Characteristics
- Two-hole flat head machine screws.
- With nylon patch.
- The friction of the nylon adhered to the thread suppresses the return rotation of the thread.
- Even if the tightening force is lost, the return rotation is suppressed, preventing the screws from falling off.
- The heat resistant temperature of the nylon patch is 120°C.
- This prevents mounting and removing with regular tools.
- Install and remove with SRTB Dedicated Bits and SRD Dedicated Magnetic Screwdriver together.
- The simple head design is also suitable for decoration.
