Countersunk Hollo-Bolt®

Countersunk fasteners for structural steel are essential components in modern construction, particularly for connecting Structural Hollow Sections (SHS) and hollow steelwork. These specialized fasteners feature a unique countersunk head that sits flush with the steel surface, significantly reducing protrusion and enhancing both aesthetics and safety on construction sites. The installation process is straightforward, requiring the fastener to be inserted into pre-drilled holes and tightened with a torque wrench to establish a secure connection, making them an invaluable asset on any job site.

Key Features

• The countersunk head design ensures a flush fit with the steelwork, ideal for applications where aesthetics matter.
• They are perfect for blind connections, especially when site access is limited.
• The quick installation process minimizes on-site labor time and disruption, making them efficient for contractors.
• Engineered for reliability, these fasteners are suitable for structural applications demanding high strength.
• Reducing protrusion contributes significantly to enhanced safety, particularly in environments where personnel operate.

Typical Applications

Countersunk fasteners for structural steel are widely used in various structural steelwork applications, including bridges, multi-storey buildings, industrial fabrications, and plant installations that require robust hollow section connections. Their design is particularly beneficial when standard bolting methods present challenges due to limited accessibility, or when a clean, polished appearance is required.

Technical Information

For optimal performance, it is important to ensure pre-drilled holes are available in the hollow section before installation. Proper tightening should be conducted using a calibrated torque wrench to achieve the necessary connection strength. It's essential to consult the technical data for the specific grade, size, and torque specifications related to your application to ensure safety and functionality. Overall, countersunk fasteners for structural steel represent a reliable choice for modern engineering challenges.
