Discussion Overview
The discussion focuses on the specifications and dimensions related to tapped holes, specifically for M6 size bolts. Participants explore the relationship between the diameter of the tapped hole and the corresponding bolt size, including considerations for drilling and threading.
Discussion Character
- Technical explanation, Debate/contested
Main Points Raised
- One participant seeks clarification on whether a tapped M6 hole is 6mm in diameter for a 6mm diameter bolt.
- Another participant confirms the initial understanding with a simple affirmation.
- A different participant questions if the inquiry pertains to the size of the hole to be drilled for tapping an M6 bolt, noting that it is not simply 6mm and depends on the number of threads on the bolt.
- One participant emphasizes that while the tap drill size is smaller than the nominal diameter, the major diameter of an M6 thread is indeed 6mm, cautioning that measurements may yield the minor diameter instead.
- Another participant introduces the idea that if the unthreaded part of the bolt needs to fit in the hole, two drill sizes may be necessary: one for the threaded portion and another for the unthreaded upper part.
Areas of Agreement / Disagreement
There is no clear consensus; participants present differing views on the appropriate hole size for tapping and the implications of bolt dimensions.
Contextual Notes
Participants reference the need for tap drill size charts and the importance of distinguishing between major and minor diameters, indicating potential limitations in understanding without these resources.
