DeadNutz Square - 3-1/2"The DeadNutz Square is machined to perfection using the latest technology, giving rise to its name. Dead nuts is a phrase for absolute precision. The term comes from the age of analog scales to describe where the measuring nut for the scale was set to read zero the basis from which all other measurements are taken precisely, 00. To ensure the DeadNutz Square lives up to its name, Woodpeckers uses Wire Electrical Discharge Machining (EDM) technology
The DeadNutz Square is machined to perfection using the latest technology, giving rise to its name. “Dead nuts” is a phrase for absolute precision. The term comes from the age of analog scales to describe where the measuring nut for the scale was set to read zero – the basis from which all other measurements are taken – precisely, “00.” To ensure the DeadNutz Square lives up to its name, Woodpeckers uses Wire Electrical Discharge Machining (EDM) technology that erodes the metal at the micron level, resulting in incredible precision and quality.
What sets the DeadNutz Square apart from its competition? Wire EDM manufacturing produces a level of precision that the woodworking market rarely experiences. For one, it is made from one piece of 3/8"-thick stainless steel, meaning there’s no opportunity for assembly error between the blade and the base. Because nothing is joining different materials or reference surfaces together, you can be sure there will be no warping. The edges are beveled for precise reference against the blade of your equipment, highlighting any light shining through. This, paired with the firm purchase of the flat base, will give you the utmost confidence that you are “dead nuts” square.
The DeadNutz Square is perfect for calibrating your equipment. Our wire EDM method allows each tool to be machined and inspected to a tolerance within .002⁰ or .0002" (yes...2 ten-thousandths). Bring that confidence to your shop setup, whether you are setting the jointer fence or bringing your compound miter saw back to 90⁰. It also makes quick work of aligning your table saw blade to a perfect 45⁰. At 3-1/2" tall, the DeadNutz Square is extremely versatile and can be used with everything from a scroll saw to a table saw.
After calibrating your equipment, quickly check that your cuts are spot on. The DeadNutz Square also provides an inside 90⁰ reference for quick and easy checks of your workpiece edges.
Simply put, the DeadNutz Square has no equal and will be the most reliable square in your shop!

Filter quality and value
Style: CF11809 Classic
2nd time to purchase this item over a 5 year period. The filter has a rigid frame making last much longer than other paper filters. Perfect fit and worth the cost. Great job filtering cabin and neutralizing odors!

Simple Upgrade That Makes a Real Difference
Style: CF10140 Classic
Installed the Zezut cabin filter in my 2005 Infiniti G35 and noticed the difference immediately. The air inside the car felt fresher and cleaner right away — no more stale air circulating through the vents. The HEPA backing is a big deal, knowing it's actually filtering out dust, pollen, and particles rather than just being a basic filter gives you real peace of mind. The quality feels solid and well made. Installation was super easy, took just a few minutes with no tools needed. For the price this is one of those simple maintenance upgrades that's absolutely worth doing. Your lungs will thank you. Great price and affordable, top choice for replacement in my opinion.

Efficient long lasting. Great Value
Style: CF10735 Classic
These filters (my second one) has lasted me over two years with a little maintenance in between, (removing from time to time to vacuum and shake out the bigger debris.) They do a great job of keeping the cabin air really clean and fresh.
1) Over designed and built (Good thing) installed without effort.
2) Fit and finish is perfect for my 2016 Genesis G80
3) Carbon filter works well but after about six months it no longer absorbs orders, This is excepted especially when I have not swapped it out for over two years.
4) Great value and honestly I should be replacing these cabin filters out ever six months for efficiency and order control.
Note: When I decided to replace it the filter held up structurally as the day I installed it. The charcoal beads where all intact as well.
