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
Technical Specifications
Dimension Core Requirements Selection & Processing Points
Material & Corrosion Resistance Food-grade corrosion resistance 316L stainless steel (chloride-ion pitting resistance), 304 for general applications, 904L for highly corrosive conditions
Structure & Precision Reliable sealing, easy assembly Hexagonal shape, thread precision 6H/5H, anti-gall design with flat washers/locking parts
Hygiene & Compliance No residue, easy to clean Surface roughness Ra ≤ 0.8 μm, compliant with FDA/GB 4806 food contact standards
Mechanical Properties Vibration resistance, pressure resistance Property class A2-70 (tensile strength ≥ 700 MPa), thick or locking nuts for high-vibration applications
Standard & Compatibility Interchangeability, compatibility GB/T 6170 (Type 1), GB/T 6175 (Type 2), sizes M6-M24
Processing & Application Guidelines
  • Processing Control: Precision thread turning, deburring, heat treatment to prevent hydrogen embrittlement
  • Installation Specification: Clean threads, diagonal step-by-step tightening, specified torque application
  • Maintenance & Corrosion Protection: Regular inspection, timely replacement, passivation for high-humidity environments
Selection Guide
  • Small/Household Dispensing Equipment: 304 stainless steel A2-70, GB/T 6170, M6-M12 with EPDM gaskets
  • Commercial Brewing/High-Pressure Pipeline: 316L stainless steel A2-70/A4-80, GB/T 6175, M10-M20 locking design
  • High Corrosion/Frequent Cleaning: 316L or 904L, Ra ≤ 0.8 μm, electropolished, EHEDG/3A compliant
