Stainless Steel 420 U-Bolts & J-Bolts

Stainless Steel 420 U-Bolts and J-Bolts are specialized fasteners primarily used for clamping and anchoring. **U-bolts** are bent into a 'U' shape with threads on both ends, mainly used to support piping, tubes, or other round objects. **J-bolts** are shaped like a 'J' with a thread on the longer, straight end, typically used as anchor bolts for embedding into concrete or foundation material. Both are manufactured from the **martensitic stainless steel grade 420**, allowing them to be heat-treated to achieve significantly higher tensile strength and hardness than standard austenitic grades. **Zeron Fasteners** supplies these critical components for applications requiring superior holding strength, wear resistance, and moderate corrosion resistance, such as in heavy machinery mounting, structural framing, and high-stress piping support systems.
