Product Information

▩ What is V-LOCK?

  • V-LOCK is a screw thread system with a perfect anti-loosening function. When fasteners are joined together with a specially threaded fastener, which has the V-LOCK screw thread on one of the bolt and nut, the loosening of bolts and nuts during vibration and impact is prevent.

 

▩ Principle of V-LOCK

  • The screw thread of V-LOCK consists of two tangeltial parts (the first and second tangential parts) to induce double dontact point locking with the other object with a common screw thread. It maximizes the friction force between the bolt and nut screw threads through double contact points and performs an anti-loosening function.

 


 

▩ Technology of V-LOCK    

  • Anti-loosening fuction when it is joined with fastener with a common screw thread (V-LOCK bolt & common nut / V-LOCK nut & common bolt)
  • Passed the maximum vibration test (NASA standard ; NAS 3350)
  • Completed the anti-loosening function test that measures the change in axial force (Junker Test ; DIN 65151)
  • Obtained the world's first DNV·GL classification certification for fasteners
  • Daekwang Metal's patented technology
  • Low unit price (same manufacturing process as the common bolts and nuts excluding the dies, tap and bite the form the V-LOCK screw thead)
  • Wide range of applications (applicable regardless of the shape, material and plating of products)

 

 

▩ Effect of V-LOCK    

  • Perfect anti-loosening effect during extreme vibration and impact
  • Modifies the screw thread of the common bolt and nut specification ⇒ Alternative for existing products)
  • Component parts, such as washers, double fastening, coating processes, screw adhesive, and others ar not required. ⇒ Cost reduction due to the single fastening of the bolt and nut
  • Same torque as the fastening and loosening of common bolts and nuts ⇒ Increases work efficiency

 

▩ Applications 

  • Components which maintenance is difficult
  • Component used under extreme vibration
  • Widely applicable in all industry


▩ Breakaway view 


 

 

 

  • Product Specification : M6 ~ M20(current productive capacity) / M6~M42
  • Material : S45C, SUS, SCM, Plastic(Injection), EP, etc.
  • Plating : Applicable to most plating including hot dip galvanizing
  • Customized products is also suppliable
