What are Threaded Inserts?


Groov-Pin Threaded Inserts are cylindrical, metal bushings with features on the outside which lock them into a plastic
or metal base material to anchor your fasteners. Our Threaded Inserts provide high-quality, permanent, wear-resistant internal threads

and are designed to be installed in molded or drilled holes in one simple step. While each style performs in a range of

materials, they are generally classified by method of installation: Thread-Cutting, Thread-Forming, Push-In, or Ultrasound.

Why do I need a Threaded Insert?
Threaded Inserts are designed to improve the strength of assemblies by distributing forces from the fastener over a large

area in the base material, thus increasing the load-bearing capability. For metals such as aluminum, this means full
utilization of high-tensile-strength fasteners. In plastics, Threaded Inserts avoid wear and cold-flow problems
encountered with thread-forming screws. Threaded Inserts offer both engineering and cost economies.

Why choose Threaded Inserts over wire coil inserts?

Strong and Reliable

    • Tap-Lok®s provide 1.5x higher pullout resistance
    • Tap-Lok®s provide a pullout resistance 2x that of a tapped hole
    • Our threads are permanent and still meet specifications from the factory through numerous screw removal/insertions
    • Improve assembly strength                    
    • Increase load-bearing capabilities
    • High-quality, permanent, wear-resistant

Easy to Install
    • One step installation vs. 3 steps for wire coils               
    • Cut down labor costs
    • No special tools are required for installation
    • Threaded Inserts install first time, every time
    • No tangs to break off and remove

Broad Product Line
    • Threaded Inserts for different installation methods: Self-tapping, Ultrasonic, Press-in, Molded-in
    • Threaded Inserts for metals, hard and soft plastics, and wood
    • Threaded Inserts made of steel, stainless steel, and brass
    • Variety of finishes and protective coatings available

How do they work?

Since Threaded Inserts are generally classified by method of installation, each type of insert has its own unique function. Here is
a breakdown of how each type works:

Exterior lobes are designed to roll through the base material and lock the insert in place without leaving chips behind. The wave gently rolls through the base material pushing it back and then allowing it to return behind the wave crest to securely lock the insert in place.

Installation tools for Tap-lok® thread-cutting Threaded Inserts and Speedserts®
thread-forming Threaded Inserts feature hardened studs for twisting the threaded
insert into the base material and a release mechanism
for easy removal of the tool
once the insert is locked into the
base material.

For installation, the insert is twisted onto the tool stud and into contact with the
tool nose piece. The tool is then used to twist
the Threaded Insert into the base

To remove the tool from the insert, the insert must be released. Production tools
automatically release the insert when torque
on the tool is reversed. Hand tools must be released manually.


Hand Tool Installation
To Install:

1. Install hand tool in a holding device such as a drill press
     chuck or hand-tapping fixture to assure perpendicular
     alignment with work.
          Caution: Do not use power.  Chucking the hand tool
          on a drill press is for alignment purposes only.
2. Screw insert on stud until it contacts nut.
3. Install to correct depth in the drilled hole.
4. Hold stud against rotation and loosen the nut with a wrench.
5. Unscrew stud from the insert.

Field Installation:

Threaded Insert Installation_Threaded Insert Field Installation_How to Install Threaded Inserts_Manufacturing_Groov-Pin


Threaded Inserts_Hand Tool Installation_How to Install Threaded Inserts_Manufacturing_Groov-Pin

It is important that the installation tool is squarely aligned with
the work surface.

Field repairs can be made by using the hand tool in conjunction
with either a carpenter’s brace or a speed wrench.


Drill Press Installation - Production Tool
3 Easy Steps:


1. Bring end of nose piece tightly against surface of material.  Hold in position.
2. Lock spindle in position.
3. Set drill press stop. (Readjust stop after testing
     for exact insert depth.)  Release the spindle lock.

After set-up is complete, hold the insert so that the rotating tool
drive stud will thread into it. Hold the insert by the outer thread
until it is snug against the nose piece.

Maintain the speed of the installation stud to between 100 and
500 RPM.

  Watch it in Action!

Important Notes

1. High-volume users are advised to order replacement studs when placing     insert order.

2. Special tools are available for installing threaded inserts into deep recesses and close to obstructions.

For further information, contact Customer Service

To Order Production or Hand Tools:

Specify the tool number for the internal thread size of the thread-cutting or thread-forming insert desired.

To Order Replacement Parts:
Replacement studs and now pieces can be ordered for production tools.  Specify the production tool number with a suffix:

Stud = ST
