Prevention of damage to screw heads and reliable tightening


  • Hexalobular socket shapes*1 are designed to withstand high tightening torque compared to cross-recesses. ⇒Features of the Hexalobular Socket
  • Screw heads are unlikely to be damaged due to tightening, allowing safe and secure tightening to be performed.
  • Mounting/removing with regular tools such as hex keys and screwdrivers is not possible. Also usable for applications including prevention of disassembly, theft, or tampering for devices or facilities.* 2
  • Install and remove with SKX Dedicated Wrench or SKXB Dedicated Bit and SRD Dedicated Magnetic Screwdriver together.
  • Use the SKX-N hexalobular wrench for extremely limited access spaces for mounting and removing in tight spaces.

*1: The hexalobular shape is prescribed by JIS B 1015: 2008(ISO 10664: 2005)"Hexalobular internal driving feature for bolts and screws".
*2: Tools for hexalobular sockets are commercially available. When tampering prevention is the main objective, consider tamper resistant screws. ⇒Tamper Resistance Screws
