Black oxide finish gives a professional appearance for visible fastener assemblies. Covers M2 to M24 for all standard metric applications.

Key Specifications

Why Choose Grade 8.8 Black Lock Washers?

• Grade 8.8 high strength — higher spring force than standard grade; stronger anti-loosening resistance
• Black oxide finish — professional appearance for visible fastener assemblies; light corrosion resistance
• DIN127 standard — interchangeable with GB93 and ISO 7980
• M2–M24 range — covers all standard metric sizes from electronics to heavy structural assembly
• Cost-effective — carbon steel provides high strength at lower cost than stainless steel

Typical Applications

• Motor and gearbox mounting in machinery
• Structural steel assembly requiring vibration resistance
• Automotive and industrial equipment fastening
• 3D printer and CNC machine frame assembly
• Electronics enclosure panel fastening (black finish for aesthetics)
• General mechanical assembly in dry indoor environments

FAQ

Q: What is the difference between grade 8.8 and standard spring lock washers?
A: Grade 8.8 lock washers have higher tensile strength and spring force than standard (grade 4.8) lock washers. They provide stronger anti-loosening resistance and are recommended for use with grade 8.8 or higher bolts.

Q: Is black oxide corrosion-resistant?
A: Black oxide provides light corrosion resistance suitable for dry indoor environments. For outdoor or humid applications, use A2-70 304 stainless steel lock washers instead.
