■ NOTE
・ 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 D).
・ 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.
