  • Tough screws
Color: Zinc
These screws are good quality and work best if you use a square head driver vs Phillips.

  • Great product
Color: Zinc
Excellent product. Easy to install

  • Better security in an inexpensive kit.
Easy to replace the short factory screws with these longer screws. Much more secure now.

  • Perfect screws for what I want.
Color: Zinc
I bought these screws to attach a lock to my door frame, in such a way that it will be sturdier, last longer, and be more difficult to break. I used these to replace the 2 1/2 inch screws that came with the lock, as those screws were Phillips head, which are notoriously easy to strip and damage. These screws, however, are easier to drive and much more difficult to strip. Which is exactly what I was looking for. All in all, I am very satisfied with my purchase of these screws. ... show more

  • Used to reinforce exterior doors and bolt plates
Color: Zinc
Good screws, perhaps too long. I pre-drilled the screw holes with wood drill before I installed screws.

  • Solid upgrade, big impact Solid upgrade, big impact
Color: Zinc
After doing a bit of research, I decided to go with this Reinforced Door Screw Kit, and I’m really happy with the choice. These screws are solid. Once installed, the doors immediately felt sturdier, and it’s reassuring to know there’s extra protection in place. It’s a small change that makes a big impact. I’d definitely suggest this to anyone looking to step up their home security. Installation was very easy. ... show more

  • Great screws!
Color: Zinc
The dual-formed screw head accepts both standard Phillips and square screw driver bits, in which the latter is much easier for non-licking secure installation. The screw is a little bit thinner than regular door hinge screws probably for easy installation without pre-drilling. If you think the existing jam hole is larger and worry if the screw would install loose, pick a toothpick, coat it with wood glue, then strike it into the hole. It is also recommended coating the screw with lubricant like toilet bowl ring wax for easier self-drilling. The caveat is that it is pricier than other screws, but it's probably worth the price. ... show more
