AI Mode conversation: STAINLESS STEEL 316 UNC BUTTON HEAD SOCKETYou said: STAINLESS STEEL 316 UNC BUTTON HEAD SOCKETStainless Steel 316 UNC Button Head Socket Screws are premium, marine-grade fasteners designed with a unified coarse thread for high-corrosion environments. They feature a low-profile, rounded dome head with an internal hexagonal (Allen) drive. This combination yields a clean visual finish while protecting moving parts or fabrics from snagging.
Core Technical Specifications
- Material Grade: 316 (A4) Stainless Steel. It contains molybdenum, offering superior resistance against chlorides, salt water, coastal conditions, and harsh chemicals compared to standard 304 grade.
- Thread Type: UNC (Unified National Coarse). This is an imperial (inch-based) pitch standard commonly used across American assemblies, heavy industrial machinery, and automotive components.
- Standards Compliance: Typically manufactured to ANSI B18.3 standards for imperial specifications.
- Torque Profile: Because the dome design features a shallower drive recess and thinner wall thickness, button heads possess about 70% to 80% of the installation torque rating compared to standard cylindrical socket cap screws. They are ideal for moderate-load or decorative clamping rather than structural, high-clamp joints.
