Engineered for High-Torque, Blind-Hole Fastening in Sheet Metal & Hollow Structures - knurled thread insert
In demanding industrial assemblies where backside tool access is impossible, standard fasteners often struggle with inconsistent deformation, stripping, or loosening under cyclic vibration. Engineered with advanced cold-forging expertise and stringent quality controls from Taiwan, our new Breakaway Blind Rivet Nuts deliver an exceptionally reliable, high-retention threaded anchoring solution for lightweight structural metals, tubing, and thin-gauge enclosures.
Featuring precision-engineered shear grooves and a stepped expansion body, this fastener is designed to fracture and deform uniformly along predetermined stress lines during installation. The resulting wide-footprint backside flange distributes load symmetrically across the parent sheet, significantly increasing pull-out resistance while preventing localized substrate cracking on delicate or thin-walled components.
Key Features
Controlled Radial Deformation: The proprietary breakaway groove ensures repeatable, uniform collapsing on blind-side assemblies, eliminating incomplete setting defects across high-volume production lines.
Superior Spin-Out Resistance: Deep external knurling or optional hexagonal body geometry mechanically bites into the base material, providing exceptional torque-to-turn performance even in slippery pre-lubricated panels.
Extended Grip Range: A single part number covers multiple panel thickness variations, allowing procurement teams to consolidate SKUs and streamline assembly inventory.
