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
- 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
