DIN 7965 Screwed Insert

DIN 7965 screwed inserts are threaded fasteners manufactured according to the German DIN 7965 standard, ensuring strict dimensional accuracy and uniform technical specifications. They are designed for use with pre-tapped holes in soft materials such as aluminum or magnesium alloys, forming high-strength internal threads. These inserts solve common issues like thread stripping or loosening and offer standardized, reliable threaded connections suitable for industrial assembly applications, ensuring interchangeability across different manufacturers and equipment.

Product Features

Standardized Design: Manufactured strictly according to DIN 7965, with precise dimensional tolerances, compatible with standard threaded holes worldwide, ensuring cross-vendor part interchangeability.
High Connection Strength: Load is transmitted through the engagement of internal and external threads, significantly enhancing the thread’s load-bearing and impact resistance in soft base materials, preventing thread stripping or loosening.
Stable and Reliable Installation: Requires pre-tapped holes for installation; once installed, the insert tightly engages with the base material, maintaining connection stability even under vibration.
Wide Material Options: Available in carbon steel, stainless steel, and other materials; coating options can be selected to suit different applications, expanding the usage scenarios.
Strong Repairability: Damaged threaded holes can be quickly restored by replacing the insert without changing the base material, reducing maintenance costs.

Applications

Industrial Equipment: Thread reinforcement in housings and components of machine tools and automated equipment.
Automotive Manufacturing: Pre-installing threads in engine-related components and chassis structures to withstand vibrations and shocks during vehicle operation.
Aerospace: Thread reinforcement in aluminum-based lightweight components to meet high-precision and high-reliability assembly requirements.
Precision Instruments: Threaded connections in critical components of medical devices and measurement instruments to ensure precise operation.
