Screws metric / inch

Screws metric / inch are dimensioned in either the metric system (millimeters) or the inch system (inches) for their length and size. Metric screws are common in countries using the metric system, while inch screws are prevalent in those using the imperial system. They are used in construction, manufacturing, and automotive industries where precise fastening is required. These screws must meet specific standards based on the application. For metric screws, ISO 898-1 defines mechanical properties of fasteners made of carbon and alloy steel, and DIN 933 covers hexagon head screws with full threads. For inch screws, ANSI B18.2.1 addresses hex bolts and screws, while ASTM A574 applies to alloy steel socket-head screws. Well-known manufacturers like Wilo, SMC, and Thomson Linear, along with other leading manufacturers, offer their 3D CAD models on 3Dfindit, including screws metric/inch.
