Spaare

Spaare refers to a specific type of bolt or screw characterized by its relatively smooth shank and a threaded portion at the tip. Unlike fully threaded bolts, spaare bolts have a significant unthreaded section. This design is often employed in applications where a precise grip or controlled tension is required. The unthreaded portion allows the bolt to pass through a clearance hole in one of the components being joined, with the threads engaging only in the other component. This can help to prevent stress concentrations that might occur if the threads were to engage in both parts. Spaare bolts are commonly found in machinery, automotive assemblies, and structural applications. They are typically made from various metals, including steel, stainless steel, and brass, depending on the environmental conditions and load requirements of the application. The head of a spaare bolt can vary, commonly featuring hexagonal, square, or carriage bolt styles, dictating the tool used for installation and removal. The specific diameter and length of the spaare bolt are determined by the thickness of the materials being joined and the required clamping force.
