Product Introduction
Our Sheet Metal Locking Pliers (Duckbill Clamps) are engineered specifically for metal bending, sheet alignment, welding clamp-ups, and HVAC duct fabrication. The extra-wide, flat parallel jaws distribute a powerful 454kg clamping force evenly over broad surfaces, ensuring a rock-solid lock while preventing localized sheet metal denting or distortion. Forged alloy steel jaws combined with a high-tensile stamped steel handle and whole-body heat treatment make this tool an indispensable heavy-duty solution for metalworkers and automotive technicians.
Product Features
- Wide Flat Jaw Design: Tailored for gripping, forming, bending, and holding sheet metal, iron plates, and flat panels cleanly.
- Forged Alloy Steel Jaws: Premium alloy steel forged jaws with whole-body heat treatment for superior structural hardness and long-term durability.
- Heavy-Duty Stamped Steel Body: Precision-stamped from high-tensile alloy steel plate to prevent flexing under intense clamping loads.
- 454kg Massive Clamping Force: Delivers a heavy-duty 454kg locking pressure distributed evenly over broad sheet metal surfaces.
- Precision Tail Screw Adjustment: Threaded screw mechanism allows micro-adjustment of jaw opening capacity and locking force.
- Anti-Pinch Safe Release Trigger: Intuitive safe-release lever cushions disengagement, preventing violent snap-backs and protecting hand safety.

FAQ
Q1: What is the difference between sheet metal locking pliers and standard pliers?
A1: Sheet metal locking pliers feature extra-wide, flat duckbill jaws that distribute force across a broad area, ideal for bending and welding metal sheets without leaving deep indentations. Standard pliers have narrower jaws for point or pipe clamping.
Q2: What does “Parallel Max Opening” mean in the specifications table?
A2: It refers to the maximum gap measured when the upper and lower flat jaws remain completely parallel to each other (13mm for 8″, 20mm for 10″), ensuring maximum contact area and gripping stability.
Q3: What is the clamping force capacity of these pliers?
A3: Both the 200mm (W29251) and 250mm (W29252) models deliver a heavy-duty clamping force of up to 454kg.
Q4: What is the “anti-pinch / safe release” design?
A4: The safe release lever (anti-pinch) cushions the disengaging force when unlocking high-pressure clamps, preventing violent snapping that can pinch hands and enabling safe, smooth one-handed release.
Q5: What are the packaging specs and MOQ for bulk orders?
A5: 8″ (W29251) comes 3 pcs/box, 24 pcs/ctn (GW 13.50kg); 10″ (W29252) comes 2 pcs/box, 16 pcs/ctn (GW 12.50kg). Standard stock items have low MOQs, while custom OEM orders start at 1,000 pcs.
