ASTM A193 Grade B7/B7M Short Threaded Rods – Yellow Zinc Plated

Product Overview: Our ASTM A193 B7/B7M short threaded rods are designed for high-stress applications requiring both mechanical strength and enhanced surface protection. These rods are manufactured from quenched and tempered Chromium-Molybdenum alloy steel. The Yellow Zinc finish provides a thicker protective layer and superior salt spray resistance compared to standard clear zinc. The B7M version is precision-treated to a maximum hardness of 22 HRC for specialized use in sour gas (H2S) environments. Key Features: • Superior Corrosion Resistance: The Yellow Zinc (Cr6+ or Cr3+ options) coating provides an extra layer of protection against moisture and industrial chemicals. • Specialized Heat Treatment: B7M variants are strictly monitored to meet safety standards for stress-corrosion cracking resistance. • Precision Short-Cut: Professionally cut to specific lengths with clean, chamfered ends for immediate, hassle-free installation. • Full Traceability: Every shipment is backed by a Material Test Certificate (MTC) ensuring compliance with ASTM A193.
