Thank you for your continued trust and support of HARDLOCK products.

Recently, an increasing number of imitation HARDLOCK Nuts (HLB)—low-cost counterfeit products—have been found circulating on major e-commerce platforms both domestically and internationally. As a result, we have received numerous inquiries and complaints regarding quality issues from customers who unknowingly purchased these imitation items.

These counterfeit products differ significantly from genuine HARDLOCK products in both specifications and performance, and more critically, they do not meet our safety standards. We are extremely concerned that the use of such counterfeit items could lead to product failures and pose a serious risk to your operations.

We are taking all necessary measures to address the issue, but we strongly urge customers to carefully verify their purchases to ensure they are acquiring authentic HARDLOCK products.
*Please note: We cannot be held responsible for any malfunctions, accidents, or damages caused by the use of counterfeit products.

If you have any questions or uncertainties regarding product authenticity, please do not hesitate to contact us directly.

HARDLOCK products are the result of over 40 years of innovation and safety-focused engineering—a true embodiment of intelligent fastening design.

While the original patents may have expired, we continue to evolve our products by listening to the needs of our global customers and addressing emerging challenges. Through this ongoing development, we have secured:

• 19 active patents
• 10 registered designs
• 20 registered trademarks
  (As of January 2023)

Some counterfeit products may look identical externally but lack the advanced internal structure and improvements developed through decades of R&D. These improvements are backed by new patents and extensive in-field performance testing.

We will continue to lead the industry in developing fasteners that deliver unmatched safety and reliability.

However, products that simply imitate the external appearance of HARDLOCK Nuts cannot guarantee safety or performance. Safety is not something that can be replicated overnight.

For your protection and peace of mind, we strongly recommend using only authentic HARDLOCK products marked with the “HARDLOCK” engraving.
