• High tensile strength of 70,000 psi ensures reliable performance under heavy loads, preventing fastener failure in demanding applications.
• Fine UNF threads with Class 2A fit provide precise engagement and vibration resistance, maintaining secure connections over time.
• Full threading along the 1/2" length offers maximum grip and adjustability, suitable for varied material thicknesses.
• Rockwell B70 hardness delivers excellent durability and wear resistance, extending the screw's service life.
• Easy installation with Phillips No. 2 drive, allowing for efficient assembly without specialized tools.

Professional Applications & Engineering Value

This 10-32 UNF fine thread screw with a rounded truss head is engineered to address common industrial challenges such as loosening under vibration and corrosion in exposed settings. Made from Black-Oxide 18-8 Stainless Steel, it provides a robust barrier against moisture and chemicals, reducing maintenance costs in applications like electrical enclosures, machinery assembly, and automotive components. The fine thread and Class 2A fit ensure tight tolerances, preventing back-off in dynamic environments, while the wide head distributes clamping force evenly, protecting softer materials from indentation. Ideal for industrial fastening where reliability and compliance with strict standards are critical, this screw offers long-term value by minimizing downtime and enhancing safety.

Specification Summary & Compliance
