Types of metal pins play a fundamental role in mechanical engineering, manufacturing and construction. These small cylindrical or conical parts allow components to be fixed, aligned and secured with precision. Although they often go unnoticed, choosing the right one can make the difference between a safe assembly and one prone to failure, which is why turning to a specialized metal pin manufacturer <\/a><\/strong>is decisive for guaranteeing the precision and strength each application demands. <\/p>\n\n\n\n

Most commonly used types of metal pins<\/h2>\n\n\n\n

Pins are classified according to their shape, function and installation system. The main ones are described below: <\/p>\n\n\n\n

\n
\n

Cylindrical (or straight) pins<\/strong><\/h3>\n\n\n\n

These are rods of uniform section, manufactured to strict tolerances (down to \u00b10.01 mm), which allow a precise interference fit. They are used to align components in machinery, engines or precision equipment. They are usually made of hardened steel, giving them a shear strength of up to 1200 MPa. <\/p>\n<\/div>\n\n\n\n

\n

Conical (taper) pins<\/strong><\/h3>\n\n\n\n

Wedge-shaped, with a decreasing diameter. Their insertion creates self-locking, facilitating precise alignments and easy disassembly. They are used in tools, dies or automotive machinery. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Cotter (or split) pins<\/strong><\/h3>\n\n\n\n

U-shaped clips that pass through holes and are bent to secure parts. Widely used in brake systems, suspension and agricultural machinery. Easy to install and inexpensive, although single-use and with limited strength (60-70 MPa). <\/p>\n<\/div>\n\n\n\n

Other pins
<\/h3>\n\n\n\n

These include clevis pins (with a head and a hole for a cotter pin), threaded pins (pin + screw), and quick-release pins (bayonet type). They are used in pivoting or removable joints.
