Product Description

GB 96.2 Class 4.8 Zinc Plated Carbon Steel Large Outer Diameter Flat Washers

GB 96.2 Class 4.8 Carbon Steel Large Outer Diameter Flat Washers are specifically designed to distribute fastener loads over a larger surface area, reducing stress concentration and preventing deformation on thin-sheet metal, soft materials, or oversized bolt holes. Manufactured from high-quality low-carbon steel and finished with a protective bright zinc plating, these fender washers offer 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, shielding target workpieces from surface damage.
Reliable Class 4.8 Strength: Processed to strict mechanical property standards, offering optimized ductility and moderate tensile strength ideal for non-critical structural fastening.
Corrosion-Resistant Zinc Finish: Electro-galvanized (zinc plated) coating guards against moisture, oxidation, and early rusting 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.
