Safety Chain & Fittings for Swing Applications
When it comes to swing chains, safety and reliability are non-negotiable. At Boyuan Metal, we supply DIN766 swing chains with matching H-type and Y-type eye nuts, designed specifically for playground and recreational swing applications.
DIN766 Swing Chain
The most commonly used chain standards for swings are DIN766 5mm and 6mm, with the following key features:
Specification | Details |
|---|---|
Standard | DIN766 |
Diameter | 5mm or 6mm |
Grade | Grade 30 (G30), tested for load-bearing capacity |
Inside Width Tolerance | Tightly controlled to prevent child finger entrapment |
Surface Finish | Hot-dip galvanized or electro-galvanized for outdoor corrosion resistance |
The inside width of the links is manufactured to a precise tolerance — neither too wide nor too narrow. This is a critical safety feature designed to prevent children's fingers from getting caught during use, in compliance with European playground safety standard EN 1176.
Despite being a lightweight chain, Grade 30 ensures the chain provides reliable load-bearing capacity, making it suitable for the dynamic forces generated during swinging.

Choosing Between Galvanized and Stainless
For outdoor swings, both finishes work: hot dip galvanized chain is the economical choice, while SUS304 or AISI316 stainless steel keeps its look in coastal air and requires less maintenance. Our DIN 766 swing chains are available in both, in 5 mm, 5.5 mm and 6 mm.
Matching Eye Nuts and Hardware
The chain is only half the assembly - the H-type and Y-type eye nuts are what connect it to the swing frame, and we supply both types with matching DIN 766 stainless steel swing chain. Tell us the swing model and the fixing you need and we will supply the set.
Frequently Asked Questions
What diameter should a garden swing chain be?
The most common swing chains are DIN 766 in 5 mm and 6 mm, as covered in the table above. Tell us the swing model and user weight range and we will confirm the diameter.
Stainless or galvanized for an outdoor swing?
Both work outdoors: hot dip galvanized is the economical choice, stainless steel needs less maintenance and keeps its look in coastal air. Both are available in the sizes above.
Do you also supply the eye nuts?
Yes - H-type and Y-type swing eye nuts are made to match the chain, and we supply them together with the chain as one set.
