1/4 1/2 1/8 Carbon steel Galvanized Blue K Nut Customized Iron Kep nuts SS304 SS316 K NUT

K-nuts, also known as K-caps or flower tooth nuts, feature a special locking structure designed to prevent loosening. These nuts incorporate a movable flower tooth piece pressed into one end through a stamping process, utilizing elastic properties and anti-slip teeth for secure fastening.

• K-shaped profile: Side view reveals the distinctive K-shape that gives these nuts their name
• Internal threading: Compatible with standard screws and bolts
• Dual openings: Semi-circular design facilitates easy installation and removal
• Enhanced locking: Provides superior resistance to vibration and external forces

• Superior vibration resistance through friction-based locking mechanism
• Simplified installation compared to traditional hex nuts
• Reduced thread wear extends fastener lifespan
• Reusable design maintains locking effectiveness

Our K-nuts comply with international standards including:

• ISO 4032/4033: Hexagonal thin nuts (Grades A & B)
• DIN 439: German Industrial Standard for hexagonal thin nuts
• ANSI B18.2.2: American standard for hexagonal thin nuts

K-nuts are ideal for demanding applications requiring vibration resistance:

• Mechanical engineering systems
• Automotive manufacturing
• Construction projects
• Aerospace components
• Industrial equipment assembly

Our galvanizing process applies a protective zinc coating that offers both corrosion resistance and aesthetic appeal. Available finishes include:

• Silver-white (standard galvanized)
• White passivated
• Colored passivated
• Army green passivated
