Ultimate tensile loads As × fu are shown for selection only – anchor design checks steel, pull-out and concrete failure.
Types
L and J bolts rely on the bend for anchorage and suit pinned bases; headed bolts – with a hex nut and plate washer at the bottom – carry higher tension through bearing on the concrete. Straight rods with an embedded plate are used for tall piers; hammer-head bolts fit cast-in anchor channels.
Fabricated in our plant
Anchor bolts are cut, threaded, bent and galvanized with the column steel, so the bolt pattern, projection and base plate holes come from the same model. Threads are protected with tape or caps for shipping.
