Ensuring the long-term integrity and safety of bolted joints demands reliable fastening solutions. The Anco Lock Nut stands out as a superior choice, specifically engineered as a high-performance flange lock nut crafted from durable stainless steel. Designed to DIN6923 standards, this hex K-lock kep nut integrates a wide flange that functions as a built-in washer, distributing clamping pressure effectively and significantly enhancing vibration resistance. This makes the Anco Lock Nut an essential component for critical applications where security is paramount.
Manufactured from high-quality stainless steel, the Anco Lock Nut is available in grades 201, 304, and 316 to suit diverse environmental and strength requirements. Grade 304 offers excellent general corrosion resistance, while Grade 316 provides superior protection against chlorides and harsh chemicals, ideal for marine or industrial settings. Grade 201 offers a cost-effective solution for less demanding environments.
The defining feature of this fastener is its integrated flange. Unlike standard hex nuts requiring a separate washer, the flange base on the Anco Lock Nut significantly increases the bearing surface area. This design effectively distributes the clamping force over a wider area, minimizing the risk of surface damage to softer materials, preventing embedding, and compensating for minor irregularities in the mating surface. Crucially, this contributes significantly to the nut’s exceptional resistance to loosening under vibration and dynamic loads. The nut is precision-formed into a hexagonal shape, conforming strictly to the DIN6923 standard for consistent quality and interchangeability.
To further enhance performance and meet specific application needs, the Anco Lock Nut is offered with selectable surface treatments. A standard plain finish provides a clean, uncoated stainless steel surface. For improved corrosion resistance, particularly for Grade 304 and 316 nuts, a passivation treatment is available, removing free iron particles and forming a protective chromium oxide layer. Alternatively, a waxed coating can be applied to facilitate smoother installation, reduce thread galling, and provide a temporary barrier against corrosion during storage and initial service.
Available in a comprehensive range of thread sizes (M3, M4, M5, M6, M8, M10, M12), the Anco Lock Nut delivers both exceptional locking security and operational efficiency. Its DIN6923 compliant hex flange design eliminates the need for separate washers, simplifying assembly and reducing inventory requirements. Combined with the corrosion resistance of stainless steel (201/304/316) and optional surface treatments (Plain, Waxed, Passivated), this nut guarantees reliable, long-lasting fastening.
