An M6 bolt measures approximately 0.2362 inches (or slightly more than 7/32″) in its outside thread diameter.
Understanding M6 Bolt Size in Inches
An M6 bolt is a metric fastener, where the "M" denotes "metric" and the "6" indicates that its nominal major (outside) thread diameter is 6 millimeters (mm). When converting this metric measurement to imperial units, specifically inches, an M6 bolt's diameter becomes approximately 0.2362 inches. For quick identification, this measurement is slightly larger than 7/32 of an inch.
Key Dimensions of an M6 Bolt
To provide a clear understanding, here are the standard dimensions for an M6 bolt, presented in both metric and imperial units:
| Feature | Metric Measurement | Imperial Equivalent |
|---|---|---|
| Nominal Diameter (D) | 6 mm | Approx. 0.2362 inches |
| Standard Thread Pitch | 1 mm | Approx. 0.0394 inches (1 thread per mm) |
- Nominal Diameter: This is the primary characteristic of an M6 bolt, referring to the outside diameter of its threads.
- Thread Pitch: The standard M6 bolt typically has a 1 mm pitch, meaning there is 1 millimeter between each thread. This is crucial for matching nuts and tapped holes correctly.
Identifying M6 Bolts
When working with various fasteners, accurately identifying an M6 bolt can be important. Here are a few practical tips:
- Measurement: Use a caliper to measure the outside diameter of the threads. An M6 bolt will consistently measure around 6 mm or 0.2362 inches.
- Visual Comparison: While not precise, familiarizing yourself with common bolt sizes helps. An M6 bolt is relatively small, often used in electronics, automotive components, and light machinery.
- Thread Gauge: For accurate pitch identification, a thread gauge can confirm the 1 mm pitch of a standard M6 bolt.
Understanding these dimensions is crucial for ensuring proper fit and secure fastening in various applications, whether you're working with metric or imperial systems.
