Product Overview

The GRK Fasteners RSS screw is made from Climatek coated and hardened steel. Its sharp threads and point bite instantly into material (including hardwood), reducing the splitting effect caused by smaller shanks. Its washer type head has no sharp edges like conventional lag screws and the added shoulder underneath the washer has the ability to center the RSS screw in predrilled hardware.
  • Ideal for ledger boards and more
  • Made of extremely high quality carbon steel that provides high tensile torque and shear strength
  • Self-tapping - no pre-drilling required
  • Installs with a standard drill
  • W-cut thread design
  • Climate corrosion resistant coating
  • Built-in washer
  • Sharp zip-tip point bites instantly into material for ease of starting with minimal force and reduce splitting
  • CEE thread design reduces friction and makes driving easier
  • Short rounded head provides low profile finish with no sharp edges
  • Excellent lag screw alternative

Do not use on exterior projects or PT wood
Completely corrodes into rust in a year. I built several projects with GRK and all screws are failing some are so bad the head breaks off. I am going to remove all of them and replace with stainless. Horrible product and waste of time and money.

    STRONG
    I used two to mount a BMW wheel on the wall of my garage. I pobably only needed one as i coud do chin ups on it! I tried to remove the coating with a wire wheel to get it silver but had to use a sanding wheel. Looks like it would hold up to the elements outside.

      I used these fasteners to hold 4' x 8' sheets of 1/4" peg-board to the wall with nylon spacers behind. Now there are shovels, rakes, pitch-forks and the like hanging on the peg-board. These fasteners might be above and beyond, but I do not have to worry about the things coming off the wall.

      I just had a new pole barn built, and the builders used these screws. It took a bit to find them, because they are not well advertised, but my wife found them at Home Depot. These screws are awesome. I had some customization on the new barn, so I bought two boxes of these, then 4 more for the farm. I liked the design and performance so well, I bought some #10's for smaller work. These screws drive easy and hold. If you wanted even better hold, get longer screws, but the ones I bought worked great through 2 inch wood. All in all, I can see me switching to these screws over lots of other kinds Phillips head screws.

      Like the screws, T30 tip design doesn't strip out . Threads grab well and using lower speed 1 the torque draws boards up tight. I Used hundred or so on my barn project. Expensive but worth it

      Although this product was not what I had intended to purchase (I was looking for #10 or #12 screws in 4-in or 4.5" lengths), they worked well for my project. I wish there were MORE options such as variability in package/qty sizes. I bought these (which were a larger OD than I initially intended) because the qty in the package was more suited to my needs. I'd buy again.
