| High Light | ASTM A325 galvanized metal screw ，A307 Gr5 zinc plated screw ，hexagon pan head metal screw | ||
Astm A325 A307 Gr2 Gr5 Astm 193 B7 Zinc Plated Coated Galvanized Cross Recess Hexagon Pan Head Metal Screw
This cross recess hexagon pan head screw conforms to multiple ASTM standards: A325 (high-strength structural bolt), A307 (general-purpose carbon steel bolt), and A193 B7 (alloy steel for high-temperature service) . Strength grades include GR2, GR5, etc. Finishes available: zinc plated, coated, or hot dip galvanized. Hexagon head is the primary drive with cross recess as auxiliary for different tools. The pan head provides a large bearing surface. This multi-standard product suits applications from general structures to high-temperature service. HDG provides 40-70μm zinc layer for long-term outdoor exposure; electroplating is more economical for indoor use; coatings (e.g., Dacromet) offer higher salt spray resistance.
