【Cautions for using electrical products】
When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions.
Since the plug type is Japan type(A or B type), please check the voltage and use a transformer.
Please note that a transformer is different from a conversion adapter.
We are not responsible for malfunctions caused by use without a transformer.
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[Product specifications] ●Product name: Hexagonal lock nut ●Material: 403 stainless steel ●Magnetic classification: weak magnetic ●Color: Silver ●Package contents: 50 pcs x hexagonal lock nuts ●Thread diameter: M4 ●Height: 4mm ●Hexagonal width (across width): 6.8mm.
High Cost Performance: Made from 304 stainless steel, it offers high hardness, corrosion resistance, and durability for long-term use. It can be widely used in automobiles, construction machinery, shipbuilding, and other applications. It eliminates the need for double nuts, castle nuts, or special washers, reducing total assembly costs.
[Excellent Locking Effect] The inner diameter of the nylon ring is designed to match the effective diameter of the nut thread. When mated with the male thread of the bolt, a female thread is formed in the nylon ring, creating mating friction. This friction creates torque, providing excellent locking effect. Prevents the nut from loosening due to rotational vibration, linear vibration, and impact.
[High heat and friction resistance] The nylon ring that acts as the locking mechanism is highly heat and friction resistant. It can be used in temperatures between -40°C and 120°C.
[Does not damage the mating material] The anti-loosening mechanism is made of nylon, so the tightening torque is stable and it will not noticeably damage the mating bolt like other metal anti-loosening nuts.
1. Nylon insert lock nuts, polymer insert lock nuts, or elastic lock nuts are a type of lock nut. 2. They have a nylon collar insert that is resistant to rotation. 3. The plastic insert is located at the end of the nut, and its inner diameter (ID) is slightly smaller than the outer diameter of the screw. 4. The insert elastically deforms onto the screw threads, but the threads do not bite into the nylon.
