Are there any recommendations for additional stamping on Green Pin^® Shackles?

Note: Main dimensions, general info and warnings can be found in our latest catalogue.

If the recommendations in this product information are followed performance of the shackles is guaranteed:

• permanent identification marks, or symbols, are to be made by dot peen marking or with stamps having rounded profiles (low stress stamps).
• the number of marks on a shackle is to be kept to the minimum.
• the use of fractions and oblique strokes is to be avoided and a dot or hyphen is preferable to a dividing line.
• values of WLL are, generally, to be marked to one place of decimals (except for 0.25 and 0.75) up to 100 t and in integers thereafter. The word “tonnes” may be abbreviated to “t”.
• recommended sizes of marks are
  • Diameter of part to be marked > recommended size of mark
  • less then 12.5 mm > 3.0 mm
  • 12.5 to 26 mm > 4.5 mm
  • over 26 mm > 6.0 mm

Typical arrangements of marks can be found in the following illustrations.
