Product Description
Black Zinc Plated Hexagonal Nuts for Draft Beer Mechanical Parts
Precision CNC machined hex nuts specifically designed for brewing and dispensing equipment, featuring black zinc plating for enhanced corrosion resistance and professional appearance.
Applications in Beer Machine Components
Machined hex nuts serve as core connecting components in beer machines, providing structural fastening, sealing assurance, and positioning installation while balancing strength, hygiene, and corrosion resistance.
- Tap/Dispense Tower Assembly: Fixes tap to tower and adjusts outlet direction with gaskets for sealing
- Pipeline and Valve System: Fastens sanitary pipe flanges and valve bodies, withstands beer pressure and vibration
- Tank and Frame: Secures nozzles, legs, and internal components of fermentation tanks
- Coupler and Gas Circuit: Locks CO₂ inlet nozzles and beer check valves, prevents gas leakage
