Review on GRK RSS3812HP HandyPak 12 Inch Structural by Gary Shakeone

After years of driving 10, 12 and 14 inch regular cotter pins into 6x6 rods for dock hull building and repair, I replaced these construction screws with GRK . You passed the exam. as well as traditional spikes in side-by-side installations subject to ice crushing and flooding. Bolts are not easily removed, but unlike spikes, they can be driven in and then removed, for example if you need to temporarily attach a joist. In addition, unlike the hammer blows required for the mandrel, the screws are screwed in quickly and silently, labor productivity is much higher.
