LocTec®

Screw fastening with safety drive

An ARNOLD fastener with the LocTec® locking drive cannot be removed by conventional means. Therefore no need for additional security devices. This means that there's no need for secondary steps to hammer in a steel ball or use shear-off fasteners.

Benefits

By using LocTec® you can reduce assembly costs, keep stocks to a minimum and drastically cut the costs for your lock fasteners. The reliable protection against loosening ensures that there is no risk even if the LocTec® safety screwdriver bit should fall into the wrong hands.

Characteristics

The ARNOLD LocTec® screw is simply inserted using the LocTec® safely bit and then tightened. A secure fastening is formed. The LocTec®'s special flank geometry screw ensures that attempts to undo it (even with the LocTec® safety bit) will always result in the tool slipping out.

Advantages

In addition to creating protection against every conventional attempt to unscrew the fastening, LocTec® provides the extra advantages of a high-quality screw:

  • Accurate transmission of defined torques
  • No waste scrap as would be caused by shear-off screws
  • No additional work steps (such as would be needed for drilling or bonding)
  • No danger that the end product will be damaged (such as can happen when a ball is hammered in)
  • Same process speed as for other screw fasteners
  • Automatic assembly possible due to precise bit guidance
  • No corrosion effects
