Details on thread types (Unified National Coarse (UNC), Unified National Fine (UNF), metric coarse/fine) and thread class standards (e.g., ASME B1.1 Class 2A) are also vital for proper nut and washer compatibility.
The width of the gap inside the "J" bend.

The total vertical distance measured from the top of the threads to the inside bottom of the hook bend. Hook Length (H): The shorter vertical leg of the "J" shape.
Embedded directly into wet concrete pours to anchor structural steel columns, light poles, highway signs, and building sills.
J-bolts detailed in manufacturer catalogues are vital components across several sectors:
Are you anchoring a fire hydrant (exposed to road salt) or an indoor conveyor system? Open the PDF and search (Ctrl+F) for "galvanized" or "stainless." When searching for the right product, you will
|_| <--- Thread Length (T) | | | <--- Bolt Diameter (D) | | | <----- Length (L) / | <----- Inside Radius (R) \_/ <-----> Hook Length (H)
Ensure the catalogue specifies whether the bolts use UNC (Coarse), UNF (Fine), or Metric thread pitches. Coarse threads are preferred for concrete embedding due to rapid assembly.
The section of the shank cut or rolled with threads to accept nuts and washers.
The standard specification for anchor bolts designed for structural steel support. It comes in three grades: Grade 36, Grade 55, and Grade 105 (representing minimum yield strengths in ksi). This link or copies made by others cannot be deleted
The length of the short, turned-up end of the "J".
While custom manufacturing is common, standard commercial catalogs generally conform to the following baseline dimensions (listed in inches): Nominal Diameter (D) Standard Hook Length (H) Minimum Thread Length (T) Common Lengths (L) 1/2" - 13 5/8" - 11 3/4" - 10 10" to 30" 7/8" - 9 12" to 36" 1" - 8 12" to 48" 4.
