality is evident; no rust after months of exposure to saltwater. Highly recommended.

Good quality, slow shipping

The washers themselves are excellent quality and match the specs perfectly. Only giving 4 stars because shipping took a bit longer than expected.
