Fastener Features – MAThread® and MATpoint®

Fastco is MAThread® and MATpoint® licensed. These patented thread types are heavily relied upon in automotive applications because they eliminate seizing and jamming of fasteners with anti-cross thread technology. This is especially beneficial for difficult, high-volume assemblies, reducing cost by eliminating the need for expensive reworks caused by cross or false threading.

Many automotive OEMs consider MAThread® to be the standard for externally threaded fasteners. These include GM, Ford, Chrysler, Mercedes Benz, Volvo, and VW.

Fastco can manufacture all of the following types of MAThread® Fasteners:

 

MATPoint

The most common design, MATpoint works effectively in most applications, except for when prying heavy components into place during an installation.

Very Short MAThread

As indicated by the description, this design has a very short end point. Therefore, this design works best for applications with problematic point clearance and limited angular misalignment.

Dog Point MAThread

Dog Point MAThread performs best on any difficult application or when prying heavy components into place during installation.

“P” Point MAThread

This design works best with difficult applications when the point clearance will not be an issue. In addition, it works well with thick stack-ups of multiple components.

Never-Jam™

If packing length and/or weight is a concern, this is the thread to use. It is effective up to and including 12 degrees misalignment.

Custom MAThread

MAThread can customize design criteria for special applications.

 

Key Features of MAThread® and MATpoint®

Key fastener features of MAThread® and MATpoint® include:

• Self-correcting: This makes thread damage or seizing impossible.
• Easy-to-use: This allows any installer to use them without fear of fastener or part damage
• Customizable: MAThread can meet customer’s specific needs.
• Always improving: The design is regularly reviewed and made better.

 

In addition to automotive, MAThread® design can be used in a wide variety of industries, including construction, heavy equipment, motorcycles & recreation vehicles, and water craft.

For the last decade, Fastco has worked to increase our in-house tooling capabilities. From making less than a quarter of our tooling in-house, we’ve expanded to making about 80% of our tooling within our three onsite tool rooms.

Making our own tooling allows us to save money and time; we can make a tool set in less than half the time it would take to purchase one. This means we can pivot quickly on design changes and get prototypes out the door quickly.

 

 

In-House Tooling Improvements

In recent years, we have made some significant investments in our tooling equipment, including:

1. A Sodick VZ300L Wire EDM machine, which opened up our capabilities with shaped inserts and trims.

   

2. Our CNC Mills (including a Haas VF2 CNC Mill and a Haas CNC Mini Mill), which we use to make our own knurl dies in-house.
3. A Haas TL1CNC Lathe, which has expanded our forming of steel solid pockets and punch inserts.
4. A Weldon CNC ID Grinding Machine, which reduced costs for some of our most expensive tooling (pocketed and tri-lobular inserts). Most importantly, its high level of precision allows us to get an exemplary surface finish, improving the performance of these tools.

   

5. A laser marking system, which allows us to make all marking tooling in house at a near-zero consumables cost.

 

 

Why In-House Tooling?

Manufacturers that make their own tooling provide a huge value benefit to customers for the following reasons:

1. Decreased Lead Time: The current lead times for most purchased tooling is upwards of 8 weeks. We can make our tooling in less than half that time. If a design change happens, we work on the fly to change out the tool sets. If there is an out-of-stock scenario, we won’t need to short orders while we wait for tooling; we also won’t need to set up the machine again, adding wasted cost. If a customer needs prototype parts in less than 8 weeks, we can typically make that happen.
2. Improved Control Over Quality: Making our own tooling allows us to produce better parts. Our tooling produces a superior finish on parts with tighter tolerances and a better total indicator reading (TIR). If we struggle with forming a part on a machine, we can  make tooling adjustments to improve the quality of the part.
3. Lower Cost of Tooling: Not having to order tooling cuts down on freight costs. Making our tooling reduces costs associated with unnecessary downtime. It also reduces the need for extra outside processing trips and unnecessary extra setups.

 

 

Fastco’s Tooling Equipment

Fastco has a wide-range of tooling manufacturing equipment, including:

• Manual ID, OD, and Surface Grinders
• CNC ID & OD Grinders
• Honing equipment
• CNC Lathe, as well as manual and speed lathes
• CNC Mills and manual mills
