Meta Description: Secure your critical pressure vessels with our 1-7/8 inch ASTM Zinc Plated Thread Rod. Featuring 8 UNC threads, API 20E compliance, and Bichromated finish for superior outdoor corrosion resistance. Engineered for reliability.
Solve Fastening Failures in Demanding Environments
When standard fasteners corrode or fail under pressure, the safety of your entire operation is at risk. Our high-tensile ASTM Zinc Plated Thread Rod is engineered specifically to solve these challenges in pressure tank installations and harsh outdoor settings. Measuring 1-7/8 inches in diameter with 8 UNC threads, this rod provides a robust, permanent clamping force that maintains joint integrity where safety is non-negotiable.

Engineered Strength: ASTM A193 B7 Chemistry
At the core of this fastener’s reliability is the ASTM A193 B7 grade alloy steel. This chromium-molybdenum (4140/4142) material is quenched and tempered to deliver exceptional tensile strength, typically exceeding 125 ksi. This metallurgy prevents the stripping and necking common in lower-grade fasteners, ensuring your flanges and pressure boundaries remain sealed under thermal cycling and mechanical vibration. It is the definitive bolting choice for petroleum and chemical processing equipment.

Dual-Layer Corrosion Protection: Zinc + Bichromated Plating
Outdoor and caustic environments rapidly degrade standard black-oxide fasteners. We solve this with a specialized duplex coating. First, the rod undergoes hot-dip galvanizing, creating a thick metallurgical bond that acts as a sacrificial anode. This is then enhanced with a Bichromated Plated finish—a chemical conversion coating that seals the zinc layer, preventing “white rust” and extending the service life significantly beyond standard galvanized products. This combination ensures easy removal and structural longevity, even in marine or industrial atmospheres.

Certified Compliance: API 20E for Critical Supply
Supply chain integrity is as crucial as the product itself. This ASTM Zinc Plated Thread Rod is manufactured in strict accordance with API 20E, the standard for alloy and carbon steel bolting used in the petroleum and natural gas industries. This ensures traceability, rigorous hardness testing, and Charpy impact verification. By choosing API 20E-certified stock, you eliminate the risk of counterfeit fasteners, ensuring your project passes audit requirements and operates safely.
