It is used for connecting the foundation and the through-pillar in the wooden axis building housing. Although it is used for 2 sets (up and down) set, I think that it is good if there is an integrated one. Since it is construction from the outside, I think that a dub specification is also good.
Fixture is possible without deforming the jig Minimum deviation at the time of retightening can be minimized and work efficiency is improved. In many cases, the screw is tightened above the required torque. Therefore, quenched products + electroless nickel plated work products are available Worry of burning will be alleviated
