About

The Top Surface of Pact Plate
The Bottom Surface of Pact Plate

While there are many different modular bolt-together building systems to help create your hardware projects, there really aren't any good options when it comes to simply mounting things on a rigid flat surface. You always seem to have to custom fabricate a surface, and usually end up using a flimsy and cheap board material that can't be used again on another project. So, if there are so many easily reconfigurable modular framing systems, why isn't there a modular and reusable solution for the base plate, or the foundation of your hardware projects? The answer is Pact Plate!

36 Individual M4 Threaded Holes - Use widely available M4 machine screws and bolts to attach things to the plate form either side. Holes are spaced 25.0mm apart [~1in].

4 Individual Recessed Holes - M4 sized Recessed holes near the corners of the plate so Pact Plate can be mounted to any material, and then the mounting screw head will not interfere with the top surface.

Very Strong and Stiff Injection Molded Plastic Alloy - Pact Plate is made of a special injection molded plastic alloy widely used in the automotive industry to replace die cast aluminium. This tough and robust material gives Pact Plate similar material properties to die cast aluminium.  

3 Individual Screw Holes in Each Side - Holes are spaced and sized to provide maximum strength when joining plates together, using the included fasteners. 

Clearly Marked Side A and B - To join plates together, simply match side A to B.

Clearly Marked Nut and Screw Mounting Locations - Shows you which fastener to insert to join plates together.

All Metal Threads - All 36 mounting threaded holes on Pact Plate are made of metal, so they are built to last and can withstand tons of repeated uses.

High Strength Pact Plate Injection Molded Plastic Alloy - Pact Plate is made of a special injection molded plastic alloy widely used in the automotive industry to replace die cast aluminium. This tough and robust alloy material gives Pact Plate similar material properties to die cast aluminium, yet at a much lower cost. For comparison purposes, in the image above we hang 5lb [2.3kg] weights off the ends of each identically sized [88 x 50 x 2.5mm] real molded material sample. The Pact Plate plastic alloy has a similar deflection to the die cast aluminum, yet a typical plastic, such as the PC/ABS used here, does not have the rigidity.

Above is a video of showing how the 5lb [2.3kg] weights are hung off of the molded material samples in the test fixture.

Included High Quality Hardware with Built-in Locking features - Each Pact Plate comes with six high quality M4 screws and square nuts. The screws all feature a special yellow patch on the threads that locks them in place and prevents them from vibrating loose when you join plates together. The screws are fully reusable and will retain their built-in locking features for multiple uses.

Mount Pact Plate to any Surface, Material or Modular Framing System - The four Recessed holes near the corners of the plate allow a variety of machine, wood, or sheet metal screws to be used to attach Pact Plate to any surface. Easily attach Pact Plate to your workbench to create the ultimate workbench. Pact Plate is also compatible with any modular structural framing system.

Assembling Pact Pact in any size and shape to fit your project is easy. Here is a real time video of how plates are joined together, including how the fasteners are inserted into the plate and how they assemble together and apart using the included hex wrench:

Pact Plate can be easily assembled into any size and shape to fit your project needs. But was designed to also be used by itself as a single plate - with no protruding features on the sides, you have a simple square plate to work with, making project integration much easier.

Once you have the Pact Plates assembled to the desired size and shape, you can simply bolt things securely down where needed. When you are done with your project, everything can be easily taken apart and reused for the next project!

The possibilities are endless with Pact Plate! There are so many project applications for crafting, DIY, electrical, mechanical, organization and industrial uses.

Pact Plate has been designed with the worldwide standard metric system in mind, yet all key dimensions are also directly comparable to whole numbers in inches.

High Quality - Pact Plate has been designed to be made with the highest quality materials and processes. Quality assurance, dimensional Accuracy and flatness of every single Pact Plate will be our priority.

What's in the Box? - Each and every Pact Plate comes with the hardware you need to join any amount of plates together by including:

  • Pact Plate
  • Fastener Kit containing 6x M4 screws with nylon patches and 6x M4 square nuts

Hex Wrench - Every single order comes with one 3mm Hex Wrench to easily help you join plates together and assemble anything on the Pact Plates. This specially designed wrench features a short length section on one end to get into tight spaces and a ball end on the other to allow fastening screws at an angle.

Packaging - Each Pact Plate will be securely packaged. The above image shows our prototype retail packaging for each individual Pact Plate. When an order is placed, this retail packaging would go into a shipping box for extra safe transport.

Current Status - Prototype testing is complete and the production drawings are ready. We already have Pact Plate quoted and set up with two factories that are standing by and ready to begin the injection mold tooling and production once the campaign is funded and ends.

Pact Plate Rewards use a Quantity Discount system; the more plates you order the lower the cost is per plate!

Dozens of generations of Pact Plate Prototypes

Pact Plate all began with a problem that needed solving. In 2017, Jim was looking for some different sized rigid surfaces to mount some test fixtures and a drilling jig to. The typical unsatisfactory choice was to mount them to a piece of flimsy plywood, but this would just not be sufficient. Like any early stage project, it would be evolving and the mounting locations would be changing, measuring and drilling holes at different times in the process would be cumbersome. Square profile T-slot aluminum framing was considered, but it's main function is simply to form the frame of the system, and definitely not a solution for covering a wide flat area to which you can mount things to. With no practical options available, Jim came up with the concept of a reusable modular base plate system, where rigid plates with standard threaded hole patterns could be linked together to accommodate projects of any size and shape. After dozens of generations of 3D printed prototype designs, metal threaded insert testing, materials research, and beta testing, we have arrived at the final production prototype and are excited to bring Pact Plate to fruition. 

What's in a name? - What does "Pact Plate" mean anyway? "Pact" is a Latin root meaning "to fasten" - we thought it was very fitting!

Jim in his 3D Printed Kayak

Jim is an avid maker, mechanical engineer, DIYer and creator of all things mechanical. Looking around the maker community, Jim sees that there are thousands of projects that can benefit from Pact Pate and wants to help them solve a real hardware need that is currently without a practical solution.

Risks and challenges

While there are always risks and challenges in creating and producing any product, we are confident in our abilities to overcome them all. We have many years of experience in bringing high-volume, complex electro-mechanical products to the consumer and industrial markets.

The production design and drawings are ready. We already have Pact Plate quoted and set up with two factories that are standing by and ready to begin tooling and production once the campaign is funded and ends. We have taken many things into account, such as all of our previous production experience and new international tariffs, and factored them into and adjusted our carefully planned timeline, rewards pricing and campaign goals.

We are completely prepared to deliver Pact Plate to you, and we have the plans and the know-how to make it happen, but should anything come up along the way, you will always be the first to know.
