Key Features & Benefits at a Glance
- Exceptional corrosion resistance from 18-8 Stainless Steel and passivated finish, ensuring long-term reliability in harsh environments.
- High tensile strength of 100,000 psi provides secure fastening under significant mechanical stress, reducing the risk of failure.
- Rockwell B100 hardness offers excellent durability and resistance to wear, extending the screw's service life.
- Dual Phillips/Slotted (No. 2) drive allows for flexible installation with common tools, improving assembly efficiency.
- Class 2A thread fit with UNC coarse threading ensures easy, reliable engagement and reduces cross-threading during installation.
- Fully threaded design maximizes grip and load distribution along the entire length for superior holding power.
- Rounded (Pan) head profile provides a low-profile, secure fit that minimizes snagging and enhances safety in dynamic applications.
Professional Applications & Engineering Value
These 8-32 UNC Rounded Head Screws in 18-8 Stainless Steel are engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress fatigue. The passivated finish significantly enhances resistance to oxidation and chemical exposure, making them ideal for use in manufacturing equipment, electrical enclosures, and outdoor machinery. The combination of coarse UNC threading and Class 2A fit ensures quick, accurate installation with standard tools, reducing assembly time and errors. With a 100,000 psi tensile strength and fully threaded design, they provide consistent clamping force and are suitable for applications requiring reliable fastening in demanding environments, from automotive assemblies to structural frameworks.
Specification Summary & Compliance
This screw features precise Class 2A thread fit and UNC coarse thread spacing, manufactured to ASME B18.6.3 standards for dimensional accuracy and performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for global industrial use.
