Alcoa’s Huck 360TM Fastener Successfully Completes 20,000-Mile Test

WASHINGTON--Alcoa (NYSE:AA) announced today that its Huck 360TM fastener successfully completed a rigorous 20,000-mile durability test.

The fastener, which attaches the front and rear spring suspension brackets on a vehicle’s frame, was tested by AM General LLC using standard military durability testing procedures, which are far more rigorous than testing for commercial vehicles.

AM General drove their vehicle on a test track for 600 miles per week until the vehicle reached 20,000 miles without any loosening of the fasteners or signs of wear.

“This is a tremendous accomplishment for our latest fastener, the Huck 360,” said David Dobson, president, Alcoa Defense. “We are thrilled that AM General has selected it for testing. It is an extremely demanding application that is perfect for showcasing the long-term durability of the Huck 360.”

Requiring only a standard wrench or socket for installation and removal, the Huck 360 provides a convenient fastening solution for vehicle applications. Ensuring excellent long-term vibration resistance and durability, the Huck 360 offers a higher clamp load and five times the fatigue strength of conventional lock nuts and bolting systems. Additionally, the Huck 360 eliminates the need for special tooling and patches, adhesives or lock washers to prevent loosening.

“After considering several Alcoa proprietary fastening technologies, the Huck 360 was selected for testing because it can be easily removed and replaced in the field,” said Alcoa Fastening Systems Sales Program Manager Brian Mondello.

Following successful completion of the 20,000-mile test, the fasteners are currently undergoing additional testing to determine how long the Huck 360 fastener can be used before it reaches the end of its service life.

AUSA Annual Meeting attendees can learn more about the Huck 360 by visiting Alcoa Defense at booth 4131.
