Usable for existing places
IDA RING
ida ring IDA RING is wedge type nut locking products. General locking nuts are locked by frictional resistance. But in case of IDA RING, wedge part gets stuck in the spacce between bolt and nut. This stucking holds nut on bolt completely. Also IDA RING can be use for existing places. You don't need remove current nuts. Just set IDA RING to existing places for preventing looseness. ida ring mechanism
Characteristic of IDA Ring
- Easy to fasten and unfasten(less than one rotation)
- Good cost performance
- Usable for existing places
- Material variation
- Color variation
- Big size avairable up to M56(or 2")
- Resusable

Install Inventory
- Train Rail
- Transmission tower
- High Way

How to use
1) Fasten nut normally
2) Insert IDA RING and fasten by hand
3) Fasten IDA RING by wrench
       (1/4 to 1/3 rotation)
Before
without ida ring
After
without ida ring
Specification

- Material : Steel, SUS304,
*) Other size can be acceptable



High performance locking nut
SUPER SLIT NUT (patent pending)
locking nut SUPER SLIT NUT has spring function on the upper part which generate prevailing torque. This spring parts hold SUPER SLIT NUT on bolt by elastic deformation when you screw up. SUPER SLIT NUT exerts stable locking effect by simple structure.
Characteristic of SUPER SLIT NUT
- Clear one milion times vibration test!(more than NAS3350)
- Reusable (*)except for hot dip galvanizing plating
- Don't drop even fastening insufficiency
- Locking by only this nut ->improvement of operational efficiency
- Almost never damaged on bolts and stable axial tension

locking nut
USAGE
- For bridges, High ways , Steel towers
- For train rail, Train car
- Around engine or trans mission of vehicles
- Around engine of vessels and air planes
Specification
