Description
When you’re working on hydraulic systems, every connection matters. This isn’t just any bolt—it’s a precision-made DIN933 hex head bolt built to handle the pressures and vibrations that come with hydraulic applications. Whether you’re rebuilding a bonnet assembly or replacing worn hardware, this bolt gives you the strength and reliability you need to keep your system sealed and working right.
What You’re Getting
- Grade 8.8 tensile strength that won’t stretch or fail under hydraulic pressure
- Precision UNF threads for a tight, secure connection that stays put
- DIN933 specification ensures consistent quality and proper fit
- Corrosion-resistant finish that holds up to hydraulic fluid and weather
Built for Real Farm Work
This bolt is specifically designed for hydraulic bonnet kits and similar high-pressure applications. You’ll find it in hydraulic cylinders, valve assemblies, and pump housings where a reliable connection is critical. It’s the kind of hardware that keeps your hydraulics running when there’s hay to bale or fields to work.
Made to Last
The 8.8 tensile rating means this bolt can handle serious stress without stretching or breaking. That’s important when you’re dealing with hydraulic pressures that can exceed 2,000 PSI. The precision manufacturing ensures clean threads that won’t strip or cross-thread during installation.
Installation Notes
Use the proper torque specification for your application—over-tightening can damage threads or distort sealing surfaces. A drop of thread locker helps prevent loosening from vibration, and a thin coat of anti-seize compound makes future removal much easier.
