M4/M5/M6/M8 304 stainless steel cross flange screws outer hexagonal recess flange bolts toothed screws for Equipment Assembly

Our 304 Stainless Steel Cross Flange Screws (Outer Hexagonal Recess Flange Bolts, Toothed Screws) are professional-grade fasteners engineered for industrial, mechanical, and equipment assembly applications that demand strong, secure, and corrosion-resistant fastening. Crafted from premium 304 stainless steel, these screws deliver exceptional corrosion resistance, rust resistance, and durability, making them ideal for both indoor and outdoor use—even in humid or mild chemical environments—ensuring long-lasting performance and reliable holding power.

 

Featuring a cross (Phillips) drive with an outer hexagonal recess, these flange screws offer dual usability: they can be tightened with either a Phillips screwdriver or a hex wrench, providing flexibility for different installation scenarios and reducing the risk of tool slippage. The integrated flange design acts as a built-in washer, distributing pressure evenly across the surface to prevent damage to materials and enhance stability, while the toothed flange adds extra grip to prevent loosening under vibration or high-load conditions.

 

Designed for versatility and professional use, these screws eliminate the need for additional washers, saving time and effort during installation. Available in popular industrial sizes M4, M5, M6, and M8, they cover a wide range of applications, including machinery assembly, equipment maintenance, mechanical installation, metal fabrication, and industrial hardware projects.

 

Suitable for contractors, maintenance teams, machinery manufacturers, and wholesale buyers, these 304 stainless steel flange screws combine precision engineering, premium material quality, and user-friendly design. They are built to withstand heavy use and harsh industrial environments, making them a trusted choice for any professional fastening application that requires strength, corrosion resistance, and long-term reliability.
