Black Stud Bolts A193-B7 A194-2H - Yanzhao Fasteners | Corrosion Resistance, High Strength


Fasteners are the unsung heroes of modern engineering, providing the structural integrity that holds together everything from skyscrapers to microchips. Among the many types of fasteners available, A193-B7/A194-2H BLACK STUD BOLTS stand out as a critical component in industrial and construction applications. Manufactured by Handan Yanzhao Fasteners Manufactory Co., Ltd., these bolts combine durability, precision, and corrosion resistance to meet the demands of even the most challenging environments. This article explores the features, specifications, applications, and company background of these high-performance fasteners, while also referencing authoritative standards from the National Institute of Standards and Technology (NIST) to underscore their reliability.

Product Overview

The A193-B7/A194-2H BLACK STUD BOLTS are fully threaded rods designed for use in high-strength applications. These bolts are commonly referred to as "red rods," "TFL rods," or "ATR rods" due to their continuous threading from end to end. The black finish indicates a specialized coating, likely a zinc plating or other corrosion-resistant treatment, which enhances their longevity in harsh conditions. The product is available in two variants: A193-B7 and A194-2H, each tailored to specific engineering requirements.
