Product Overview
Press Nuts are permanently installed threaded inserts engineered for thin sheet metal applications. Utilizing a precision cold-forming press-in process, they create robust and reliable internal threads directly into panels, eliminating the need for welding or loose hardware. Ideal for enclosures, chassis, racks, and assemblies requiring removable access panels.
Key Advantages
Single-Sided Installation: Requires access from only one side of the workpiece.
High Torque & Push-Out Resistance: Full 360° annular deformation ensures superior retention strength.
Anti-Rotation Feature: Knurled or multi-lobed shanks prevent spinning during fastener mating.
Clean Installation: Cold-forming process produces no chips or debris.
Sealed Versions Available: Optional closed-end and waterproof designs (IP67).
