 An External Tooth Washer is a type of lock washer featuring serrated teeth on the outer edge. These teeth bite into the mating surface and the underside of the bolt head or nut, creating high friction that prevents loosening due to vibration, movement, or thermal expansion. External tooth washers are widely used where secure fastening and electrical grounding are required.

Manufactured from stainless steel, these washers provide excellent durability, strength, and corrosion resistance for long-term performance.

Key Features:

• External serrations for effective locking action

• Prevents loosening caused by vibration and shock

• Enhances electrical conductivity and grounding

• Corrosion-resistant stainless steel construction

• Suitable for light to medium load applications

Grades (Material): SS 304 / SS 316 SS 304 (Stainless Steel 304)

• Composition: 18% Chromium, 8% Nickel

• Corrosion Resistance: Good for general-purpose and moderately humid environments

• Strength: Good mechanical strength and flexibility

• Usage: Electrical panels, machinery, automotive assemblies, indoor and light outdoor applications

• Cost: Economical compared to SS 316

SS 316 (Stainless Steel 316)

• Composition: 16% Chromium, 10% Nickel, 2% Molybdenum

• Corrosion Resistance: Excellent, especially against saltwater, chemicals, and acidic environments

• Strength: High durability and resistance to pitting and rust

• Usage: Marine equipment, coastal installations, chemical plants, outdoor and high-humidity environments

• Cost: Higher due to superior corrosion resistance

Applications & Usage Applications:

1. Electrical & Electronic Equipment: Provides secure fastening and grounding in panels and enclosures.

2. Machinery & Equipment: Prevents loosening of fasteners in vibrating or moving parts.

3. Automotive & Engineering: Used in assemblies requiring reliable locking performance.

4. Construction & Fabrication: Ensures joint stability in metal structures.

5. Marine & Outdoor Installations: SS 316 is preferred for corrosive environments.

Usage Guidelines:

• Install the washer with the teeth facing the contact surface for maximum grip.

• Use with matching stainless steel bolts and nuts to avoid galvanic corrosion.

• Select SS 304 for general indoor or light outdoor use.

• Select SS 316 for harsh, marine, or chemical environments.

A Spring Washer (also known as a split lock washer) is a mechanical fastener designed to prevent loosening of bolts and nuts due to vibration, shock, or dynamic loads. It is split and slightly twisted to create a spring effect, which maintains tension in the fastened joint and increases friction between the nut and the surface.

Spring washers made from stainless steel offer excellent strength, durability, and corrosion resistance, making them suitable for both indoor and outdoor applications.

Key Features:

• Maintains preload in bolted joints

• Prevents loosening caused by vibration

• Provides elastic tension under load

• Corrosion-resistant stainless steel construction

• Long service life and reliable performance

Grades (Material): SS 304 / SS 316 SS 304 (Stainless Steel 304)

• Composition: 18% Chromium, 8% Nickel

• Corrosion Resistance: Good for general-purpose and moderately humid environments

• Strength: Good mechanical strength and elasticity

• Usage: Indoor equipment, machinery, electrical panels, furniture

• Cost: Economical compared to SS 316

SS 316 (Stainless Steel 316)

• Composition: 16% Chromium, 10% Nickel, 2% Molybdenum

• Corrosion Resistance: Excellent, especially against saltwater, chemicals, and acidic environments

• Strength: High durability and resistance to pitting and rust

• Usage: Marine equipment, coastal installations, chemical plants, outdoor machinery

• Cost: Higher due to enhanced corrosion resistance

Applications & Usage Applications:

1. Machinery & Equipment: Prevents loosening of bolts in moving or vibrating machines.

2. Automotive & Engineering: Used in engines, assemblies, and mechanical structures.

3. Electrical Panels & Enclosures: Maintains secure connections under thermal expansion.

4. Construction & Fabrication: Ensures joint stability in metal structures.

5. Marine & Outdoor Installations: SS 316 spring washers are ideal for corrosive environments.

Usage Guidelines:

• Always use with matching stainless steel bolts and nuts to avoid galvanic corrosion.

• Select SS 304 for general indoor or light outdoor use.

• Select SS 316 for harsh, marine, or chemical environments.

• Ensure proper tightening torque for optimal spring action.
