Specialty Blind Rivets
GO-LOCKBOLT systems are structural blind rivets or pin-and-collar lockbolts engineered to deliver extreme vibration resistance and high shear and tensile strengths in heavy-duty connections. The installation process cold-forms a collar into the pin's annular grooves or utilizes a 100% retained mandrel, generating a permanent, tamper-proof, and uniform clamp load. This mechanism prevents loosening under severe dynamic stresses that would compromise traditional threaded fasteners. Fabricated from high-tensile carbon or stainless steel, these fasteners are crucial for commercial trailer manufacturing, railway infrastructure, and mining equipment assembly.
GO-LOCKBOLT systems are structural lockbolts designed to deliver unparalleled vibration resistance and extreme shear and tensile strengths in heavy-duty connections. Operating as a pin-and-collar system, the installation process relies on cold-forming (swaging) a collar directly into the annular locking grooves of the pin. This unique mechanism generates a permanent, tamper-proof, and uniform clamp load that completely prevents the joint from loosening, even under severe dynamic stresses that would quickly compromise traditional threaded fasteners.
To withstand immense structural loads, GO-LOCKBOLT fasteners are primarily fabricated from high-tensile Steel, Aluminum, and Stainless Steel (including A2 and A4 inferred grades). These materials ensure the fasteners can handle extreme mechanical demands while resisting environmental wear. For enhanced longevity and corrosion protection, the components are commonly supplied with Zinc Plated or Plain finishes, depending on the specific application environment and exposure to corrosive elements.
The GO-LOCKBOLT system is defined by its specialized installation method, which requires a dedicated lockbolt installation tool to actuate the swaged collar into the annular locking grooves. The fasteners comply with rigorous structural standards, notably ASTM F2281, ensuring consistent mechanical performance across critical applications. With grip ranges that vary depending on the pin length, these lockbolts can be tailored to accommodate diverse material thicknesses, providing a customized, very high vibration-resistance solution for heavy-duty joints.
Due to their exceptional strength and immunity to vibration-induced loosening, GO-LOCKBOLT systems are crucial in sectors where joint failure is not an option. They are extensively used in commercial trailer manufacturing, railway infrastructure (such as railcar assembly), and mining equipment. Additionally, they are highly favored in the construction of bridges, heavy commercial vehicles, and large-scale industrial machinery where permanent, maintenance-free structural joints are required.
The GO-LOCKBOLT pin-and-collar system represents the pinnacle of heavy-duty fastening technology. By eliminating the vulnerabilities of threaded nuts and bolts, this swaged fastening solution provides a permanent, vibration-proof connection that ensures long-term structural integrity in the world's most demanding industrial environments.
