Sany A210111000321 Bolt
1 、 High strength and stability
The product is made of alloy steel with increased hardness (HRC 35-40), which ensures static loads of up to 1,500 N · m and corrosion resistance due to the anti-corrosion coating (zinc).
Flexibility of installation and maintainability
2 、 Simplified hexagonal head and standard M12x30 thread (compliance with ISO 4014) allow you to use a bolt for connecting metal, wood and plastic. It is easy to adjust and replace in case of wear.
3 、 Compatibility and certification
Meets the standards of DIN 933 and ISO 898-1, which guarantees compatibility with Sany and other brands. Deep testing for strength and tightness was carried out.
