Quantity
When structural integrity and long-term reliability are non-negotiable, Qishine’s ASTM A194 2H Galvanize Nuts stand as the definitive fastening solution. Engineered for high-pressure, high-temperature, and corrosive environments, these nuts are manufactured in strict compliance with the API 20E BSL2 standard—a rigorous certification that guarantees traceability, material integrity, and process control from raw steel to finished product. This isn’t just a fastener; it’s a fully documented component built for the world’s most demanding industrial applications.
Superior Material & Mechanical Performance
Fabricated from premium carbon and alloy steel under the ASTM A194 2H specification, these 1-1/4 inch heavy hex nuts deliver exceptional mechanical performance. The material is quenched and tempered to achieve a perfect balance of core hardness and surface toughness, translating directly into an impressive load-bearing capability and superior resistance to fatigue, galling, and thread stripping. In critical bolted joints—such as those found in pressure vessels, wellhead equipment, and structural steel frameworks—the ASTM A194 2H grade provides the necessary yield strength to maintain preload under fluctuating thermal and vibrational stresses, ensuring a permanently secure connection.

Advanced Corrosion Protection
Beyond its mechanical strength, the ASTM A194 2H Galvanize Nut is distinguished by its vibrant, high-visibility yellow zinc-plated coating. This electroplated layer serves a dual purpose: it provides an appealing, clean aesthetic for ease of quality inspection, and more importantly, it acts as a sacrificial barrier against oxidation and atmospheric corrosion. The galvanization significantly extends the service life of the fastener, reducing total cost of ownership by minimizing maintenance cycles and premature replacements in offshore platforms, petrochemical refineries, and power generation facilities. While this yellow zinc finish offers excellent protection for moderate environments, we also recommend it as an optimal pairing with externally threaded fasteners of compatible coatings to prevent bi-metallic interaction.

Precision Engineering for Assembly Efficiency
Performance in the field begins with precision in the factory. Each Qishine ASTM A194 2H Galvanize Nut features high-accuracy Unified Thread Standard (UNS) threading, cut to precise Class 2B tolerances. This ensures a perfect, secure fit and smooth, effortless assembly and disassembly during installation. The wider bearing face of the heavy hex pattern distributes the load more evenly across the mating surface, eliminating the need for washers in many applications and preventing joint loosening. This dimensional stability is a cornerstone of BSL2 manufacturing, where every batch is rigorously tested for thread dimensions, proof load, and hardness consistency.
