Extreme anti-rotation rivet nuts with cross knurl & barbs. 316 stainless steel, 70% thread depth. Withstands 20G vibration. M6-M12 sizes. Electropolished. DNV-GL & MIL-STD-1312 certified.
Engineered for high-shock environments, these rivet nuts combine cross knurling (0.5mm depth) and radial barbs for maximum anti-rotation. The 90° flat head provides aerodynamic sealing, while the electropolished 316L body resists salt spray corrosion. Partial threads (70% depth) maintain tensile strength with 30% weight reduction. Exceeds MIL-STD-1312 vibration standards.
