*Note: The "3-14"" in the original data is assumed to be a typo and corrected to "3-1/4"" for rationality, consistent with the product's size logic.

Max. Opening: The maximum distance between the clamp's upper and lower jaws, determining the thickness/width of workpieces it can accommodate.
Throat Depth: The vertical distance from the jaw face to the inner edge of the clamp's "C" frame, which limits how far a workpiece can extend into the clamp.
Load Limit: The maximum weight the clamp can securely hold without structural deformation or slippage.

Material & Structural Advantages

Ductile Iron Frame: Constructed with high-quality ductile iron, a material that combines the strength of steel with the flexibility of iron. This ensures the clamp's frame resists bending or cracking under heavy loads.
Dual Corrosion-Resistant Finishes: Available with two surface treatments:
- Black oxide finish: Offers excellent wear resistance and a sleek, industrial look, ideal for dry workshop environments.
- Zinc-plated finish: Provides superior protection against moisture and rust, perfect for humid or semi-outdoor use.
Precision-Threaded Screw: Features fine, evenly cut threads that enable smooth, consistent tightening and loosening, reducing friction and preventing jamming.
Ergonomic Handle: Designed for a comfortable, non-slip grip, allowing users to apply torque easily without hand fatigue.

Quality Assurance

All clamps undergo load testing to confirm they meet stated load limits before leaving the factory.
Ductile iron frame undergoes heat treatment to enhance hardness and impact resistance.
Reinforced connection between handle and screw prevents detachment, extending product service life.

Application Scenarios

General Woodworking Workshops: Essential for securing wooden boards, panels, or furniture components during cutting, drilling, gluing, or sanding.
Light Metalworking Tasks: Suitable for clamping thin metal sheets or small metal parts during grinding, polishing, or light assembly.
Furniture Repair & Assembly: Ideal for home or professional furniture repair, such as clamping loose chair legs while regluing.
DIY Home Improvement: Useful for various home projects, such as installing shelves or building wooden storage boxes.
Craft & Hobby Projects: Perfect for crafters working with materials like plywood, MDF, or foam board.

Frequently Asked Questions (FAQs)

Q1: What's the difference between black oxide and zinc-plated finishes, and how do I choose?

The main difference lies in corrosion resistance and use environment:

Black oxide: Best for dry indoor workshops. It has good wear resistance but limited protection against moisture.
Zinc-plated: Ideal for humid environments or occasional outdoor use. It forms a barrier against water, preventing rust.

Q2: Can I use this clamp for materials other than wood, like plastic or glass?

Yes, but with caution. To protect delicate surfaces, wrap the jaw faces with soft materials (e.g., rubber pads, foam sheets, or cloth) before clamping.

Q3: How do I maintain the clamp to extend its service life?
