Screw Pin Chain Shackle

No.701002
A Screw Pin Chain Shackle (also known as a D-Shackle) is a U-shaped connector characterized by its straight sides and a threaded pin. Unlike the rounded "Bow" or "Anchor" shackles, the chain shackle's narrow profile is designed specifically for straight, in-line tension.
  • Shape: The straight "D" shape keeps the load centered on the pin, preventing the twisting or bending that can occur in wider shackles during in-line pulls.
  • The Screw Pin: Features a threaded end that screws directly into one ear of the shackle. This allows for quick connection and disconnection, making it ideal for "pick and place" tasks where rigging is frequently changed.
  • Material: Usually forged from carbon steel (Grade A) or alloy steel (Grade B), often with a hot-dip galvanized finish for corrosion resistance.

Safety Guidelines

Always

  • Store and handle shackles correctly.
  • Inspect shackles before use and before placing into storage.
  • Select the correct pattern of shackle (Dee/Bow) and pin type for the application.
  • Fully tighten the pin before lifting.
  • Ensure the load acts through the centre line of the shackle.
  • Allow for the full resultant imposed load (consider angles).

Never

  • Use shackles with bent pins or deformed bodies.
  • Force, hammer, or wedge shackles into position.
  • Eccentrically load shackles (side loading).
  • Replace the pin with a standard bolt.
  • Fit pins in contact with moving parts which may unscrew them.
  • Shock load shackles.

Selection & Operation Guide

Selecting the Correct Shackle

Type: Use Anchor (Bow) shackles for multi-leg systems or where side loading may occur. Use Chain (Dee) shackles for straight-line pulls.

Pin Type:
Screw Pin: Suitable for general, non-permanent purposes.
Bolt Type (Safety Pin): Essential for long-term installations or where the pin may rotate under load.

⚠️ CAUTION: Loading on the Pin BS and ISO Standard shackles are rated for the pin to accept a central point load. Unless stated otherwise, assume the jaw must be fully filled and the load evenly distributed across the full pin width.

Using Shackles Safely

Avoid Side Loading: Position the shackle so the body takes the load along its center line. Use spacers if necessary to center the load on the pin.

Tightening: Tighten screw pins by hand, then lock with a small bar. Do not overtighten to the point of deforming the body. For bolt types, ensure the split cotter pin is fitted.

Choke Hitches: Place the pin through the eye of the sling. Never place the pin in contact with the "bight" of the choke or moving parts, as friction can unscrew the pin.

Maintenance & Storage

Storage: Store in a clean, dry place protected from corrosion. Never modify or galvanize a shackle without supplier approval.

Inspection: Check regularly for: distorted/stretched bodies, bent pins, damaged threads, nicks, gouges, or corrosion. illegible markings. If any defect is found, refer to a Competent Person.
