In high-vibration industrial, automotive, and machinery applications, maintaining bolt integrity is critical to structural safety and operational reliability. The Anco Lock Nut series addresses this challenge with its advanced self-locking technology, engineered to prevent loosening under extreme dynamic loads. Manufactured by Qiangbang in Wenzhou, China, these nuts combine precision engineering with rigorous quality control to deliver consistent performance where standard fasteners fail. The design eliminates the need for additional lock washers or adhesives, streamlining installation while ensuring long-term joint security.
Available in 304 stainless steel for superior corrosion resistance and 420 stainless steel for enhanced hardness, the Anco Lock Nut offers material versatility for diverse environmental demands. The 304 grade excels in chemical exposure, marine settings, and high-moisture environments, while the 420 variant provides added strength for high-stress mechanical assemblies. Surface treatments include plain, waxed, or galvanized finishes for basic protection, along with black oxide for reduced glare and added corrosion resistance.
The series supports extensive dimensional compatibility, featuring metric sizes (M3, M4, M5, M6, M8, M10) and Unified Thread Standard (8#-32, 10#-24, 10#-32, 1/4″-20, 5/16″-18, 3/8″-16). Anco Lock Nut utilize a hex head design for standardized wrench engagement, with thread lengths adhering to industry standards or customizable per engineering drawings. This cross-protocol sizing ensures seamless integration with existing bolting systems across global supply chains, reducing inventory complexity for maintenance teams.
Unlike conventional lock nuts, the Anco Lock Nut employs a precision-engineered deformation in its upper threads to create radial tension against the bolt. This friction-based locking mechanism activates immediately upon installation, maintaining constant resistance to rotational forces. Rigorous testing confirms consistent performance across temperature fluctuations and cyclical stress, with reuse capability up to five cycles in non-critical applications. The design prioritizes ease of removal with standard tools, avoiding the galling risks associated with nylon inserts.
For assemblies subjected to persistent vibration—such as rotating machinery, transportation systems, or renewable energy infrastructure—the Anco Lock Nut delivers uncompromising security. Its combination of corrosion-resistant stainless steel (304/420), diverse surface treatments, and broad size compatibility establishes it as a versatile, maintenance-free fastening solution. Backed by Qiangbang’s manufacturing expertise and unmarked, ISO-compliant production, these nuts provide OEMs and maintenance engineers with a cost-effective safeguard against catastrophic joint failure.
