Tappex M4 x 0.5 Thread Insert 002M4-40

Multisert unheaded thread insert is for use in thermoplastics where the mating component sits flush. The plain top ring provides a good bearing surface. It should be specified for use in flexible materials which allow cold press fit insertion, for optimum production rates. For improved performance, it can be press fitted with heat or ultrasonic, when the fill of molten plastic around the barb form is maximised. Press fitting into harder or flame retardant materials requires heat or ultrasonic assistance in any event. It can also be used as a pull-through insert where a stepped hole design is possible.
