Before choosing an anchor bolt, it's critical to understand what forces it must resist. Consider:
Tensile, shear, and combined loads
Vibration or dynamic forces
Safety factors and design codes (consulting a structural engineer is highly recommended)
Bolt selection must match both the expected load and the code requirements for your region or project type (such as DOT, AISC, or ASTM standards).
The material the anchor bolt will be embedded into - and the surrounding environmental factors - play a major role in performance.
Concrete, brick, block, stone, or CMU all require different anchoring approaches.
Corrosive environments, moisture, freeze/thaw cycles, and chemical exposure can all affect bolt longevity and coating selection.
At Threadline, we manufacture and supply a wide range of anchor bolts to suit every application - from light-duty construction to heavy industrial foundations. Here's a breakdown of our most popular options:
Heavy-duty, adjustable anchor bolt ideal for machinery and equipment bases
Includes leveling nut for precise installation and load locking
Designed to handle dynamic loads and vibrations
90° bend for secure embedment in concrete
Commonly used to fasten sill plates or structural steel to foundations
Bent into a hook on one end, threaded on the other
Often used for temporary anchoring or light-duty embedded applications
J-shaped bolts offer reliable embedment and pull-out resistance
Common in highway, infrastructure, and foundation applications
Custom Bent Bolts
Fabricated to exact specs (angle, length, diameter)
Often used in custom applications and include tack-welded heads or special bends (e.g., 22°)
One end forms a loop (welded or formed) to attach cables, rods, or hooks
Other end is threaded for secure fastening
"U"-shaped with threaded ends
Designed for fastening round objects like pipes or conduit to flat surfaces
