Bolts are indispensable in daily life and industrial manufacturing. Bolts are also known as industrial meters. It can be seen that the bolts are widely used. The application scope of bolts and nuts includes: automotive,construction,electronic products, mechanical products, digital products, electrical equipment, electromechanical mechanical products. Bolts and nuts are also useful in ships, vehicles, water conservancy projects, and even chemical experiments. Anyway, bolts are used in many places. Precision bolts used on special digital products. Miniature bolts for DVDs, cameras, glasses, watches, electronics, etc .; general bolts for TVs, electrical products, musical instruments, furniture, etc .; for engineering, construction, and bridges, large bolts and nuts are used transportation appliances, aircraft, trams, automobiles The equivalent is the combination of large and small bolts.
Nuts are parts that are tightly connected with mechanical equipment. Only through internal threads can nuts and bolts of the same specifications be connected together. For example, M4-P.7 nuts can only be connected with M4-P.7 series bolts (in nuts, the inner diameter of M4 nuts is about 4mm, and the distance between 0.7 fingers and two threaded teeth is 0.7mm). Similarly, for example, 1/4-20 nuts can only be matched with 1/4-20 nuts (1/4 finger nuts have an inner diameter of about 0.25 inches, 20 fingers have 20 teeth per inch).
