and hole depth heights in mm/inch/fraction

Using non-stainless fasteners with a stainless steel connector can compromise corrosion resistance and structural integrity at the connection point

Note: Fasteners (3/4" machine bolts) are not included and must be sourced separately

High Uplift & Lateral Resistance: SSTB-style anchor bolts and heavy-gauge beam seats work together to resist uplift forces during high-wind events

Why is ZMAX galvanization recommended for this connector

Simpson #12 x 2" Self-Drilling Flat-Head Screw with Wing, 410 Stainless Steel PACK:1000 Pk and hole depth heights inSimpson #12 x 2" Self Drilling Flat Head Screw with Wing is a precision engineered fastener from Simpson designed for securely attaching wood, plywood, and fiber cement to steel substrates up to 0. 209" thick. The winged drill point bores a clean clearance hole through the wood layer so the material does not climb the shank during installation then the wings snap off cleanly as the point contacts the steel, delivering a flush, professional finish.
