Tired of weak threads and unreliable fastenings in steel or thin-walled materials? Our Flat Head Serrated Open End Rivet Nuts are engineered to deliver unmatched grip, strength, and longevity. Designed for high-performance fastening, each nut insert features a serrated flange that locks in tight, preventing rotation even under heavy stress or vibration.

These blind rivet nuts are ideal for engineers and production teams working in automotive, aerospace, and industrial manufacturing, where precision and durability are critical. The flat head design offers a flush surface finish, while the open end allows for longer bolt engagement and added versatility—perfect for both structural and cosmetic applications.

Manufactured from high-quality steel, these rivet nuts are your go-to choice for metal assemblies where welding isn’t practical and speed matters.
