\u00a0If you\u2019re new to hardware, one of the first confusions you\u2019ll face is telling screws, bolts, and nuts apart.
Here\u2019s a quick, clear breakdown so you\u2019ll never mix them up again<\/strong>.<\/p>

\ud83d\udd29 Screw \u2014 the one that holds on its own\"\u9ed1\u92fc\u5341\u5b57\u6728\u87ba\u7d72\u8207\u81ea\u653b\u87ba\u7d72\u7d44\u5408\uff0c\u87ba\u7d72\u53ef\u76f4\u63a5\u54ac\u5165\u6750\u6599\uff0c\u4e0d\u9700\u87ba\u5e3d\u5373\u53ef\u56fa\u5b9a\u3002\"<\/strong><\/h4>

Personality:<\/strong>
\u201cI work solo. I don\u2019t need a partner.\u201d<\/p>

Key traits:<\/strong><\/p>

      • Doesn\u2019t require a nut<\/p><\/li>

      • Cuts or threads directly into the material<\/p><\/li>

      • Common in electronics, furniture, and small hardware<\/p><\/li>

      • Includes wood screws, self-tapping screws, and self-drilling screws<\/p><\/li><\/ul><\/li><\/ul><\/li><\/ul>

        \ud83d\udd27 Bolt \u2014 the one that must<\/em> work with a nut\"\u4e0d\u93fd\u92fc\u516d\u89d2\u87ba\u6813\u793a\u610f\u5716\uff0c\u87ba\u6813\u9700\u642d\u914d\u87ba\u5e3d\u4f7f\u7528\uff0c\u662f\u91cd\u578b\u6a5f\u68b0\u8207\u7d50\u69cb\u4ef6\u5e38\u7528\u7684\u9ad8\u5f37\u5ea6\u6263\u4ef6\u3002\"<\/strong><\/h4>

        \u201cNo nut, no job.\u201d<\/p>

        Key traits:<\/strong><\/p>

            • Always requires a nut<\/p><\/li>

            • Holds parts together using clamping force<\/p><\/li>

            • Used in machinery, vehicles, steel structures, and equipment<\/p><\/li>

            • Strength grades (8.8 \/ 10.9 \/ 12.9) belong to the bolt category<\/p><\/li><\/ul><\/li><\/ul><\/li><\/ul>

              \ud83d\udd29 Nut \u2014 the bolt\u2019s perfect partner\"\u4e0d\u93fd\u92fc\u516d\u89d2\u87ba\u5e3d<\/strong><\/h4>

              Personality:<\/strong>
              \u201cI make the bolt stronger.\u201d<\/p>

              Key traits:<\/strong><\/p>

                  • Internal threads (female threads)<\/p><\/li>

                  • Works with a bolt to create clamping force<\/p><\/li>

                  • Comes in many types: hex nut, nylon lock nut, self-locking nut, etc.<\/p><\/li>

                  • Determines the joint\u2019s locking performance and safety<\/p><\/li><\/ul><\/li><\/ul><\/li><\/ul>

                    The Simple Rule (Engineers Use This Every Day)<\/strong><\/h4>

                        • Needs a nut \u2192 Bolt<\/strong><\/p><\/li>

                        • Bites directly into the material \u2192 Screw<\/strong><\/p><\/li>
