Ideal for lightweight, compact assemblies where precise, secure fastening is needed without the bulk of traditional nuts and bolts.

Home Appliances:

External Teeth Lock Nuts are used in securing components like control panels, wiring enclosures, and metal casings.

Construction and HVAC:

Used to hold together ductwork, brackets, and metal framing, where quick installation is beneficial.

Furniture Assembly:

Provides secure, tool-free fastening for panel assembly in furniture, shelving, and cabinetry.

Salt Spray Test:

Measures corrosion resistance, particularly for zinc-plated or coated External Teeth Lock Nuts.

Tensile Strength Testing:

Assesses the nut’s ability to withstand load forces.

Dimensional Inspection:

Ensures that the nuts conform to specified dimensional tolerances, which is critical for compatibility with corresponding screws or panels.

Hardness Testing:

Verifies that the material meets the required hardness levels for specific applications.

Vibration Testing:

Important for automotive and industrial applications, this test ensures that External Teeth Lock Nuts do not loosen or lose integrity under high-vibration conditions.

Torque Testing:

Evaluates the torque required for installation and removal, ensuring that the External Teeth Lock Nut remains secure while still allowing easy installation.

Material Selection:

We start by choosing high-quality raw materials that meet the specific requirements of each application, such as corrosion resistance or strength.

Forming Process:

Using precision stamping, we shape each External Teeth Lock Nut from sheet metal or other base materials. The forming process includes creating slots, threads, and specific shapes to suit various applications.

Heat Treatment(if necessary):

For certain materials, heat treatment is applied to increase strength, hardness, and wear resistance.

Surface Treatment:

Depending on the application, we add protective coatings to enhance durability, corrosion resistance, or appearance.

Quality Control:

Each batch undergoes rigorous testing and inspection to ensure they meet the required specifications before being packed and shipped.
