Product Details
These DIN6334 long hex nuts are engineered as coupling devices with internal threads at both ends, facilitating the connection of threaded rods for adjustable length extensions. The white zinc plating creates a smooth, aesthetic barrier against oxidation, suitable for visible installations, while blue zinc provides a tinted, more robust shield for variable conditions. Constructed from carbon steel or stainless steel, they support thread pitches from 1mm to 4mm, ensuring compatibility with standard rods. Duojia’s precise threading and galvanization processes guarantee uniform coating and strength, certified by SGS for reliability. Installation is simple: thread onto rods and tighten with a hex wrench, applying even pressure to avoid stripping—perfect for scenarios requiring frequent adjustments without compromising hold. Regular inspections of the zinc layer are recommended; repair any damage with anti-rust agents to maintain protection. These nuts excel in automotive chassis, construction scaffolding, and heavy equipment, where their elongated design handles high loads. Available in sizes M6 to M36, with minimum orders of 100 pieces and 14-30 day delivery in secure cartons or pallets, they are exported worldwide, delivering versatile, corrosion-protected fastening for industrial extensions.

Product Features
DIN6334 Long Hex Nuts with white/blue zinc plating stand out for their extended cylindrical form, enabling seamless rod coupling with even torque distribution to prevent bending or failure under load. The galvanization process ensures a durable zinc shield, with white offering a polished, non-reflective surface for clean environments and blue providing superior anti-corrosion for exposed uses. Available in carbon steel for strength or stainless for added resistance, they feature precise internal threading that grips rods securely without slippage. Their hexagonal exterior allows easy wrenching in tight spaces, and the design supports high-tensile applications without deformation. Duojia’s customizable options include length variations, all tested for coating adhesion and mechanical integrity. These nuts resist environmental wear, maintaining performance in humid or industrial settings, and require minimal maintenance beyond periodic checks. Lightweight yet high-capacity, they optimize assemblies by reducing parts count. Eco-friendly production minimizes impact, aligning with ISO standards. This blend of attributes delivers reliable extension, corrosion defense, and ease, making them ideal for scenarios needing stable, adjustable connections with long-term reliability.
Product Applications
These White/Blue Zinc DIN935 Slotted Castle Nuts find extensive use in environments requiring secure, adjustable fastening with anti-loosening capabilities. In heavy industry, they connect machinery components and gears, integrated with cotter pins to counter vibrations in engines or conveyors. Automotive applications include securing axles and suspensions, where the zinc plating protects against road debris and moisture for prolonged safety. General equipment assembly benefits from their role in adjustable fixtures, allowing easy realignment without compromising hold. Outdoor and construction settings utilize blue zinc for weather-exposed joints in scaffolding or frames, ensuring rust-free performance. In manufacturing, white zinc variants provide a clean finish for visible machinery parts. Duojia’s products, shipped globally, accommodate custom needs in agricultural tools or robotics, with pin-locking simplifying maintenance. Their design supports repeated use, enhancing efficiency by preventing failures and reducing retightening needs in dynamic systems. Versatile for both professional and field repairs, they improve reliability across industries, from automotive to industrial setups.
