FAQ

Question?
What is the thread pitch for this M12 nut?

Answer

Unless otherwise specified, M12 nuts use the standard coarse thread pitch, which is 1.75mm.

Question?
What is the recommended wrench or socket size for this nut?

Answer

The standard width across flats (AF) for an M12 hex nut is typically 18mm, though 19mm can also be found. It is best to measure the part to ensure you use the correct tool.

Question?
Is this brass material suitable for outdoor or marine environments?

Answer

Brass offers good corrosion resistance for many outdoor applications. However, for harsh marine environments with constant saltwater exposure, marine-grade stainless steel (e.g., 316) or silicon bronze may offer superior long-term durability.
