Carbon Steel Custom Flange Lock Nut with Anti-Loosening Design

Product Overview

Our Carbon Steel Custom Flange Lock Nut is engineered to deliver unmatched reliability in high-vibration environments. Featuring a built-in flange for load distribution and an anti-loosening mechanism, this nut ensures permanent, secure fastening for critical assemblies in automotive, machinery, construction, and aerospace applications. Crafted from high-grade carbon steel with customizable coatings, it combines durability, precision, and cost-effectiveness.

Key Features

✅ Anti-Loosening Technology

• Nylon Insert or Deformed Threads: Choose between a non-metallic locking insert (prevents loosening via friction) or a distorted thread design for metal-to-metal locking.
• Serrated Flange: Bites into surfaces to resist rotation under dynamic loads.

✅ Flange Design Benefits

• Integrated Washer Function: Eliminates the need for separate washers, reducing assembly time and part count.
• Load Distribution: Reduces surface pressure and prevents damage to soft materials.

✅ High-Strength Carbon Steel

• Grade 8/10.9: Tensile strength up to 1,040 MPa for heavy-duty applications.
• Surface Treatments: Zinc-plated, hot-dip galvanized, or black oxide finishes for corrosion resistance.

✅ Customizable Specifications

• Sizes: M6–M24 (metric) or ¼"–1" (imperial).
• Thread Pitch: Coarse, fine, or custom threads.

✅ Certifications

• ISO 4161 (Prevailing Torque Lock Nuts), ASTM A563, RoHS, and ISO 9001 compliant.
