From the Simplest to the Most Sophisticated, Types of Screws Available in the Market

From its first appearance in Europe in the 14th century to its widespread use in the 19th century and up to the present day, the screw has undergone significant evolution. This progression has contributed to transforming it into a more reliable, high-performing component suitable for various applications. Today, there are different types of screws, each designed based on the involved structure and the specific functions it must perform. Let’s delve into them in detail.

The standard screw, with a linear structure and standard threading, represents the foundation for many applications. Made in steel or metal alloys, it offers uniform and long-lasting strength. It is screwed into the material to be fastened using a complementary thread, which can be prepared in advance with a drill and tap or generated on-the-spot by the screw itself, depending on the material being worked on. Its ease of installation makes it a versatile choice across various sectors, from construction to manufacturing industries.

The self-tapping screw is designed to carve its path through material, eliminating the need for preliminary drilling. It usually features a pointed end to faciltate the entrace into the hole, and sometimes the entire body is conical rather than cylindrical. Made in high-strength steel, this screw type is ideal for metal-to-metal or metal-to-plastic connections. Its advanced threading ensures a firm and secure grip, reducing installation time and enhancing joint efficiency. Common applications include furniture assembly, fastening accessories, and constructing metal frames.

The self-drilling screw comes with an exceptionally sharp and cutting tip, allowing it to penetrate thin materials without preliminary drilling. Crafted from hardened steel, it is particularly suitable for applications requiring speed and precision in drilling. Its ability to drill and fasten simultaneously makes it the preferred choice in projects demanding swift assembly, such as metal sheets, cladding, light metal structures, and thin plastic materials.

The trilobular self-forming screw stands out for its ability to self-drill and self-tap and is currently the most advanced screw type. Its distinct trilobular stem instead of a cylindrical one enables the creation of a thread during screwing, effectively transforming the screw into a tap to be threaded. Its self-drilling capability streamlines installation, while self-tapping ensures a firm and reliable grip over time. This screw is particularly suitable for applications requiring robust connections and high load resistance, proving essential in mechanically tense structures. It finds extensive use in assembling complex metal structures, structural components, and heavy machinery.
