Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in harsh industrial environments.
- High torque transmission via the external hex head design, allowing for secure fastening with standard tools and reducing slippage.
- Reliable thread forming action that creates strong, permanent threads in materials like steel and aluminum without pre-tapping, saving installation time.
- Enhanced load distribution from the integrated flange (0.676" diameter), minimizing surface damage and providing a wider bearing area.
- Versatile coarse UNC threading for quick assembly and excellent grip in various substrates, including sheet metal and cast iron.
- Full threading and blunt tip design for consistent holding power along the entire 3/4" length and easy alignment during insertion.
- Compliance with RoHS 3 and REACH regulations, ensuring safe, eco-friendly use in global industrial supply chains.
Professional Applications & Engineering Value
This 5/16"-18 UNC zinc-plated steel tapping screw is engineered to address common fastening challenges in industrial settings. The thread forming design eliminates the need for separate tapping operations, reducing labor costs and preventing thread stripping in steel, aluminum, brass, cast iron, and sheet metal. Its coarse thread spacing and external hex drive enable rapid installation with high torque resistance, ideal for assembly lines and heavy-duty equipment. The flanged head distributes clamping force evenly, protecting soft materials from deformation. Made from robust zinc-plated steel, it offers reliable performance in corrosive environments, while full threading ensures maximum pull-out strength for critical joints.
Specification Summary & Compliance
This screw features UNC coarse threads with standard Class 2A fit for consistent engagement. Key dimensions include a 5/16"-18 thread size, 3/4" length, and 1/2" hex head width. It is manufactured to industry standards for thread forming tapping screws and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements in industrial applications.
