Large Screw

A large screw is a cylinder with thread applied. On one side of the cylinder there is a large flat cylindrical head fitted with a slot.

The recess shape on the head can be designed for a flat screwdriver, a cross recess, a Torx slot, or a hex socket. This is needed for convenient installation on the joined parts, depending on the installation force required for the fastener.

Applications

The application range of large screws is extensive: mechanical engineering, machine tool manufacturing, shipbuilding, and other industries. This item of hardware is one of the most widely used fastener types. Screws simplify the installation of heavy structures in both horizontal and vertical positions.

Features

The material for manufacturing large screws is typically carbon steel, alloy steel, stainless steel grade A2, brass alloy, and others. Additionally, the product can be coated with a protective layer, which makes its use possible under unfavorable conditions. This is especially relevant when used in places with high humidity and temperature fluctuations for products made of carbon steel.
