Hex Nut ZP

Product Introduction

• Standard Name: Zinc Plated Hex Nut.

• Common Names: Galvanized Nut, Electrogalvanized Hex Nut.

• Product Definition: A hexagonal-shaped internal thread fastener with an electrogalvanized surface finish. This is the world's most universal and economical standard rust-proof nut, providing reliable corrosion protection for threaded connections. Suitable for most indoor and standard industrial environments.

Hex Nut ZP Key Features

• Zinc Plated (ZP): Provides basic rust protection and a bright silver metallic luster, enhances corrosion

  resistance, suitable for indoor or mildly humid environments, and complies with RoHS standards.

• Hexagonal Design: Standard hexagonal shape for easy tightening with wrenches or socket tools,

  ensuring efficient installation.

• Material and Strength: Commonly made of carbon steel, with strength grades such as Grade 5, 8, or

  10.9 to withstand corresponding loads; conforms to standards such as DIN 934 and ISO 4032.

• Various Sizes: Diameters M4-M36, supports coarse or fine threads, standard thickness.

• Advantages: Economical and practical, aesthetically pleasing, and readily available, but not suitable

  for highly corrosive environments.

Working Principle

• 1Threaded Fit: The internal thread matches the external thread of the bolt, generating axial clamping

  force through rotation.

• Preload Generation: When torque is applied, the nut compresses the connector; the zinc plating

  reduces friction, improves efficiency, and prevents seizing.

• Protection Mechanism: The zinc layer acts as a sacrificial anode, preferentially oxidizing in corrosive

  environments to protect the substrate.

• Anti-Loosening Control: Combined with washers or locking designs, it resists loosening due to

  vibration; the principle involves friction and mechanical interlocking.

Product Applications

• Machinery Manufacturing: Used with bolts to secure equipment parts, machine tools, or brackets.

• Construction Engineering: Economical and practical for fixing indoor steel structures or pipes.

• Automotive and Electronics: Assemble vehicle frames, electrical housings, or circuit boards.

• Home and DIY: Aesthetically pleasing and rust-free for furniture assembly or routine maintenance.

• Industrial Equipment: Used as standard components in production lines or warehouse structures.
