WORLD APPROVED LOOSE REDUCTION EFFECT: Cleared with plenty of room to the National Aerospace Standard aircraft standard.
Torque and Axis Management: Achieves axial strength management with appropriate torque that fits the location of use.
Repeated:Made of all metal with less wear points and long lasting slacking effect.
Easy to work: Tighten with just one tool on the market.
It has a loosening mechanism using the principle of ancient Japanese "wedge. In order to utilize the structure, there are two convex nuts (1) which have been polarized to the boss portion, and (2) concave nuts with a deep circular processing, which creates a strong locking effect due to the principle of wedge. This allows the HLN Hard Lock Nut to be a powerful loosening effect that integrates the bolts and nuts.
HLN Hard Lock Nuts are strongly locked to repel any impulse or impact.
When tightening recessed nuts, the tightening tool does not stick to convex nuts.
