Heavy Duty Blind Bolt

Heavy Duty Blind Bolt — a specialist fixings solution for joining heavy-weight steel sections where standard blind bolts are unsuitable. Engineered with a shorter profile and expanding base, the HD bolt delivers superior performance when shear forces act across bolt legs. The unique pin-locking mechanism ensures secure, reliable connections without specialist installation equipment.

Key Features

• Expands and locks securely without costly specialist tools — activation requires only a hammer and spanner
• Shorter profile designed specifically for applications where shear planes cross bolt legs
• No oversized hole required — installs into standard-sized apertures
• Zinc flake coating provides 1000 hours salt spray protection for corrosion resistance
• Simple, fast installation reduces labour time and assembly costs
• Unique pin-locking design ensures permanent connection integrity

Typical Applications

Ideal for structural steelwork, fabrication, heavy engineering and installation work where space is limited or where conventional blind bolts cannot provide adequate shear strength. Commonly used in bridge work, heavy machinery assembly, and large-scale structural connections.
