ASTM A307 Couplings

An ASTM A307 Coupling (often referred to as a Coupling Nut or Sleeve Nut) is a cylindrical or hexagonal fastener that is internally threaded along its length. It is designed primarily to join two externally threaded rods or studs, effectively extending the length of the assembly. The ASTM A307 specification covers carbon steel bolts, studs, and threaded rod with tensile strengths up to 60,000 psi, making these couplings suitable for general-purpose, non-critical applications like structural connections, pipe hanging systems, and simple machinery assembly. Zeron Fasteners manufactures and supplies these reliable couplings, ensuring they meet the prescribed standard for dimensional tolerance and material integrity, guaranteeing a strong and secure joint.
