coarse pitch

**coarse pitch**

The term “coarse pitch” refers to a larger or wider thread spacing in screws, bolts, and other threaded fasteners. It means the distance between adjacent threads is greater than in fine pitch threads, resulting in fewer threads per inch or millimeter. Coarse pitch threads are typically used in applications where quick assembly or disassembly is needed, or where the fastener must withstand rough conditions such as dirt, corrosion, or mechanical stress. They provide greater resistance to stripping and are easier to manufacture, making them a common choice in construction, automotive, and heavy machinery industries.
