BESTTOOL KOSEI drop prevention socket 21mm

Socket for 18V compatible electric/rechargeable impact driver with a mechanism that prevents the socket from falling even if the bit breaks. If a load is applied to the bit due to overtorque, it will always break inside the socket, so it will not drop (PAT.). Since there is no need to worry about the socket falling, you can safely work at heights. Since the bit always breaks inside the socket, the broken bit does not get stuck in the impact body and is easy to remove and replace. Since the inner diameter is dodecagonal, it is easy to enter the nut quickly and the work efficiency is very good.

For tightening and loosening bolts and nuts using an electric screwdriver during work at height.
