When working with threaded inserts, understanding decimal and fractional measurements is crucial. This article clarifies the difference between 0.7 and 5/8, particularly relevant when choosing the right E-Z LOK™ Thin Wall threaded insert. While these numbers might seem close, they represent different drill bit sizes, impacting insert selection and application.
Decimal vs. Fraction: Understanding the Difference
The key to comparing 0.7 and 5/8 lies in converting them to a common format. The decimal 0.7 represents seven-tenths. To compare it to the fraction 5/8, convert 5/8 to a decimal by dividing 5 by 8. This results in 0.625. Therefore, 0.7 is larger than 5/8 (0.625).
E-Z LOK™ Thin Wall Inserts: Why Size Matters
This seemingly small difference is significant when selecting drill bits for installing threaded inserts. E-Z LOK™ Thin Wall inserts are designed for applications where size and weight are critical. They utilize a modified external thread, reducing the required hole diameter compared to standard wall inserts. However, this design necessitates using a larger drill bit than typically used with the corresponding tap.
Drill Bit Selection: A Practical Example
Consider an example highlighting the importance of accurate measurements. A standard wall insert with a 5/8-11 external thread might require a 17/32 drill bit. Conversely, a thin wall insert, even with the same 5/8-11 external thread but a different internal thread, might necessitate a 37/64 drill bit. This difference underscores how seemingly minor variations in decimal and fractional values translate to distinct drill bit sizes. Choosing the incorrect drill bit can compromise the integrity of the insert and the application. Always consult the manufacturer’s specifications to ensure proper drill bit selection.
Ensuring Accurate Measurement for Successful Installation
Precise measurements are paramount for successful installation. When working with E-Z LOK™ Thin Wall inserts, meticulously refer to the product specifications. These specifications provide the necessary drill bit size corresponding to each insert’s unique external and internal thread dimensions.
In conclusion, understanding the difference between decimal and fractional values like 0.7 and 5/8 is fundamental when working with threaded inserts. While 0.7 is larger than 0.625 (the decimal equivalent of 5/8), the practical implication lies in selecting the correct drill bit size for optimal installation of E-Z LOK™ Thin Wall inserts. Always prioritize accuracy and consult manufacturer guidelines for specific drill bit recommendations.
