Description

■ 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: Stainless steel

Most representative stainless steel (equivalent to SUS304)
The strength is almost equal to "iron".
Excellent corrosion resistance and good mechanical properties.
Although it is normally not magnetic, it can harden due to cold processing, and it may cause magnetism.
■Surface treatment: fabric

Surface treatment/plating is untreated.
Therefore, corrosion resistance and appearance are the characteristics and color of the material itself.
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.
