Alloy Steel (8740) NAS Shear-Type Lockbolts
Alloy steel NAS lockbolt fasteners are designed for use in high-strength 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.
