▩ 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)

▩ Applications
