Why Choose 12-Point Fasteners?

The 12-point design offers superior torque application, faster installation, and reduced slippage compared to traditional hex heads—ideal for high-torque and confined-space applications.

⚙️

Higher Torque Capacity

12 points allow for more contact angles, enabling higher torque without rounding the head—critical in industrial and automotive applications.

⚡

Faster Installation

With twice as many engagement points, tools can connect every 30°, reducing rotation needed and speeding up assembly lines.

🔧

Reduced Slippage

More contact points mean less chance of tool slippage, improving safety and reducing damage to fastener heads.

Flange Bolt Technology

Flanged headed nuts and bolts are engineered to eliminate the deficiencies found with traditional washers. The integrated flange distributes load evenly, prevents loosening, and reduces assembly time.

  • ✓ Integrated washer eliminates need for separate washers
  • ✓ Even load distribution reduces surface damage
  • ✓ Improved vibration resistance and anti-loosening
  • ✓ Reduced assembly time and part count
