M8x20mm Slotted Barrel Nuts SHENGQING Cross Dowel Galvanized 20pcs

Description

Product Overview

The M8x20mm slotted barrel nuts offered by SHENGQING represent a precise blend of engineering rigor and practical design, tailored for a wide spectrum of furniture and industrial applications. Each nut is forged from high‑grade carbon steel, a material celebrated for its inherent strength, toughness, and ability to maintain dimensional stability under load. Following the forging process, the nuts undergo a meticulous galvanizing treatment that creates a protective zinc layer, dramatically enhancing resistance to corrosion, rust, and environmental wear. This dual‑stage manufacturing approach ensures that the nuts retain a smooth, burr‑free surface, eliminating the risk of material damage during installation and guaranteeing a seamless interaction with corresponding bolts and dowels.

Dimensionally, the nuts feature a total length of 20mm (0.78 inches), an outer diameter of 11mm (0.43 inches), and a threaded hole diameter of 8mm (0.31 inches). The slotted design provides a clear, linear groove that facilitates easy alignment and insertion of cross dowels, making them especially suitable for panel‑to‑panel connections in modular furniture, office desks, cabinets, and wardrobe systems. The package includes 20 individual nuts, each individually inspected to meet stringent quality standards, ensuring consistency across every unit. The compact packaging dimensions of 3.94 x 2.28 x 0.79 inches and a lightweight 7.41 ounces make storage and handling straightforward for both retailers and end‑users.

Usage

These slotted barrel nuts excel in environments where reliable, repeatable fastening is essential. In residential settings, they are commonly employed to secure the panels of flat‑pack furniture, such as bookshelves, entertainment centers, and bedroom wardrobes, where a clean, hidden joint is desired. In commercial and office contexts, the nuts are integral to the assembly of workstations, conference tables, and modular storage units, providing a sturdy connection that can withstand daily use and occasional re‑configuration. Their corrosion‑resistant finish makes them suitable for semi‑outdoor applications, including garden storage sheds, patio furniture, and equipment that may be exposed to humidity or occasional moisture.

Installation is straightforward: the slotted groove aligns with the cross dowel, allowing the dowel to slide into place while the nut is tightened with a standard hex wrench or screwdriver. The design prevents the nut from rotating independently, ensuring a tight, secure joint without the need for additional locking mechanisms. This simplicity reduces assembly time, minimizes the risk of errors, and enhances overall product durability. For manufacturers, the nuts’ consistent dimensions and high hardness rating support automated assembly lines, improving throughput while maintaining quality.
