When observing the Smooth Surface Countersunk Head Riveted Nuts from the outside, the first thing you will notice is their conical heads - the internal angle of which is standard 100 degrees or 120 degrees. This shape enables the nuts to be perfectly flush with the surface of the connected material.
The main body of these nuts either has knurled (with small protrusions) or has grooves. This prevents them from rotating during installation and also prevents them from rotating during use. Below the head, there is a solid handle. When you press this handle, it will deform outward (in a radial direction), thus forming a tight and permanent lock.
This specific shape and design not only provide an attractive appearance but also make the nuts extremely resistant to pull-out force - thus being less likely to be pulled out.
Smooth Surface Countersunk Head Riveted Nuts can save a significant amount of costs as they simplify the assembly process. They are easy to install and do not require many specialized tools - thus reducing labor costs.
If compared with welded threaded inserts or using more complex fastening systems, these nuts are cheaper in price while maintaining the same level of strength. The time saved during production, combined with the durability of the connection, makes the total cost of using head-bolted nuts very cost-effective for manufacturers producing large quantities of products.

Q: Can you provide the detailed dimensional specifications and technical drawings for your Smooth Surface Countersunk Head Riveted Nuts?
A:Absolutely. We give you full technical data sheets and CAD drawings for all our Smooth Surface Countersunk Head Riveted Nuts. These docs lay out all the key dimensions—like the head angle (usually 90° or 100°), head diameter and thickness, thread size, and grip range.
The grip range is just the total thickness of the material the nut can fasten securely. It’s important to make sure your countersunk hole lines up with these specs. That way, the nut fits flush and works as well as it should.
