In 2015, STANLEY® Engineered Fastening, the largest blind-rivet supplier in the industry, introduced Avdel® NeoBolt®, a non-breakstem lockbolt fastening system for heavy-duty structural applications.  The two-piece NeoBolt® fastener features a collar and a pin with fine-pitch locking grooves that, when installed, provides unmatched vibration resistance and fatigue performance.

Unlike traditional lockbolt fasteners, there is no pin break so there is reduced noise, no metal waste, 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.

Designed for industries ranging from rail, truck, and trailer to mining, construction, commercial vehicles, and alternative energy applications, NeoBolt® fasteners can withstand the stresses of the toughest applications and environments.

NeoBolt® fasteners are quickly and easily installed in seconds to provide a secure, maintenance-free, long-lasting joint compared to traditional nut and bolt assemblies. NeoBolt® offers a permanent joint with far greater vibration resistance that avoids loosening by unscrewing.

To install the NeoBolt® fastener, the pin is placed through the materials to be joined and the collar screwed onto the pin thread with just a single turn. This collar “fit-up” feature enables easy pre-assembly in joints and avoids the need to support the pin during the subsequent swaging operation. A tool with an open collet is placed over the pin tail end, and when actuated, the collet closes and pulls the pin.  The anvil moves onto the collar, closes any joint gaps, and swages the collar wall down into the pin locking grooves. Once full swaging load is reached, the tool travel stops and returns to release the pin.

Radial bars on the collar flange, standard on all sizes, further enable quick visual verification of full swage during installation or inspection.

NeoBolt® lockbolts are available in a variety of sizes ranging from 3/16” to 1” (4.8mm to 25.4mm) diameter, with a grip range from 0.520” to 6.23” (1.3 to 158mm).

The NeoBolt® lockbolt is the newest product in the Avdel® family of structural lockbolt systems which includes Avdelok®, Avdelok® XT, Maxlok®, Avtainer®, and Avbolt®. Lockbolts provide consistent high clamp, shear, and tensile strength as well as excellent vibration resistance, multi-grip capability, and high-speed assembly.
