This is an industrial heavy-duty American high-strength bow shackle (G-209 screw-pin anchor shackle) with a 5/8" nominal body size and a rated working load limit (WLL) of 3-1/4 tons (3.25 TON / 3250 kg). It combines an efficient threaded screw pin with a hot-dip galvanized body and forged alloy steel red pin—the classic red-and-silver rigging finish. No separate nut or cotter pin is required; the flat pin head allows quick hand or tool installation for frequent connect/disconnect in medium-duty lifting and rigging.
2. Key Features & Design Highlights
- 5/8" body, 3.25T WLL: The bow body is 5/8" (approx. 15.88 mm). The high-strength screw pin is typically one size larger (often 3/4", approx. 19.05 mm) for superior shear and bending strength. Clear body markings include WLL 3 1/4T, 5/8; 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 red pin screws directly into the body. The wide flat head with a small hole allows hand tightening or final torquing with a bar, wire or wrench—ideal for mobile job sites.
- 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.
- Galvanized body with red pin: Hot-dip galvanized silver body resists corrosion in outdoor and port environments. The red screw pin provides high-visibility contrast for quick field inspection.
- 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
- Construction and factory lifting—medium steel structure hoisting, overhead crane work and equipment assembly 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.
- 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.
