Zinc Blue Through Hole Hexagonal Rivet Nut

The specifications for Zinc Blue Through Hole Hexagonal Rivet nut mainly focus on the internal thread size and the outer diameter.Thread sizes range from M3 to M10, which are the most common for sheet metal assembly work. The outer diameter matches the thread size—smaller threads pair with smaller diameters to fit pre-drilled holes properly. You just need to pick based on the bolt you’ll use with it.

Grades are simple: standard grade and high-strength grade. Standard grade works for regular tasks, like furniture brackets, electronics casings, or light-duty sheet metal projects. High-strength grade is made of thicker material, suitable for machines or parts that need to bear more force without slipping or breaking.

Each nut’s spec and grade are clearly marked on the packaging label, so it’s easy to pick the right one. No complicated coding, just basic numbers and words. Zinc Blue Through Hole Hexagonal Rivet nut’s specs and grades cover most common assembly needs, no extra fancy options.

Product quality control

We start with raw material checks. Every batch of metal is inspected for cracks, dents, or uneven thickness. Only qualified materials enter production—this step ensures the base quality won’t have issues.

During production, spot checks are done regularly. We first check thread accuracy; they need to fit bolts smoothly without tight or loose spots. We also measure outer diameter and hexagonal size often to match standard specs. Surface treatment is inspected too, making sure there are no missing plating areas or thin coatings that could cause rust.

Before shipping, random samples from each batch go through installation tests. We press them into sheet metal and test if they lock firmly without slipping. We also check for surface scratches or deformities. Zinc Blue Through Hole Hexagonal Rivet nut goes through these simple but strict steps to ensure it works well for daily assembly jobs.

Q&A Session

Q:How long does the zinc-plated surface last outdoors?

A:Zinc-plated ones last about 1-2 years outdoors in normal weather. If it’s a humid or coastal area with salt mist, the lifespan may shorten. For outdoor use, we suggest hot-dip galvanized or stainless steel versions—they can last 5-8 years. The zinc plating is good for indoor or covered outdoor spots, like workshops or under eaves.
