DIN5686 Weldless Knotted Double Loop Chain 

"Knotted Chain"-Engineered Simplicity Meets Utility
Under DIN5686, this chain type is also commonly referred to in American-standard contexts. It's machine-woven with a distinctive "knotted" construction, forming two identical loops securely joined at the center-no welding involved. These loops deliver excellent flexibility and torsional stability, making it ideal for everyday utility tasks.

      Material & Manufacturing

• Weldless Construction: Fabricated without welding, resulting in high flexibility and stress resilience.

• Materials: Commonly made from low-carbon steel or alloy steel, and also available in stainless steel (304/316).

• Finishes: Offered with self-color, zinc-plated, hot-dip galvanized, or polycoated treatments to resist corrosion.

  Sizes & Strength Specs

• Typically available in diameters ranging from 1.4mm to 5.0mm. A sample spec chart shows:

• 1.4mm wire diameter → inner loop length ≈ 21mm, width ≈6.5mm, break load ≈16kg

• Larger sizes scale accordingly, supporting up to ~190kg break load for 5.0mm versions.
