Frequently Asked Questions

• Q: Can I use Grade 8 nuts with lower-grade bolts?
  A: It's recommended to use Grade 8 nuts with Grade 8 bolts to maintain the integrity and strength of the assembly.
• Q: What torque should I apply when installing these nuts?
  A: Follow the recommended torque specifications for Grade 8 fasteners based on the bolt size and application.
• Q: Are these nuts suitable for outdoor use?
  A: The zinc yellow plating provides some corrosion resistance, but for highly corrosive environments, consider using nuts with enhanced corrosion protection.
• Q: Are these nuts RoHS compliant?
  A: The zinc yellow plating contains hexavalent chromium (Cr+6), which is restricted under RoHS regulations. If RoHS compliance is required, please consider alternative products with compliant finishes.
