Missing a few sizes
Mostly complete kit but my box was missing some of the 1/4 inch spring washers. The nuts themselves are good quality though.

Perfect for my workshop
Great assortment of nuts and washers. The separation between 304 and 316 is clearly marked which saves me time on projects.

Good quality steel
Solid nuts and washers. The threads are clean and fit well. Only reason for 4 stars is the latch on the box feels a bit flimsy.

Well organized
The box is sturdy and compartments are sized correctly. Makes finding the right washer very easy during assembly.

316 grade is legit
Used for outdoor railing installation. No signs of rust after several months of exposure to rain. Highly recommend for exterior use.
Q: Does this come with a storage case?
A: Yes, all nuts and washers are organized in a durable, compartmentalized plastic storage box included in the package.
Q: Can I use the 316 stainless steel for saltwater applications?
A: Yes, 316 stainless steel is recommended for marine environments due to its higher resistance to chlorides and corrosion.
Q: Is this kit metric or standard imperial sizes?
A: This kit is strictly US & Imperial Standard (UNC/UNF). We do not carry metric sizes in this specific assortment.
Q: What is the return policy if sizes are missing?
A: We offer a 30-day return window. If pieces are missing, please contact support for a replacement or refund.
Q: Are the washers hardened steel or standard stainless?
A: The washers are standard stainless steel matching the grade of the nuts (304 or 316). They are not hardened steel.
