■ NOTE
  • Number of knurling: one on the SG3.6-M2-2.2
  • Please contact us if you need Pb-free material for environmental reasons.
  • Pilot hole diameters are for reference only.
  • The diameter should be determined by testing before use.
  • Please contact us about the knurling design when SG Locks are used for polycarbonate (PC) and other materials which are sensitive to residual stress.
  • The diameter of the pilot hole for the mounting object should be smaller than the outer diameter of the insert (Dimension A).
  • When inserts are tightened by screws, choose the screw length so that screws do not reach the bottom of insert pilot holes.
  • The specifications are subject to change without notice.
  • Please contact us if you have any other questions.
