Multifit - Unheaded - Short - M4

Unheaded Multifit Short inserts are compact multi-purpose brass threaded inserts designed for use in plastic injection mouldings where material thickness is limited. Featuring an external barb form, they offer excellent flow characteristics during installation and deliver high pull-out performance across a broad range of thermoplastic materials.

Suitable for press-fitting, heat insertion, or ultrasonic installation, performance can be optimised by selecting the appropriate fitting method for the application.

The precision location spigot ensures accurate alignment in drilled or moulded-in holes, enabling consistent, square installation every time. The Short variant is ideal for lightweight or space-restricted assemblies where reduced insertion depth is essential. For applications requiring greater engagement length and increased load distribution, consider our Multifit Regular Inserts.
