Specifications and models
Our 8.8 Grade Galvanized Outer Hexagon Screws—available in full tooth and half tooth designs—are professional high-strength fasteners engineered for industrial, construction, and mechanical applications that require reliable load-bearing and corrosion resistance. Crafted to meet 8.8 grade standards, these hexagon head bolts deliver exceptional tensile strength and durability, making them ideal for securing heavy components, machinery parts, and structural elements in high-stress environments.
 
The galvanized finish provides superior corrosion resistance and rust protection, ensuring long-lasting performance both indoors and outdoors, even in damp or harsh working conditions—perfect for construction sites, industrial facilities, and mechanical installations. Featuring an outer hexagon head design, these screws allow for easy, secure tightening with standard hex wrenches, reducing slippage and ensuring efficient installation, whether for professional contractors or maintenance teams.
 
Available in two tooth options (full tooth and half tooth) to suit different fastening needs: full tooth screws offer maximum grip and stability for applications requiring strong holding power, while half tooth designs balance grip with easier installation in thicker materials. The popular M4 and M5 sizes cover a wide range of professional uses, including machinery assembly, equipment maintenance, construction brackets, metal fabrication, and structural fastening.
 
Designed for versatility and reliability, these 8.8 grade galvanized outer hex screws are suitable for industrial projects, construction jobs, mechanical repair, and wholesale orders. Every piece is precision-manufactured to ensure consistent size, thread quality, and strength, delivering a trusted fastening solution that stands up to heavy use and harsh conditions—ideal for professionals seeking high-performance, long-lasting fasteners.
