The numbers refer to the pressure class (150 psi vs 600 psi) and corresponding bolt strength. 16 150 flange bolts are typically ASTM A193 Grade B7 for moderate-pressure applications. 16 600 flange bolts use higher-grade materials like B16 or L7 for high-pressure, high-temperature service. The 16 bolt flange pattern is common to both classes but with different bolt diameters and lengths.
