Good but tight

Quality is good but the M6 size was a bit tight on standard bolts. Still usable.

Solid Construction

These nuts fit perfectly on my project. The serrated base really helps keep them in place.

Workshop staple

I keep these in stock for all my repairs. The flange saves time not using separate washers.

Exactly as described

Needed 316 grade for outdoor use. These seem to hold up well against moisture.

5 FAQ

Q: Will these rust outdoors?

A: 304 and 316 grades offer high rust resistance but 316 is better for saltwater exposure.

Q: Can I buy in bulk?

A: Yes please contact us for wholesale pricing on large orders.

Q: Do I need a separate washer?

A: No, the integrated flange acts as a built-in washer.

Q: What is the difference between 304 and 316?

A: 316 offers higher corrosion resistance suitable for marine environments.

Q: Are these metric or imperial?

A: These are metric thread sizes ranging from M3 to M16.
