Quality Lock (Mold-in Inserts）
This is a revolutionary type of insert nut with a square groove in the middle.Compared with conventional inserts with diamond knurling, the strength is significantly increased.
No cutting dust is generated, thus improving the quality.

■ NOTE
・ Headed inserts are also available.
・ Please contact us if you need Pb-free material for environmental reasons.
・ Choose the die pin diameter based on the dimension of the hole size before threading.
・ The diameter of the pilot hole for the mounting object should be smaller
than the outer diameter of the insert (Dimension A) if possible.
・ 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.
