ASTM A307 Grade A U-Bolts and J-Bolts

ASTM A307 U-Bolts and J-Bolts are specialized fasteners made from low-carbon steel that are bent into specific shapes for unique anchoring and pipe restraint applications. U-Bolts (shaped like the letter 'U') are used to secure piping, tubes, or other round objects to structural supports, while J-Bolts (shaped like the letter 'J') are often used as embedded anchor fasteners in concrete foundations or as hanging hooks. These bent bolts are covered under A307 Grade A, meeting a minimum tensile strength of 60 ksi, making them suitable for general-purpose, non-critical assemblies and restraints. Due to their simple yet effective design, they are indispensable in HVAC, plumbing, and general construction for providing reliable support and attachment points. Zeron Fasteners manufactures and supplies these U-Bolts and J-Bolts in various configurations, including finishes like hot-dip galvanizing for long-term corrosion resistance.
