Dodge threaded inserts for plastics are brass screw machine products designed to provide strong metal threads in plastic components.
Dodge inserts are available in various knurl and undercut patterns to suit almost any threaded assembly application in plastics. They are 
designed to provide the high performance strength values of molded-in inserts while still retaining all of the economical advantages of 
insert installation after molding. 

Dodge brass inserts can be installed in a variety of ways. These include ultrasonic welding, hot or cold press-in, mold-in and self 
threading. Applications include the automotive, information technology, telecommunications, aerospace, defence, and medical 
industries.

In addition to the standard products, Dodge has also developed insert types and styles for specific applications. Designs such as studs, 
mold-in inserts, and compression limiters have been developed by Dodge.

•Installed ultrasonically or with heat

•Has same design characteristics as Standard Expansion Inserts
• Used extensively in electrical industry feature a pilot and a flange. The pilot can be clinched 
   over a terminal connector, eyelet fashion, with the flange providing a large surface for 
   electrical contact. The installation and clinching operations are simultaneous using a simple 
   press-in type tool
•Especially well suited for thin-section applications, since the downward force of installation 
   is absorbed by the flange

•Dodge Standard Expansion Brass Inserts are two-piece units consisting of a threaded insert 
   and a captivated spreader plate. When this spreader plate is depressed, the knurled portion 
   of the expansion insert expands, anchoring the insert in the hole
•Dodge Expansion Inserts must be expanded by depressing the spreader plate prior to insertion 
   of the screw as the screw will not expand the insert and lock it in place
•They are to be used in blind holes in thermoset or thermoplastic materials after molding
•Versatile — can be used in any type of plastic
•Easy to install by simply pressing-in. Installs without heat or ultrasonics
•If needed, the expansion insert can be installed to protrude above the surface of the part to 
   act as an assembly-locating device

•Dodge Compression Limiters are non-threaded bushings made of various materials
•Designed for applications where the tightening load of the bolt or screw will compress, crack
   or otherwise damage the plastic component
•Comes in various knurl configurations and undercuts to meet the strength requirements of 
   the specific application
•Custom designed for each application
•Can be pressed in or installed with heat or ultrasonics

Dodge Miniature Brass Inserts are designed to meet the requirements of today’s electronic, 
telecommunications and computer markets. The trend towards more miniaturised and compact 
consumer products has necessitated the use of smaller screws which must be reusable without 
the possibility of thread damage. 

Dodge Miniature Brass Inserts provide the strong, reusable threads designers need. They are 
available in two styles. 


Symmetrical Type Miniature Brass Inserts 
 
•Designed for high volume production utilising small screws
•Symmetrical design for eliminates need for special orientation of insert prior to installation, 
   saving time & production costs in the process
•Inserts can be loaded into an automatic feeding system, without the need for special 
   orientation
•Can be installed with heat or molded-in place


Flanged Type Miniature Brass Inserts 
 
•Designed to be installed into straight holes in thermoplastics or structural foam materials
•Lead-in pilot at the front end of the insert accurately positions the insert prior to installation
•Designed with opposing diagonal knurls that provide excellent torque resistance and 
   undercuts for tensile strength
•Flange provides a larger bearing surface which is advantageous in weaker plastics, ideal for 
   electrical contact, and provides high strength in reverse screw entry applications
•Can be installed with heat or molded-in place

•Ultra-Mold Brass Inserts are designed for applications where a molded-in insert is more 
   economical than post molding
