Anlock Blind Rivet In-Bolt | High-Strength Structural Blind Rivet Bolts for Industrial Applications - Fasto Fasteners
1. Product Overview
Anlock Blind Rivet In-Bolt is a high-performance, structural blind fastener designed for permanent, high-strength connections in single-sided access applications. Combining the ease of installation of a blind rivet with the robust holding power of a bolt, this innovative fastener delivers consistent clamping force, vibration resistance, and reliability for critical assemblies. Manufactured to strict quality standards, it is ideal for demanding industries including automotive, construction, aerospace, and heavy machinery.
2. Key Features & Advantages
✅ High Structural Strength
The internal bolt mechanism creates a strong, vibration-resistant joint with uniform clamping force, preventing loosening under dynamic loads.
✅ Single-Sided Installation
Unlike traditional bolts, it requires access to only one side of the workpiece, making it perfect for blind or hard-to-reach applications.
✅ Consistent Clamping & Locking
Precision-engineered internal components ensure controlled, repeatable clamp load, eliminating the risk of over-tightening or under-tightening.
✅ Corrosion Resistance Options
Available in aluminum, steel, and stainless steel variants with zinc plating or passivation treatments for enhanced rust protection in harsh environments.
✅ Wide Grip Range Compatibility
Engineered to accommodate a broad range of material thicknesses, reducing inventory complexity and simplifying project planning.
✅ Visual Installation Confirmation
The mandrel break design provides clear, visual proof of correct installation, ensuring quality control in high-volume production.
