Key Features & Benefits at a Glance
- Superior corrosion resistance from Black-Oxide 18-8 Stainless Steel, ideal for harsh environments and long-term reliability
- High tensile strength of 70,000 psi ensures dependable load-bearing capacity and prevents fastener failure under stress
- Rockwell B70 hardness provides excellent durability and resistance to wear during installation and use
- Class 2A thread fit offers consistent, reliable engagement with standard nuts and tapped holes, reducing assembly issues
- Fully threaded design maximizes grip and holding power across the entire 1-1/4" length for secure fastening
- No. 3 Phillips drive allows for efficient installation with common tools, minimizing slippage and driver cam-out
- Pan head profile combines a low-profile, rounded design with good bearing surface for flush or slightly raised applications
Professional Applications & Engineering Value
These 12-24 UNC coarse thread screws with a pan head and Phillips drive are engineered to address common industrial fastening challenges, such as vibration loosening and environmental degradation. The Black-Oxide coating on 18-8 Stainless Steel significantly enhances corrosion resistance, making them suitable for outdoor equipment, marine components, and chemical processing machinery where moisture and corrosive agents are present. The coarse UNC threading ensures quick assembly and strong holding power in a variety of materials, reducing the risk of cross-threading. With a tensile strength of 70,000 psi, they provide reliable performance in high-stress applications, from machinery assembly to structural frameworks, ensuring long-term operational integrity and reduced maintenance needs.
