High-strength, vibration-resistant, and eco-friendly, the NeoBolt non-breakstem steel lockbolt fastening system is designed for use in heavy-duty structural applications. This unique two-piece fastener design features annular locking grooves and shockless installation.

Unlike traditional lockbolt fasteners, there is no pin break so there is no metal waste, reduced noise, no installation shock, no risk of pintails being dropped into the application or work area, and no corrosion at a pin break surface. With no shock loads, tool life is extended and operator fatigue is reduced.

NeoBolt creates a maintenance-free hold, with no torque or re-torque required.

Assembly applications where NeoBolt fasteners are found include railway, truck & trailer, commercial vehicles, solar & wind energy, bridge building, mining equipment, screening equipment, fencing and security screens, construction, overland infrastructure, and power and utility services.

Available in many fastener diameters and lengths, NeoBolt lockbolts can be placed with a range of installation tools featuring fastener-specific nose assemblies.
