EMUGE Self-Locking Internal Threads

Product catalog summary
Introduction
The document introduces the EMUGE SELF-LOCK integrated thread locking system, which serves as an alternative to traditional thread locking methods that often require additional components and can be costly or sensitive to temperature changes. The SELF-LOCK system is designed to prevent involuntary loosening of threads, particularly under dynamic stress conditions.
Standard vs. SELF-LOCK Threads
Standard screw connections often concentrate stress on the first thread, leading to potential stripping, especially in soft materials. The SELF-LOCK system distributes stress evenly across the thread length, reducing the risk of stripping and allowing for repeated use.
Features of EMUGE SELF-LOCK
  • Integrated thread locking within the internal thread.
  • Modified profile with a 30-degree ramp surface for self-locking.
  • Easy assembly with no risk of forgetting locking devices.
  • Compatible with standard external threads.
  • Even stress distribution prevents thread stripping.
  • Cost-effective with no additional components needed.
  • Maintains holding power under dynamic stress.
  • Allows repeated loosening and re-tightening without loss of function.
  • Can be produced with EMUGE taps, cold-forming taps, or thread milling cutters.
Performance Comparison
The EMUGE SELF-LOCK thread maintains holding power under dynamic stress better than standard threads, even after repeated use. The design ensures a more even load distribution, relieving stress on the first thread and distributing it more evenly across the thread length.
Designation and Application
The SELF-LOCK profile is marked with "LK" before the thread size, with "BT" or "TT" indicating the direction of the ramp surface. The system is suitable for both blind and through-hole threads, with specific applications for each.
Product Finder and Cutting Data
Guidelines are provided for selecting suitable threading tools and cutting speeds based on material type and application conditions. Recommendations for coolant-lubricants and the suitability of various threading tools for different materials are included.
Overview
This document provides technical specifications and guidelines for various cutting tools and thread systems, focusing on the EMUGE SELF-LOCK thread system. It includes details on tool materials, coatings, applications, and recommended practices for optimal performance.
Specifications
Specifications for cutting materials such as HSSE and coatings like TIN and GLT-1 are outlined. Dimensions and tool identifiers for different thread sizes and types, including SELF-LOCK machine taps and cold-forming taps, are provided. The thread depth and hole type are specified, with maximum depths for different applications.
Applications and Materials
The tools are applicable to a range of materials, categorized under codes such as P, M, K, N, and S, which correspond to different material types and conditions. The document specifies the suitability of tools for these materials, ensuring compatibility and performance.
Technical Information
Detailed technical information is provided, including recommended preparatory diameters for thread holes, crucial for maintaining thread tolerance. The document emphasizes the importance of stable tool and workpiece clamping and the use of high-quality carbide twist drills.
Recommendations
For difficult-to-form materials, such as aluminum cast alloys, a smaller preparatory diameter is recommended. The document advises on optimizing tool life by adjusting preparatory diameters while ensuring compliance with thread tolerance.
Gauging and Standards
The document discusses the gauging of EMUGE SELF-LOCK threads, recommending a two-piece gauge system for accurate measurement. It notes the absence of a universal standard for these threads, highlighting the importance of using EMUGE-specific gauges.
Ordering Information
Examples of ordering codes are provided for various tools, facilitating easy identification and procurement.

SELF-LOCK – Die integrierte Gewindesicherung · SELF-LOCK – The Integrated Thread Locking System Schraubenverbindungen sind lösbare Verbindungen. Um ungewolltes Lösen besonders unter dynamischen Beanspruchungen zu vermeiden, bedarf es häufig zusätzlicher Sicherungselemente. Diese verursachen Kosten, sind nur bedingt wiederholt verwendbar und zum Teil temperaturempfindlich. Screw connections are generally made so that they can be loosened again. If an involuntary loosening of threads, especially under dynamic stress, must be avoided it is often necessary to use additional locking devices. In many...
