Usage Example
· By using a flat head bolt, you can mount or fix it to another component.
Product Feature Details
· All countersunk bolts in the set product are made of stainless steel and can be used without being affected by magnetic force. Also, since they have a hex socket head, a hex wrench that matches the width across flats of the hex socket is required.

Magnetization Direction: Y-direction
Cautions and Prohibitions
- There is a risk of injury, such as fingers getting pinched, if the magnet adheres to each other, tools, or iron pieces.
- If the magnets are accidentally attracted, fix one magnet and move the other to the side. This method makes it relatively easy to remove.
At this time, if tools are used, the magnet may be cracked or chipped. - Magnets are generally fragile, and neodymium magnets tend to corrode from the damaged surface.
Also, there is a risk of injury from these fragments. - Keep magnets out of reach of children. If you accidentally swallow a magnet, contact your doctor immediately.
- People with metal allergies may experience itching or redness if they come into contact with magnets.
If you experience any of these symptoms, do not touch the magnet. - If the magnet comes into direct contact with water, its components may leach out. Never drink this water.
- Bringing a magnet close to a credit card, cash card, etc., may render it unusable.
- Bringing magnets close to precision equipment such as computers, smartphones, watches, etc., may cause malfunction.
- Placing a magnet close to an electronic medical device such as a cardiac pacemaker may impair its normal operation.
- Demagnetization may occur if the magnet is used outside the operating temperature range.
- Applying a strong impact to the magnet or processing it may demagnetize it.
- Excessive bending of rubber magnets with a thickness of 2 mm or more may cause cracks.
