Bolts are threaded rods or pins that fasten objects together. They usually have a head at one end and a thread at the other. Bolts are secured by threaded nuts, and are available in both metric and non-metric designations. Metric nuts vary by inner diameter (ID) and are usually labeled with the letter “M” followed by the ID in millimeters (mm). For example, M.16 bolts have an inner diameter of 1.6 mm, while M2 bolts have an ID of 2.0mm. Non-metric bolts also vary by inner diameter, but are measured in inches (in) and eighths of inches. Although some English bolts are labeled by ID, others carry a specially-numbered designation. Examples include #0000, #000, #00, #0, #1, and #2 bolts. |
