M3 0.5x4mm Torx Screws and Driver



NOTE: These screws are not compatible with the Molecule RDA.

Tired of stripped screws? So were we and that was one of the reasons we decided to build the Boaz RDA. One of the best features about the Boaz RDA is the Torx screw we use on the posts which allow you to get your legs tighter than ever before and without stripped screws! 

We've decided to make our high quality gold plated Torx screws available to you to retro fit into other RDA's or RTA's that use M3 0.5 x 4mm. M3 is the size of the screw, .5 is the thread size, 4mm is the length. Most of the newer devices use this size, such as the Recoil Rebel RDA, Dead Rabbit RDA, and many more.

We'll be offering M2.5 screws soon for the smaller or older devices!

*Warning: These screws are capable of applying more torque than traditional grub screws and the posts in the Boaz RDA were designed to handle this extra torque. Use caution when tightening these screws as you could over tighten and cause damage to the thread of your posts. Use at your own risk, we are not liable if you damage your device. If this is a concern we advise checking out our Boaz RDA!

These are excellent. They feel solid as hell when you are tightening down on those exotic coil leads. Especially on those smaller rdas that require you to stack your leads on top of each other. Also bought the hex core fused clapton spool, and I prefer smaller chambered rda's, so generally I have to stack leads in the positive post. That's a total of 14 small wires. We all know that requires some serious torque so that screw doesn't loosen and you get the dreaded "atomizer short* in your screen. No longer do I get that nervous feeling as I use the necessary torque to accomplish what's necessary. If you haven't experienced a stripped grub screw in an RDA before oh, lucky you. That shit sucks. As for the product, absolutely, 100% a definite five star product. The only reason I chose for stars for this review is because I feel like 7 Bucks is a bit too expensive for 10 screws. Now, no offense to anyone at Advanced Vape, but that's almost a dollar screw. Not sure what they cost to produce or buy wholesale, but the driver doubtedly cost more than 0.15¢ wholesale. As a hobbyist enjoys purchasing multiple products on what was already a tight budget, I would feel much more comfortable with maybe 15 included screws. An odd number I know, but we all have a three post rda somewhere. All in all though, if you've ever experienced a stripped grub screw, or are worried because that new rda has some suspect looking screws I would definitely recommend these.

Work Great

Easier to work with, love the torx drive. Looking forward to the 2.5 size for the tanks that need them. Will be getting more of these as needed. First rate service and decent prices will keep me coming back.

Great product for any rda or rta, if they use this size.

I use these in all of my rda's that will accommodate them. They grab the wire easily, from single wire to more complex and bigger builds.

Great set of screws and dr7iver

My experience has been great, I can get coil legs as snug as I want them now. Just be a little cautious in how much you tighten them, which is in the warnings/descripton. My girlfriend tightened one too much, on a dead rabbit and the coil broke. Awesome torx screws
