■ Shape: Hex Low Nut (2-piece set)
Hex nut for loosening and tightening using two convex and recessed nuts. The convex nut has a shape that promotes wobble action. When tightening with concave nuts, friction on the screws such as bolts and other parts of the screw to create a loosening effect.
Lower than regular 2 pair locking hex nuts.
Use a tool such as a spanner or wrench to tighten it.

■ Thread Shape: Coarse
It is the most standard pitch in Japan as prescribed by ISO (International Organization for Standardization) standard. The most frequent distribution in Japan.

■Material: Iron
"Iron" is "steel" and is an alloy of iron containing carbon.
Although it is commonly used in many circulations, it is cheap materials, but due to the downside of it is easy to rust, many surface treatments will reduce corrosion.

■Surface treatment: Trivalent white
It has the same corrosion resistance as "chromate" and has the same possibility of imitation self-healing.
Unlike hexavalent chrome, it is non-toxic and compliant with RoHS directive. So it is used as an alternative to unichromate/chromate.
Color is "Silver Color".

Product Features:
Shape
Use 2 pieces of upper nut (convex type) and lower nut (concave type).
The upper nut is round to the bolt, but the lower nut is to the center of the bolt.
It has been polarized to prevent slippage.

Features
The lower nut has a polarized core, so the lateral force is applied when tightening the upper nut.
The friction on this male thread creates a loosening effect.
Can be hand tightened to the desired position.
Can be used repeatedly.
HLB is for bearings.
