Description

1/2″ 13 UNC Serrated Flange Lock Nut, Coated

Flange nuts or hex nuts ensure that the nut remains secure, even if the fastening surface is not uniform.

Their circular bottom flange is larger than the top hex part, which keeps the bolt from loosening over time.

Pergola World serrated flange nuts provide an excellent locking mechanism — they are perfectly angled so the nut doesn’t budge once fastened. The serrations also ensure that any movements or vibrations won’t compromise its holding power.

These flange nuts are perfect for irregular-shaped or oversized holes, as they cover all flaws. Sturdy, corrosion-resistant, and durable – they will provide the strength you need for years to come.
