Product Details
Engineered with castellated slots on top, the White/Blue Zinc DIN935 Slotted Castle Nuts allow seamless alignment with bolt holes for cotter pin insertion, creating a mechanical lock against loosening from torque or shakes. The zinc plating forms a thin, adherent layer that shields the carbon steel core from rust, with white offering a polished look for visible installations and blue adding a tinted, enhanced barrier for better environmental tolerance. Stainless steel variants extend usability in corrosive areas, while thread pitches accommodate precise bolting needs across sizes M5 to M36. Duojia’s advanced tapping and plating processes ensure even coverage and strength, verified by SGS certification. Installation requires torquing the nut, aligning a slot with the bolt’s pin hole, inserting the cotter pin, and bending its ends—no special tools beyond a wrench are needed, making them user-friendly for field adjustments. For environments, white zinc suits dry indoor use, blue for moderate exposure; inspect plating regularly and repair scratches with zinc-rich paint to sustain protection. These nuts support automotive suspensions, gear systems, and equipment frames, with minimum orders of 100 pieces and 14-30 day delivery in secure packaging. Exported to diverse markets, they offer versatile, anti-vibration fastening that streamlines assembly and boosts longevity in demanding applications.

Product Features
These White/Blue Zinc DIN935 Slotted Castle Nuts incorporate a unique castellated structure with slots that facilitate cotter pin locking, offering unmatched resistance to vibrational loosening compared to standard nuts. The zinc plating enhances corrosion defense, with white providing a sleek, bright surface for aesthetic integrations and blue delivering advanced passivation for extended life in variable conditions. Constructed from carbon steel or stainless steel, they boast high tensile strength across grades, ensuring dependable performance under stress. Versatile threading options allow for tailored fits, and the design supports easy disassembly for maintenance without thread damage. Duojia’s customizable features include plating variations, all rigorously tested for adhesion and torque tolerance. These nuts excel in preventing back-off in dynamic systems, with the plating resisting chipping and maintaining visual appeal. Lightweight yet sturdy, they minimize assembly weight while maximizing security, ideal for adjustable setups. Environmentally conscious production adheres to ISO standards, reducing waste. This array of attributes ensures vibration-proof reliability, corrosion protection, and user convenience, positioning them as an optimal choice for applications demanding secure, long-lasting fastening with minimal upkeep.
Product Applications
White/Blue Zinc DIN935 Slotted Castle Nuts are tailored for anti-loosening in high-vibration scenarios across multiple sectors. In automotive industries, they lock axles and steering components, integrated with cotter pins to withstand road stresses and ensure vehicle safety. Heavy machinery benefits from their use in rotating assemblies and gears, where the slotted design prevents failures during operation. Outdoor and industrial equipment, such as conveyor systems or agricultural tools, utilizes the zinc plating for weather resistance in exposed conditions. General engineering applies them in structural bolting, offering adjustable security without frequent retightening. In marine or mildly corrosive settings, blue zinc variants provide added protection for fittings and mounts. Duojia’s exported products support custom installations in construction frames and equipment, with straightforward pin-locking simplifying field repairs. Their adaptability reduces downtime, enhancing efficiency in both professional and maintenance tasks, from DIY adjustments to large-scale manufacturing, ensuring stable performance worldwide.
