GI Washer 10mm – Galvanized Iron Flat Washer for Strong, Rust-Resistant Fastening

The GI Washer 10mm is a high-strength, corrosion-resistant flat washer made from galvanized iron (GI), designed for use with 10mm bolts, screws, and threaded rods. Its primary function is to distribute the load of a fastener evenly across a surface, minimizing surface deformation, preventing pull-through, and improving joint strength in both temporary and permanent assemblies.

Galvanization provides a protective zinc coating that shields the washer from rust, moisture, and environmental wear, making it ideal for outdoor, industrial, and heavy-duty applications. Its standard size, compatibility with a wide range of materials, and long-lasting performance make it a staple in construction, electrical installations, and mechanical assemblies.

Specifications:

• Material: Galvanized Iron (GI)

• Inner Diameter: 10mm (fits M10 bolts/screws)

• Outer Diameter: Typically 20–24mm (varies by standard)

• Thickness: ~1.5–2.5mm (varies by usage)

• Coating: Zinc galvanized (for corrosion resistance)

• Type: Flat washer (plain)

Key Features:

• ✅ Rust-Resistant: Zinc coating resists corrosion in humid or outdoor environments

• ✅ Load Distribution: Spreads pressure from fasteners to prevent surface damage or cracking

• ✅ Improved Fastening Stability: Reduces loosening due to vibration or torque

• ✅ Versatile Use: Fits standard M10 fasteners

• ✅ Economical & Durable: Cost-effective for bulk applications with long-lasting performance

Applications:

• Construction: Used in steel frameworks, scaffolding, and mounting structures

• Electrical Panels: Ensures secure, grounded fastenings for busbars and components

• Plumbing & Piping: Secures flanges and fixtures

• Mechanical Assemblies: Balances load across moving or vibrating parts

• DIY & Home Repair: For shelving, mounts, furniture, and more

Conclusion:

Whether you’re fastening metal joints, supporting heavy hardware, or ensuring secure electrical or mechanical connections, the 10mm GI Washer provides reliable load distribution, corrosion resistance, and fastening integrity. It’s an essential component in any toolbox or industrial kit.
