The external hexagonal screw with a washer step and a machine-threaded, anti-loosening, and anti-slip point-screw design is a fastener that integrates multiple functions. Its core features can be categorized into three key areas: structural characteristics, anti-loosening technology, and application advantages.
1. Structural Design
The external hexagonal head provides a high-torque bearing surface, suitable for operation with a wrench or socket, facilitating high-strength tightening and being more resistant to thread stripping than an internal hexagonal head.
Internal flange design: The flange increases the contact area, distributing pressure, protecting the surface of the fastened component, and preventing indentations.
Integrated washer step
Pre-installed washers: Reduce the need for additional washers, prevent loosening, and improve sealing, providing dust and water resistance.
Step structure: Precisely control screw insertion depth to avoid overtightening, making it suitable for assembly requiring a fixed gap.
Machine-thread: Mate with a nut or pre-threaded hole, it provides high tensile strength and is suitable for joining metal parts.
II. Core Anti-Loosening Technology
Anti-Loosening Design
Glueing Process: The threaded portion is pre-coated with nylon glue. Frictional heat generated during threading activates the adhesive, which cures to form an elastic lock, resisting loosening caused by vibration.
Secondary Anti-Loosening: The adhesive layer can be reused 2-3 times, making it suitable for equipment requiring maintenance.
Mechanical + Chemical Dual Security: Combining friction locking on the flange surface with chemical adhesive fixation, it is suitable for high-frequency vibration environments.
III. Application Advantages
High Compatibility: Covers common sizes from M3 to M6, adapting to most machine-threaded holes without requiring hole design modifications. Available in stainless steel or carbon steel for corrosion resistance or high-strength requirements.
Assembly Efficiency: The integrated design reduces the number of parts, minimizing the risk of loss and making it suitable for fast installation on automated production lines.
Typical Applications: Automotive Electronics: Securing onboard controllers and sensors (vibration resistance).
Industrial Equipment: Motor end caps and transmission components (high anti-loosening requirements).
Consumer Electronics: Server chassis and heat dissipation modules (balancing strength and aesthetics).
Outstanding Value Compared to Ordinary Screws
Loosening Prevention: Ordinary screws rely on spring washers, which are prone to loss. This product utilizes nylon glue and flanges for dual security.
Vibration Resistance: Ordinary screws have poor vibration resistance, while this product offers excellent vibration resistance (suitable for environments above 2000Hz).
Assembly Complexity: Ordinary screws require separate washers, while this product utilizes an integrated design, reducing the number of steps.
Through its integrated structure and upgraded anti-loosening technology, this screw solves the loosening problem of traditional screws in vibrating environments, while improving assembly efficiency and reliability. It is an ideal fastening solution for precision industries.
