Review on πŸ’§ Enhanced Moisture Barrier Performance of Concrete Screws by Matthew Baltimore

Revainrating 5 out of 5

By TapCon, Hello Red Seal

Finally a quality product with a useful function. Don't get me wrong, I always stick with MITUSA when making a decision based on quality over price. This might be one of the few exceptions. Made in Taiwan - this is practically given, since the quality will be very high. I've driven concrete anchor bolts into more rock foundations than tiger knock-in tees. An inherent problem with concrete anchors is that very dense but brittle materials including (obviously concrete), brick, natural stone and even porcelain will shatter when drilled. This is the number one annoyance, namely the tendency of the screw to "unscrew" out of the hole. There's also a trend - in my experience with the most well-known brand of concrete anchors for their Phillips head lag screws (pro tip: don't use Phillips head screws from Tapcon, your screwdriver will likely come out before your screw is fully seated. Use their hex socket wrench and a good quality impact wrench). In order not to contradict myself, I would like to explain the difference with the Red Seal screws. The head size of this screw is a very deep hole for a #3 Phillips screwdriver that fits very snugly in the screwdriver (included). A high torque is also applied when screwing in concrete screws with a percussion drill. Breaking off screw heads is common. I haven't had a single red screw failure. Regardless, it takes a very dexterous hand to properly drill holes in concrete (most beginners don't use water when drilling concrete - USE water to both cool the bit and create the "mud" that needed to create a smooth, even cavity for drilling). screw). So I'm giving these bolts a 5 star rating due to the addition of angel wings (and their high torque strength). They provide both a countersink effect and a rubber seal for a precise fit. On that last note, I would like to point out that there is strangely very little competition in the concrete screw market. Tapcon has a virtual monopoly (and they charge a fee). For the record, the drill bit that comes with the red seal screws is not meant to be worn for long, so make sure you use A. a good quality Bosch or other high quality drill bit (often made in Germany, these are the longest lasting seem to hold up). ) and B. Use plenty of water when drilling (don't worry your drill chuck will get a little wet, centripetal force will prevent water from entering the drill chuck). Pro Tip #2: Use a sponge as a source to mist the chisel with water all the time while holding the chisel steady and level (in a straight line with the hole you're drilling) so no sideways Movements can arise a larger diameter. what is needed to ensure the screw is tightened well. Also, while drilling, without stopping the drilling speed, pull the bit out several times to allow the water to cool the bit and "suck” the mud out of the hole. I hope this helps, but again this is just an opinion based on my experience. Have fun drilling!

Pros
  • FOR LIGHT CONCRETE: durable and strong.
Cons
  • Not as thick as other picks
