High Strength Hexagon Nuts For Steel Structures

High strength hexagon nuts for steel structures have relevant industry standards. Xiaoguo® undergoes rigorous quality inspections before shipment to ensure compliance with these standards, guaranteeing product quality.

We test each batch of products according to standards such as ASTM and ISO. These tests include proof load testing, Brinell or Rockwell hardness testing, and material chemical composition analysis.

Tracking using batch numbers and factory certificates is standard practice. For critical projects, we can also provide third-party inspection reports to ensure product compliance.

Regular inspections

The high strength hexagon nuts for steel structures are made to last, but it’s a good idea to check them now and then,especially if they’re in places that are corrosive or shake a lot.

Just take a look to see if there’s too much rust, if the coating is damaged, or if they’re coming loose.

Don’t put paint or sealant on them unless it’s definitely okay to do so,those could hide rust or mess with how they work.

And if a nut in a critical connection is bent, has damaged threads, or is really rusted, don’t use it again.

Compatibility

Q:Are they compatible with all ASTM A325 or A490 structural bolts?

A: Yeah, our High strength hexagon nuts for steel structures are made and designed specifically to work well with ASTM A325 and A490 structural bolts,plus their equivalents like ISO 898-1 Class 10. They follow size standards like ASME B18.2.2.

We put them through strict testing to make sure the threads fit right and lock in properly, and that they perform as they should in structural bolting setups. This makes sure the connection is strong enough and works reliably when it’s being pulled or pushed.
