Grades 36, 55, and 105 (common for structural anchoring). ASTM A307/A193: For lower/higher strength requirements. ISO Gr 4.6, 8.8, 10.9: Metric strength grades.
If standard sizes from a manufacturer catalog do not fit your blueprints, you can specify custom configurations using this order string format:
J-bolts are cast-in-place fasteners, meaning they are positioned in the concrete formwork before the concrete is poured. After the concrete cures and the formwork is removed, the threaded, straight end of the J-bolt protrudes from the concrete surface. This threaded portion is then used to secure structural elements, such as steel columns, machinery bases, or light poles, using nuts and washers.
The catalogue then provides a table: For a 3/4″ J-bolt embedded 5″ into 4,000 psi concrete, the ultimate tension capacity is 12,480 lbs, with a recommended safe working load of 4,160 lbs (using a safety factor of 3). Without this table, you might over-tighten the nut and rupture the concrete cone. j-bolt catalogue pdf
J-bolts are used in a wide range of applications, including:
Environmental conditions dictate the material and coating choices listed in a supplier's inventory.
: To prevent rust, catalogues offer finishes such as Hot-Dip Galvanized , Zinc Plated , Black Oxide , and PTFE Coating . Common Applications Grades 36, 55, and 105 (common for structural anchoring)
6. What to Look for in a High-Quality Manufacturer Catalogue
Lighter-duty J-bolts are frequently used to hang or support electrical conduits, plumbing, or HVAC piping from structural steel beams. Instead of being embedded in concrete, the hook wraps around a structural lip or pipe, and the threaded end is secured with a nut and washer through a mounting bracket. Roofing and Cladding J-Bolts

The length of the usable, threaded portion at the straight end of the bolt.
Anchoring highway guardrails, bridge railings, and overhead sign structures.
Availability of material traceability documentation proving the chemical and physical properties of the steel.
A J-bolt is a type of foundation bolt easily recognized by its shape: a straight, threaded shaft that bends into a curve at the end, forming the shape of the letter 'J'. This J-shaped bend is embedded into concrete before it cures. Once the concrete hardens, the bend acts as a powerful anchor, providing exceptional resistance against pull-out forces.
