• Secure Fastening with Locking Mechanism: Slotted hex nuts (also called castle nuts) are designed to pair with cotter pins or split pins inserted through the slots, preventing rotation and loosening under vibration. Ideal for critical connections requiring fail-safe retention (e.g., automotive wheel bearings, suspension components).
• Adjustable Preload: Allow precise adjustment of clamping force by aligning the slots with holes in the bolt or stud for pin insertion.
• Safety Assurance: Provide a visible locking mechanism, ensuring compliance with safety standards in high-risk applications.

DIN 935 hexagon nuts with slots, also known as crown-type slotted nuts or round head slotted nuts, are hexagonal nuts with a slotted design. They are used in vehicle assemblies to secure front and rear axles by tightening through axle bolts, ensuring the chassis and tires are firmly connected.

Shape and Structure: These nuts feature a hexagonal head with a slot on one side or the top for locking purposes.

Materials and Coatings: They can be made from materials such as carbon steel, stainless steel, alloy steel, and brass. Surface treatments include blackening, galvanizing, zinc yellow plating, hot-dip galvanizing, phosphating, Dacromet, geomet, martensitic treatment, Rupeter, and Teflon coatings.

Dimensions: Available in thread sizes ranging from M4 to M30, including both coarse and fine threads, with detailed maximum and minimum diameter specifications for different thread sizes.

• High Strength and Durability: Made from high-quality materials, they can withstand significant loads and stresses.
• Corrosion Resistance: Various coatings provide excellent protection against corrosion, ensuring long-term performance in different environments.
• Reliability: The locking mechanism prevents loosening, enhancing the safety and reliability of the assembly.
• Versatility: Suitable for a wide range of applications across different industries.
