LEADING TECHNOLOGIES TO SOLVE THE WORLD’S JOINING CHALLENGES
Huck Replaces Welding
Today’s manufacturers have several strong reasons to consider a proven alternative – direct-tension, swaged-on, maintenance-free HuckBolts® from Howmet Fastening Systems. It is safe, simple, fast installation, cost-effective, and has structural integrity.
Huck Outperforms Torque
HuckBolts are applied with direct tension to provide consistent clamp from each fastener. The consistent clamp of direct tension HuckBolts ensure a more secure joint than conventional nuts and bolts.
Huck Saves Time
Often installed in under 2-second. Huck® fasteners are engineered for quick, easy installation, saving valuable assembly time.
Huck Reduces Weight
Huck fasteners offer higher clamp and tensile strength than conventional fasteners, fewer or smaller diameter Huck fasteners can be used. This helps to reduce equipment weight, without loss of performance and fewer inventories are required.
Huck Resists Vibration
HuckBolts are not subjected to the twisting force of torsion that a torque wrench applies to a conventional bolt. So they can safely be taken to higher preload values, resulting in higher clamp, higher strength, and the highest level of vibration resistance of any fastener.
Huck Combats Corrosion
HuckGuard is specifically developed to protect swaged collars and Huck 360® nuts. By combining a zinc-rich basecoat with an organic topcoat, the 2-piece fasteners are protected from metal-weakening corrosives found in the harsh environments.
HEAVY EQUIPMENT

The Huck brand means one thing – reliably strong joints, even in the extreme environments that dozers, excavators, large hydraulically machinery, shredders, and all types of heavy equipment work every day.

FASTENERS FOR HEAVY EQUIPMENT
BOBTAIL®
Delivers up to 5 times the fatigue strength of conventional nuts and bolts Available Sizes: 1/4″, 5/16″, 3/8″, 1/2″, 5/8″, 3/4″, 7/8″, 1″, 12mm, 14mm, 16mm, 20mm Materials: Steel, Aluminum, Stainless Steel Headstyles: Round, Truss, 90° Flush, Flanged, 98T
BOM®
It is the highest strength blind oversize fastener in the world. High strength/diameter ratio: This can be used in demanding structural applications. It is an alternative to threaded fasteners or welding. Very high joint tightness when compared to conventional blind fasteners. BOM is extremely difficult to remove, making it resistant to tampering.
HUCKLOK®
A versatile and hole-filling fastener that can be installed with conventional installation tools. It has a unique circle-lock feature, allowing a simple visual inspection to ensure it is installed properly, 100% of the time. Available Sizes: 3/16″, 1/4″, 3/8″, 1/2″ Materials: Steel, Aluminum, Stainless Steel, 316 Stainless Steel Headstyles: Protruding, Truss, 100° Flush
TRACK AND CROSSING

HuckBolts are unsurpassed for track and crossing applications by combining strong, never-come-loose joining power with easy, safe installation that keeps rail lines open.
