The Flush Break Maxi Fastener (MGB) is a heavy-duty, two-piece fastening system specifically engineered for structural applications requiring strength, durability, and tamper resistance. Commonly recognised as a Huckbolt-style fastener, the MGB is designed with a multi-breakneck pin that provides a wide grip range, significantly reducing the need for precise grip length selection and minimising the risk of rework. This flexibility also simplifies inventory management by accommodating varying material thicknesses with fewer fastener sizes.

Once installed, the fastener delivers a clean, flush break finish, making it ideal for applications where surface smoothness, safety, and professional appearance are important. The flush break design also allows for easy visual inspection, ensuring correct installation every time. Manufactured from Grade 2 material, the MGB offers high tensile and shear strength while maintaining ductility for demanding industrial environments.

As a permanent Huckbolt alternative fastening system, the MGB is specifically designed to resist vibration, tampering, and loosening over time, making it a reliable solution for industries such as mining, construction, transport, rail, and steel fabrication. Its robust locking mechanism creates a secure, maintenance-free joint capable of performing in high-stress applications.

The Flush Break Maxi Fastener is compatible with Swagefast’s hydraulic and pneumatic installation tooling systems, allowing for fast and efficient installation. Combining strength, adaptability, and ease of use, the MGB fastener is a trusted solution for high-performance permanent fastening requirements where traditional bolts or rivets may fail.
