💡 What is the main reason contractors specify heavy hex structural bolts for steel frame erection?
Engineers require predictable yield points to guarantee safe weight transfer across interconnected truss members.
- Selecting the correct grip length stops incomplete engagement when bolting through thick column flanges.
- These handy hardened rods maintain tight friction angles while surviving repeated seasonal thermal expansion cycles.
- Rigorous quality testing verifies surface finish quality before shipment drops at busy regional yards.
