The primary reason for bolts breaking is a drop from the initial tightening strength (axial force) of the screw, leading to a shortened life span and metal fatigue/breakage. That is to say that a low-cycle fatigue of the bolt is induced, which leads to failure. There are many products in the world that can prevent screws from falling out, but none that prevent them from becoming loose. At the time, there were no self-locking components that could prevent loss in the axial force. We then focused on the idea of completely eliminating play in screws. Our initial manufacturing concept was a single lock nut that could be produced as inexpensively as possible. No matter how much we brainstormed, however, our assumptions and preconceptions blocked us from thinking outside the envelope because of our initial conditions and focus on the preventing screws from coming out.

Products

HLN

HARDLOCK NUT

  • Self-locking effect recognized by the world: HARDLOCK Nut also passed the United States NAS (National Aerospace Standard) aviation standards.
  • Enables Torque and Axial Force control: Controlling axial force with proper torque wherever it is used.
  • Possible to re-use: All metal with little abrasion, sustains a high self-locking effect.
  • Good and simple workability: Easy installation with commercially available tools.
  • Provides substantial cost savings: Allows significant reduction in total cost by reducing maintenance costs, labor costs etc.
HLB

HARDLOCK BEARING NUT

  • Very high self-locking effect: Just like the HARDLOCK Nut, no matter the conditions the self-locking effect remains secure.
  • Enables Torque and Axial Force control: Can be completely locked in the middle of the shaft, adjustable positioning is also possible.
  • Possible to re-use: All metal with little abrasion, sustains a high self-locking effect.
  • Good and simple workability: Easy installation with commercially available tools.
  • Provides economic benefits: No other self-locking components such as washers etc., no key processing is required.
HLS

HARDLOCK SET SCREW

  • Very high self-locking effect: Just like the HARDLOCK Nut, no matter the conditions the self-locking effect remains secure.

  • Possible to re-use: All metal with little abrasion, sustains a high self-locking effect.

  • Good and simple workability: Easy installation with commercially available tools.

  • Provides economic benefits: No retorquing work, no additional self-locking components such as adhesives etc. are required. The HLS provides significant cost reduction and superior self-locking effect.
