Thread Master 4X48 – UNF – 3B Thread Plug Gage

Descripción

The Thread Master 4X48 – UNF – 3B Thread Plug Gage is a precision tool designed for verifying the accuracy and conformity of threaded components with 4-48 Unified National Fine (UNF) threads and a 3B thread class. Here are its key specifications and features:

• Thread Size and Type: The Thread Master 4X48 plug gage is specifically designed for 4-48 Unified National Fine (UNF) threads, which are commonly used in precision applications where finer thread pitches are required.
• Thread Class: It conforms to the 3B thread class, which specifies the tolerance and fit of internal threads, ensuring compatibility and proper engagement with mating external threads.
• Plug Gage Design: This tool is a plug gage, meaning it checks internal threads by screwing into them. The 3B designation ensures that the gage has a tight tolerance for precise measurement of the internal thread’s pitch diameter and thread form.
• Accuracy and Tolerance: The Thread Master 4X48 – UNF – 3B Thread Plug Gage is manufactured to high accuracy standards, typically with tolerances within a few thousandths of an inch or micrometers, ensuring precise measurement results and compliance with industry specifications.
• Material and Finish: These plug gauges are commonly made from durable materials such as tool steel or stainless steel, with a smooth surface finish for accurate and consistent measurements, as well as resistance to wear and corrosion.
• Usage: The 4X48 – UNF – 3B Thread Plug Gage is widely used in manufacturing, quality control, and inspection processes to verify the thread dimensions of machined parts with 4-48 UNF internal threads, ensuring they meet design requirements and functional standards.
• Identification: Each plug gage is typically marked or labeled with clear identification, including thread size, thread type, thread class, and gauge designation, making it easy for users to select the appropriate gage for specific measurement tasks.
• Calibration Certificate: Many Thread Master plug gauges come with a calibration certificate traceable to national or international standards, providing assurance of accuracy and compliance with industry regulations.

In summary, the Thread Master 4X48 – UNF – 3B Thread Plug Gage is an essential tool for ensuring the accuracy, compatibility, and quality of 4-48 UNF internal threads in various manufacturing and engineering applications, contributing to efficient and reliable threaded connections.
