@awesomeframers: Its the full length threading that matters, not the screw head. I love science and technology in construction. Drill would be faster, but can twist suddenly, so I'm using an an impact driver. 5 screws in under a minute = winning. "The SDWC is tested in accordance with ICC-ES AC233 (screw) and AC13 (wall assembly and roof-to-wall assembly) for uplift and lateral loads between wall plates and vertical wall framing and between the top plate and the roof rafters or trusses. It is code listed under IAPMO-UES ER-262 and meets 2018 and 2021 IRC® and IBC® code requirements for most common wood framing applications." . Next job we have quite a few interesting applications for structural screws. Always look at the total installed cost, not just the cost of the hardware, screw, etc. . #engineering #framing #technology #framer #toolsofthetrade #makitatools . @ISOtunes discount code Timmy10
