This is an industrial heavy-duty American high-strength bow shackle (G-209 screw-pin anchor shackle) with a 3/4" nominal body size and a rated working load limit (WLL) of 4-3/4 tons (4.75 TON / 4750 kg). One of the most widely used shackle designs in global industry, the G-209 uses a convenient threaded screw pin for quick hand or tool installation without nuts or cotter pins. It is ideal for frequent connect/disconnect, temporary lifting and fast rigging changeovers in medium to heavy-duty applications.
2. Key Features & Design Highlights
- 3/4" body, 4.75T WLL: The bow body is 3/4" (approx. 19.05 mm). The high-strength screw pin is typically one size larger (often 7/8", approx. 22.2 mm) for superior shear and bending strength. Clear body markings include WLL 4 3/4T, 3/4; CE marking can be arranged per order when required by your market. Breaking load typically reaches 4× or 6× WLL depending on manufacturing standard.
- Fast screw-pin connection: Precision male thread on the pin screws directly into the body. The wide flat head with a small hole allows hand tightening or final torquing with a bar or wrench—very efficient for field assembly and removal.
- Wide bow (anchor) design: Wider internal space than chain (Dee) shackles—accepts multiple slings, hooks or links and allows angular movement, reducing eccentric stress concentration.
- Full hot-dip galvanizing: Body and screw pin are hot-dip galvanized for a dense silver zinc layer with excellent weather and wear resistance—resisting rust and thread seizure in outdoor, port and mining environments.
- Forged alloy steel: Drop-forged from high-strength alloy steel, quenched and tempered. Excellent fatigue and low-temperature toughness; under overload the steel tends to deform rather than snap brittle.
3. Primary Applications
- Factory and mobile crane lifting—everyday hoisting, assembly and turnover of medium and large equipment where frequent disconnection is required.
- Port and logistics handling—rapid change of slings and fittings during cargo loading and unloading.
- Vehicle recovery and temporary towing—quick attachment of tow lines to front/rear recovery points on trucks and off-road vehicles.
- Steel structure alignment—temporary tensioning and positioning during erection of frames, curtain walls and bridge trusses with come-alongs and turnbuckles.

Safety Guidelines
- Do not use in long-term fixed systems with continuous vibration or rope rotation—use a G-2130 bolt-nut-cotter pin shackle instead.
- Confirm the pin is fully screwed in and the flat head is flush with the body before loading—never lift with the pin only partially engaged.
- Do not weld, heat or modify—the heat treatment must not be altered.
