＊The hexalobular shape is prescribed by JIS B 1015：2008（ISO 10664：2005）“Hexalobular internal driving feature for bolts and screws”.
Application
Fixing workpieces and jigs and fine positional adjustment of heavy objects
Characteristics
- When the screw is tightened, the workpiece is strongly clamped by the head, which is decentered from the shaft center of the screw. The wedge effect creates a large clamping force with low tightening torque.
- The screw has a hexalobular socket＊ that can withstand high tightening torque.
- Install and remove by using SKX Special Key.
- SLEC-B-EL is electroless nickel（EN）plating type. It is intended for applications that require corrosion resistance.
- Since the precision-processed guide receives the clamping load, durability during clamping is increased.
Usage example
Fixing Workpiece and Jigs
