Delta Fitt Inc is the best Blind Bolts Manufacturer providing fastening solutions for locations where backside access is restricted during fitting. They are designed for single-side entry and ensure great holding power by using an expanding mechanism that fits tight against the structure. They are manufactured for fitting in hollow sections, structural beams, and sealed fittings, making them welding and tap-free from the other side. Blind bolts have the reputation of minimizing installation time with consistent strength in load-bearing applications within infrastructure, equipment, and fabrication systems.

Utilized in high-demand B2B engineering and construction industries, blind bolts provide consistent performance within bridges, modular enclosures, and steel structures. With high vibration and environmental stress resistance, they can be applied in dynamic assemblies. Produced in different lengths, diameters, and finishes, they are compatible with composite, aluminum, and steel structures. Their accurate anchoring system is for secure and durable connections in overhead and tight installations. We supply Anchor Bolts engineered to securely fix structural elements to concrete, ensuring strong and stable foundation connections.

Blind bolts are special mechanical bolts that are used where the only access is on one side of the joint. They find extensive applications in construction, automotive, aerospace and heavy engineering industries where conventional nuts and bolts cannot be fitted at the rear. Blind bolts are used to offer good and secure clenching in hollow sections, tubes, and closed profiles to guarantee high load bearing, vibration-free, and structural stability.

These fasteners come in different materials like stainless steel, carbon steel and alloy steel to accommodate the different environments and load conditions. Blind bolts are easily installed, less labour-intensive and have a uniform performance in comparison to the traditional fastening techniques. They offer a perfect solution to contemporary fabrication, maintenance, and retrofit projects that need reliable single-sided fastening due to their corrosion resistance, ease of use and provision of secure joints.
