[Features] It is a set of 9 semi-long specifications with a total length of 90 mm. The socket hole depth is 50mm, making it suitable for nut work. A shaft press-fit type is used. By using different materials and different hardness for the socket and shaft, the durability is 8 times longer than that of the integrated type (in-house measurement). The socket part is streamlined and designed to reduce resistance when supported by the palm of the hand during temporary tightening. The semi-long size makes it 35% lighter than conventional deep hole sockets. Comes with storage and storage case.
[Use] Houses, building construction, temporary frames, road construction, electrical equipment, water pipes, solar panel construction, air conditioning construction, exteriors, etc.
