The Strong-Bolt 2 wedge-type expansion anchor is an optimal choice for high-performance even in seismic and high-wind conditions. Dual undercutting embossments on each clip segment enable secondary expansion should a crack form and intersect the anchor location; this feature significantly increases the ability of Strong-Bolt 2 to carry load if the hole expands. The Strong-Bolt 2 stainless-steel wedge anchor offers long-lasting corrosion resistance for a wide variety of service environments. Our Tests: 3/8"x3 1/2". 304 SS. We took 3 bolts up to 29 kN in Tension. Bolts were still in the concrete with no breakage. We stopped at 29 kN so we didn't break our test rig. Note: We asked, and the manufacturer informed us the nut and clip have not gone through a polishing finish, therefore they have a slightly different appearance.
