Secure and repair your door latches and hinges.

Patented technology that protects against forced entry

ZZem Screw is a simple and cost-effective door security solution. Out of an astonishing 2 million home burglaries each year in the USA, 60% gained access through the front door in seconds! (FBI Statistics). Most security technologies, like cameras and security lighting function AFTER the FACT. Most burglars don't care if you have a porch light or security camera. 

ZZem Screw extends the holding power of screws in hinges and latches deep into the door framing, reinforcing the weak points of your doors. This revolutionary design will help protect you and your family.

How does it work?

See the graphic below which illustrates how the ZZem Screw (bottom) dramatically increases the depth of attachment of the hinge or strike-plate to the door frame. ZZem Screw can be used to reinforce hinges, strike plates, deadbolts, and more.

  • 5 out of 5 stars

    Great solution, easy to install if you have a little sense. Reviewed in the United States on April 15, 2020 Item Package Quantity: 12Verified Purchase Great solution for blown-out hinge screw-holes. Used on a pantry door with a rack on the inside, probably weighs 50 pounds. Door is completely straight, no drag on the latch at all.

  • All I can say is WOW WOW WOW

    I tried the toothpick and golf tee, trick and non of them really worked or lasted long. I was destined to find a solution so I went on google and did some searching and I am across your product on Amazon. I was still a big skeptical but I bought it anyways. All I can say is WOW WOW WOW!! It worked perfectly and it’s as strong as can be now. Such an amazing idea and solution to a common problem.

  • I wouldn't hesitate at all to try these out

    Kudos to the creator of this product. It's high quality, made in America, and the packaging says it was invented by a veteran. That's a triple win in my opinion. I wouldn't hesitate at all to try these out.
