Questions & Answers

What size are these nyloc nuts?

They are 5/16" imperial nyloc nuts, supplied in a pack of 15.

How does a nyloc nut stay tight?

A nylon collar inside the nut grips the bolt thread, creating friction that resists loosening from vibration and movement.

What are they made from?

Zinc plated steel hardware with a silver finish, suited to indoor use and areas not exposed to direct weather.

Can nyloc nuts be reused?

The nylon insert works best on first fit. They can be reused a limited number of times, but replace them once the insert no longer grips firmly.

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.

Great value for money

Spent a while looking for the right Zenith 5/16" and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.
