■ NOTE
・Pilot hole diameters are for reference only. The diameter should be determined by testing before use.
・Be careful of cracking resin when Catchserts are used for polycarbonate (PC) and other materials which are sensitive to residual stress.
・The diameter of the pilot hole for the object to be mounted should be smaller than the outer diameter of the flange 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.
