Wire Rope Thimble – Type A

Key Characteristics of Type A Thimbles

Unlike heavy-duty (Type B) thimbles, Type A variants are typically lighter with thinner walls and a more rounded, open shape.

• Standards and Specifications: Common standards include DIN 6899 Form A (German style) and JIS B-2802 Type A (Japanese style).
• Materials: Usually manufactured from mild steel or high-tensile carbon steel. They are often available in 304 or 316 stainless steel for superior corrosion resistance in marine environments.
• Finish: Common finishes include electro-galvanized (zinc-plated), hot-dip galvanized (HDG), or self-colored. HDG offers a thicker, more durable coating for outdoor use.
• Size Range: They are available in a broad range of sizes, typically from 2mm to over 28mm to match specific wire rope diameters.
