FAQS on hex nut sizes metric

What are the common metric hex nut sizes?

Q: What are the standard metric hex nut sizes?

A: Common metric hex nut sizes range from M3 to M24, with thread pitches specified by ISO standards. Sizes like M6, M8, and M10 are widely used in industrial applications. Always check DIN 934 or ISO 4032 standards for exact dimensions.

How do anchor bolt sizes correlate with metric hex nuts?

Q: How to match anchor bolt sizes with metric hex nuts?

A: Anchor bolt thread diameters (e.g., M12, M16) must align with the hex nut’s internal thread size. For example, an M12 bolt requires an M12 hex nut. Ensure bolt length accounts for washer and nut thickness.

What are standard metric washer sizes for hex nuts?

Q: What washer sizes pair with metric hex nuts?

A: Standard metric washers (e.g., DIN 125) match hex nut sizes, such as 12mm washers for M12 nuts. Inner diameter should slightly exceed the bolt’s thread diameter. Always verify compatibility using ISO 7089 standards.

Are metric anchor bolts interchangeable with imperial sizes?

Q: Can metric anchor bolts replace imperial ones?

A: Metric and imperial anchor bolts are not interchangeable due to differing thread pitches and diameters. For example, an M10 bolt (10mm) doesn’t fit a 3/8" (9.525mm) nut. Always use matching measurement systems.

How to measure metric hex nut dimensions accurately?

Q: What’s the correct way to measure a metric hex nut?

A: Measure the nut’s width across flats (e.g., 17mm for M10) and thread diameter (e.g., 10mm for M10). Use a caliper for precision and refer to ISO standards for tolerance ranges. Thread pitch gauges help verify compatibility.
