The advantages:
Easy press-in insertion
High torque resistance
Low bursting stress allows the use of thinner wall bosses
reducing the risk of sink marks
Self-aligning-Assists Installation
Designed for thermoplastic plastics（ABS,PP,etc.）
Installation instruction:
The insert must be installed using a squeeze action press,NEVER a hammer blow.
The insert must be allowed to rotate in the direction of the knurl during installation.
This is best achieved by the use of a punch having either a polished face or a thrust bearing.
The insert must be kept axially square during installation,as any tilting will induce side loads on the boss wall.
The recommended hole size must not be increase beyond the top tolerance limit since oversize holes reduce or remove the self aligning effects,producing side loads and consequent risk of boss cracking.
