[Technical Data] Relationship between Screw Grade and Fit Length

Selecting the appropriate grade and effectively utilizing tolerances leads to stable processing.

I will introduce the relationship between "screw grade and fit length." The grade of a screw is determined by the relationship between the "fit classification" and the "fit length." Since the screw grade indicates the position of the tolerance, selecting the appropriate grade and effectively utilizing the tolerance leads to stable processing. 【Examples of Fit Classification Application】 ■ Precision - Especially for precision screws with minimal play ■ Medium - General-purpose screws used in machinery, instruments, structures, etc. ■ Coarse - Screws used in environments prone to dirt and scratches, such as in construction work and installation, or screws that are difficult to process, like those threaded onto hot-rolled bars or those threaded into long blind holes. *For more details, please refer to the PDF document or feel free to contact us.

[Technical Information] Causes and Countermeasures for the Enlargement of "Male Threads"

Detailed causes and countermeasures for issues such as excessive cutting around the mouth!

Normal female threads will stop within two rotations of the stop screw gauge. However, issues such as misalignment of the spindle, spindle runout, and the use of worn taps can lead to problems like "enlargement due to excessive cutting at the mouth," "enlargement due to insufficient cutting edge resulting in thread skipping," and "enlargement due to poor feed balance (excessive or insufficient cutting)." This technical document provides detailed information on the causes of "female thread" enlargement and examples of countermeasures.

Technical Information: About Super Hard Taps

Introducing our "carbide taps," which can process stable and high-precision screw threads.

In recent years, the machines used for tapping have become specialized, automated, and have adopted NC machines and machining, leading to labor-saving advancements. In response to this era, we recommend our carbide taps, which are well-received for mass production and cost reduction. When used properly, they have been proven to have over 50 times the durability compared to standard HSS taps. The material of the carbide taps is carefully selected, using ULTRA-FINE-GRAIN-CARBIDE made from ultra-fine tungsten carbide and high cobalt, which are deemed suitable for taps. [Contents] ■ Features of Yamawa carbide taps ■ Points to note during use ■ Examples of main work materials, cutting speeds, and cutting oils ■ Hardness and toughness of carbide and HSS materials ■ Comparison of thread count and wear amount of engagement parts between carbide taps and HSS taps ■ Examples of carbide tap usage and lifespan comparison *For more details, please refer to the PDF materials or feel free to contact us.

Knowledge bag for when you're in trouble: Nominal sizes and diameters of pipe threads

Common questions and concerns about screws resolved! Screw standards edition.

YAMAWA will respond to the inquiries received from customers. This document also includes some minor speculations. 【Contents】 ■Inquiry I know how to express unified screws like "1/4-20UNC" and "1/2-13UNC" in inches. For the "1/4-20UNC" external thread, I understand that the outer diameter reference dimension is 1/4 of 1 inch (25.4mm), which is "6.35mm." However, the outer diameter reference dimension for the pipe thread "G1/4-19" (old standard: PF1/4-19) is 13.157mm, which does not match at all. How should I understand this? *For more details, please refer to the PDF document at the link below.
