Founded in USA, HUCK is the originator of global structural lockbolts with exclusive ring groove locking patent. The mandrel is permanently locked after riveting without falling off, delivering ultra-high shear resistance and vibration fatigue performance to eliminate loose failure of ordinary pop rivets under long-term vibration. It is the mandatory imported rivet brand for high-speed rail carriages, shipping containers, heavy construction vehicles and bus body export projects. Fastener_hk stocks full genuine HUCK lockbolt series in Hong Kong warehouse.
| Performance Item | Genuine American HUCK Structural Lockbolt | Domestic Standard Ring Groove Structural Rivet |
| Locking Mechanism | Permanent mandrel lock via ring groove plastic extrusion, zero separation risk | Simple claw snap lock, claws fatigue and open after high-frequency vibration |
| Min Single Shear Force (M6 Size) | ≥18500N | ≥12200N, 34% lower load capacity than original brand |
| Min Single Tensile Force (M6 Size) | ≥26800N | ≥17600N, huge gap in ultimate load bearing |
| Alternating Vibration Fatigue Life | 1,000,000 cycles without loosening or fracture | Obvious preload attenuation after 300,000 cycles |
| Applicable Sheet Thickness Range | Single rivet covers 3-8mm combined sheets for multi-thickness mixed panels | Only fit 2-4mm thin plates, incomplete locking for thick sheet riveting |
| Overseas Engineering Recognition | Inspection-exempt approved brand for European & American rail and container projects | Only allowed for small inland equipment, not accepted by high-end export projects |
1. Sheet thickness matching rule: Follow original specification sheet strictly, total stacked plate thickness cannot exceed rivet adapt range to avoid incomplete mandrel locking; 2. Mandatory tool matching: Original Huck pneumatic riveting gun must be adopted; domestic guns deliver unstable pulling force leading to failed ring groove lock and loose rivets under vibration later; 3. Graded material selection: Carbon steel Huck rivets for indoor dry containers & carriages, SUS A4 316 stainless steel version for coastal shipping containers & offshore construction machinery; 4. Anti-corrosion matching tip: Spray weather-resistant sealing coating on rivet heads after riveting for marine export equipment to block seawater chloride erosion.
1. Genuine identification: Each Huck rivet head carries exclusive brand LOGO & size code, counterfeits have blurry marking and uneven ring groove depth; 2. Customs declaration rule: Truthfully declare overseas original brand Huck, provide US original agency authorization to avoid detention during IP inspection; 3. Audit document matching: Original mechanical tensile test report, ASTM material certificate and RoHS environmental certificate attached per batch; 4. Replacement ban: Domestic structural rivets cannot substitute if export drawings specify Huck lockbolts, European & American supervisors will reject full container goods once tensile sampling test fails on site.
