Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide steel coating, ideal for industrial environments requiring durability.
- Superior tensile strength of 180,000 psi ensures reliable performance under high-stress conditions.
- Integrated flange design eliminates the need for separate washers, speeding up assembly and reducing parts count.
- External hex drive allows for easy installation with standard tools, minimizing slippage and tool wear.
- Coarse UNC threading provides quick engagement and strong holding power in various materials.
- Class 2A thread fit ensures consistent, precise fastening with standard mating components.
- Partially threaded shank offers optimal clamp load distribution, reducing the risk of joint loosening.
Professional Applications & Engineering Value
This 3/8"-16 UNC hex head screw is engineered to address common industrial challenges such as vibration-induced loosening and corrosion in demanding applications. Constructed from black-oxide steel with a Rockwell C38 hardness, it provides excellent wear resistance and longevity in harsh environments like machinery assembly, automotive frameworks, and construction projects. The flanged design distributes pressure evenly, preventing surface damage and enhancing joint integrity, while the coarse thread and partial threading ensure rapid installation and secure fastening in metal, wood, and composite materials. Ideal for heavy-duty fastening, it reduces maintenance needs and downtime, delivering consistent performance in critical B2B settings.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for precise dimensional accuracy and compatibility. It meets common industry specifications for inch fasteners, including material and threading guidelines, and is manufactured to ensure reliability in tensile and hardness metrics. Compliant with general industrial standards, it supports applications requiring robust, corrosion-resistant components without specific RoHS or REACH declarations unless otherwise specified.
