Double Ended Screws are self-tapping wood threads at one end, which can be directly locked into the soft material (wood). The other end is a mechanical thread, which can be locked with the nut. Because of its simple installation, good concealment, and high strength, it is very popular with customers.
Note:
1. Choose the size, flat position, and style according to the needs of installation at the time of purchase. There are some errors due to manual measurement, but it will not affect its use.
2. The mechanical threaded end (flat end) cannot use with a hammer, as it will make the thread and become unusable.
