Product Description

The T-shaped plum blossom groove has a symmetrical arc-shaped groove wall, a flat groove bottom without any depressions, and a precise ratio of groove depth to groove width to ensure that the plum blossom wrench is fully inserted and prevent slipping. The edge of the groove is passivated to avoid wear or cracking of the groove after long-term use. The thread profile is full and the pitch is uniform, and it is formed using precision rolling technology.
