Product Introduction
Our Heavy-Duty Flat Jaw Locking Pliers (W29036 – W29037 Series) are engineered for heavy-duty metal fabrication, sheet metal processing, and industrial clamping tasks. Stamped from high-strength alloy steel, the body provides maximum structural rigidity. The drop-forged alloy steel jaws undergo whole-tool heat treatment to deliver superior toughness and tooth wear resistance. The flat jaw profile maximizes contact area on flat plates, square bars, and sheet metal, distributing 1135 kg of clamping force evenly. Equipped with a knurled adjustment bolt for precise jaw setup and a guarded safety release lever (anti-pinch design) that absorbs spring snap-back during unlocking. Available in 180mm (7″) and 220mm (10″) standard sizes.
Product Features

FAQ
Q1: What are flat jaw locking pliers best used for?
A1: Flat jaw locking pliers excel at holding, clamping, and pressing flat metal plates, sheet metals, square stock, and straight brackets where maximum surface area contact is needed.
Q2: What is the maximum clamping force for W29036 and W29037?
A2: Both models W29036 (7″) and W29037 (10″) deliver a heavy-duty rated maximum clamping force of 1135 kg.
Q3: How does the guarded safety release lever (anti-pinch design) work?
A3: The guarded release lever buffers the spring tension when disengaging the lock, controlling the handle movement to prevent it from snapping back and pinching your palm.
Q4: How do I adjust the jaw opening and locking pressure?
A4: Simply turn the knurled screw at the base of the handle clockwise to narrow the opening and increase clamping force, or counter-clockwise to enlarge the jaw opening.
Q5: Do you support custom OEM branding and personalized packaging?
A5: Yes, we provide full OEM/ODM services including laser logo etching on the tool body, custom handle coatings, and personalized blister card or color box packaging.
