Question 1

What is a dee shackle (D shackle)?

Accepted Answer

A dee shackle — also called a D shackle or chain shackle — has a narrow, straight-sided bow shaped like the letter D. The load travels in a straight line through the pin, making it ideal for single in-line connections such as chain-to-hook, sling eye-to-padeye, or a single-leg rigging assembly. It is not designed for multi-leg or side-loaded connections.

Question 2

Dee shackle vs bow shackle — which should I use?

Accepted Answer

Use a dee shackle when the load stays in-line and only one fitting connects to the pin — typical for chain blocks, single-leg pulls and towing. Choose a bow shackle when multiple sling legs share one pin or the load may angle — the wider bow reduces pin crowding and side-loading risk. When in doubt for multi-leg lifts, use a bow shackle.

Question 3

What is WLL on a forged dee shackle?

Accepted Answer

WLL (working load limit) is the maximum load the shackle is rated to carry in normal service. It is stamped on the shackle body and must remain legible before every lift. Never exceed the stamped WLL — proof load is typically about 2× WLL and minimum break load about 6× WLL on commercial forged shackles, giving a built-in safety margin when used correctly.

Question 4

Screw pin vs bolt-type dee shackle — what is the difference?

Accepted Answer

Screw pin dee shackles use a threaded pin you hand-tighten — quick to fit for temporary rigging, chain blocks and site lifts. Bolt-type (nut-and-bolt) shackles add a secure nut and often a cotter pin for semi-permanent connections where vibration could loosen a screw pin. Our catalogue focuses on screw pin type for everyday industrial rigging; ask us for bolt-type equivalents on bulk enquiries.

Question 5

What standard applies to forged dee shackles in India?

Accepted Answer

Industrial forged shackles in India are commonly specified to BIS-aligned requirements such as IS 4696 for general-purpose shackles, with grade 80 alloy steel construction, proof testing and permanent WLL marking. Match shackle grade to your chain and sling assembly — a grade 80 dee shackle pairs correctly with grade 80 chain and fittings.

Question 6

Can a dee shackle take side load or angled pull?

Accepted Answer

No — side loading a dee shackle can twist the body and cut effective capacity dramatically, sometimes by half or more. Dee shackles are strictly for in-line tension. If the load direction may change or multiple legs connect to one pin, use a bow shackle instead and apply any required angularity reduction factors.

Question 7

What is the HSN code and GST rate for dee shackles?

Accepted Answer

Forged iron and steel shackles are commonly invoiced under HSN 7326 (other articles of iron or steel) at 18% GST, though classification can vary by exact specification. We issue GST-compliant invoices on every order — share your GSTIN on checkout or enquiry for procurement records.
