Description
ASME B18.6.4 Hex Washer Head Tapping Screws are engineered for high-strength fastening applications that require self-tapping capability without pre-drilled or pre-threaded holes. The integrated hex washer head provides a broad load-bearing surface with excellent torque distribution, while also acting as a locking feature to reduce loosening under vibration.
Manufactured from durable carbon steel or corrosion-resistant stainless steel, these tapping screws are available in a wide range of protective finishes such as black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and more—offering tailored performance for both indoor and outdoor use.
These screws conform to ASME B18.6.4 standard and are cross-compatible with multiple international standards including GB, DIN, ISO, ANSI/ASTM, BS, and JIS, ensuring global reliability and interoperability.
