Splined Threaded Insert

Splined Threaded Inserts provide a high-strength fastening solution for creating permanent threads in thin materials while offering increased resistance to rotation. At Panther Pro, our splined threaded inserts feature a ribbed body that grips securely into the parent material during installation, making them ideal for automotive, agricultural, marine and industrial applications where vibration and torque resistance are essential.

The splined body bites into the surrounding material as the insert is installed with a compatible rivet nut tool, helping to prevent the insert from spinning under load. Designed for use in sheet metal, box section and other thin materials, splined threaded inserts create strong, reusable threaded fixing points for bolts and machine screws, making them ideal for vehicle bodywork, fabricated assemblies, machinery, equipment repairs and production environments.

Available in a range of thread sizes and grip ranges, our splined threaded inserts are engineered to provide dependable performance in demanding environments. Browse the Panther Pro range below to find the right splined rivet nuts for your next fabrication, repair or manufacturing project.
