- Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments.
- Superior thread reliability with Class 3A fit, ensuring precise, vibration-resistant connections in critical assemblies.
- Enhanced durability and surface protection from the passivated finish, extending service life by preventing oxidation.
- High tensile strength of 70,000 psi and Rockwell B70 hardness for dependable performance under heavy loads.
- Easy installation and removal with the 1/8" hex drive, providing secure tool engagement and reducing strip-out risks.
- Integrated flange design distributes clamping force evenly, eliminating the need for a separate washer and speeding up assembly.
- Full threading along the 1" length offers maximum grip and adjustability in a wide range of material thicknesses.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 10-24 UNC rounded head screws in 316 stainless steel address common failure points in corrosive or high-stress applications. The passivated finish significantly enhances the material's innate resistance to chlorides and acids, making these flange screws a top choice for chemical processing equipment, marine hardware, and food-grade machinery where sanitation and durability are paramount. The coarse UNC thread and Class 3A thread fit provide a secure, tight connection that resists loosening from vibration, a critical feature in automotive or heavy machinery assembly. The combination of a wide button head and integrated flange offers a large bearing surface, preventing surface damage and ensuring a reliable, leak-proof seal in piping or enclosure systems.
Specification Summary & Compliance
This screw adheres to the Unified National Coarse (UNC) thread standard with a precision Class 3A thread fit for superior dimensional accuracy. Manufacturing and material composition are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they are free of restricted hazardous substances and safe for use in global industrial markets.
