■ NOTE
・The MS2.5-M1.6-3.0 has a different shape than the illustration above.
・ Headed inserts are also available.
・ 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 tests before use.
・ Please contact us about the knurling design when knife 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 C).
・ 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.
