Titanium NAS Shear-Type Lockbolts

Titanium NAS lockbolts are designed for use in high-strength lightweight applications. The lockbolt is readily adaptable to high volume production methods. 

During installation, the collar is swaged into the lock grooves of the pin and forms a high-strength, vibration-resistant joint.  The simple installation procedure reduces production time to a minimum, resulting in lower production costs. 

The stump-type lockbolt fasteners are specifically designed for use with automated equipment. Automated systems install fasteners at a rate up to 10 times faster than hand-installed threaded fasteners.
