S-92186A952 1 1/8"-7 x 4 1/2" ASME B18.2.1 Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 Stainless Steel construction, ideal for marine, chemical, and outdoor applications
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under high stress
• Optimized load distribution through the partially threaded design, reducing thread fatigue and improving joint integrity
• Precise and secure fastening ensured by Class 2A thread fit and UNC coarse threads for easier alignment and reduced cross-threading risk
• High-torque installation capability with the external hex drive and large 1 11/16" head width, allowing for efficient assembly with standard tools
• Long-term durability with compliance to ASME B18.2.1 manufacturing standards, ensuring consistent quality and dimensional accuracy
• Environmentally responsible sourcing as the screw is RoHS 3 and REACH compliant, meeting stringent regulatory requirements for industrial use

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 1 1/8"-7 UNC hex head screw in 316 Stainless Steel addresses critical challenges like corrosion, vibration, and high tensile loads. Its coarse thread design facilitates quick assembly in structural applications, such as heavy machinery, construction frameworks, and marine equipment, where exposure to moisture and chemicals is common. The partially threaded shank concentrates stress away from the head, minimizing the risk of shear failure and enhancing fatigue resistance. With an external hex drive and robust head dimensions, it supports high-torque installation, ensuring secure fastening in industrial fasteners that require reliability and long service life under dynamic conditions.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including a Class 2A thread fit and UNC coarse thread specifications per ASME B18.2.1, ensuring consistent threading and ease of assembly. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental safety, with a right-hand thread direction, 4 1/2" length, and 2 1/2" minimum thread length for versatile application needs.
