Description
Heavy-Duty GB96.2 Carbon Steel Fender Washers | Class 4.8 Galvanized Surface
Product Overview
GB 96.2 Class 4.8 Carbon Steel Large Outer Diameter Flat Washers are engineered to distribute fastener loads across a larger surface area, minimizing stress concentration and preventing deformation on thin-sheet metal, soft materials, or oversized bolt holes.
Manufactured from high-quality low-carbon steel with protective bright zinc plating, these fender washers deliver consistent dimensional accuracy, excellent corrosion resistance, and reliable structural support for machinery, construction, and automotive applications.
Key Features & Advantages
  • Large Load-Bearing Surface: Designed per GB 96.2 standards, the expanded outer diameter (OD) distributes tightening torque evenly, protecting workpieces from surface damage.
  • Reliable Class 4.8 Strength: Processed to strict mechanical property standards with optimized ductility and moderate tensile strength for non-critical structural fastening.
  • Corrosion-Resistant Zinc Finish: Electro-galvanized coating provides protection against moisture, oxidation, and rust in indoor and general industrial environments.
  • Precision Stamping & Smooth Edges: Advanced stamping technology ensures uniform thickness, flat surfaces, and minimal burrs for seamless assembly line integration.

Applications & Industry Uses
GB 96.2 large series flat washers are widely applied in scenarios requiring enhanced load distribution:
  • Sheet Metal Assembly: Prevents pull-through on soft or thin steel panels
  • Timber & Structural Joints: Spreads pressure on wood or softer composite substrates to reduce crushing
  • Automotive & Industrial Machinery: Buffers vibration and maintains joint stability over extended operation
  • General Hardware & Infrastructure: Used in steel framing, enclosures, and electrical rack mountings
Quality Control & Manufacturing Standards
Every batch of GB 96.2 carbon steel washers undergoes rigorous quality inspections to ensure full compliance with international buyer expectations:
  • Dimensional Testing: Caliper and gauge verification of inner diameter (ID), outer diameter (OD), and thickness
  • Plating Thickness Check: Magnetic thickness testing for uniform zinc layer coverage
  • Mechanical & Surface Inspection: Visual burr detection and load tolerance testing before packaging
Packaging & Logistics Options
  • Standard Export Packaging: Bulk in 20/25 kg cartons + fumigated wooden pallets
  • Small Box Packaging: Customized polybags or small inner boxes with custom barcode labeling
  • Port of Loading: Ningbo / Shanghai / Lianyungang, China
  • Trade Terms: FOB, CFR, CIF, DDP, DAP
Frequently Asked Questions (FAQ)
Q1: What is the main difference between GB 96.2 and standard GB 97.1 flat washers?
A: GB 96.2 features a significantly larger outer diameter (approximately 3× the nominal thread diameter), making it ideal for soft materials, elongated holes, or high-torque load distribution compared to standard GB 97.1 washers.
Q2: Can you provide customized salt spray testing for higher corrosion protection?
A: Yes, we can offer thicker electro-zinc coatings or passivation processes (such as yellow zinc or ROHS-compliant trivalent chromium) to meet specific salt spray resistance requirements (e.g., 48h to 96h).
Q3: Are samples available before placing a bulk order?
A: Yes, standard size samples are provided free of charge for quality verification and fit testing. Shipping fees apply.
