pultteihin

Pultti is a common mechanical fastener consisting of a cylindrical shaft with external threading and a head. It is designed to be used together with a nut or a tapped hole to join two or more components. The illative plural form pultteihin is a Finnish grammatical form that means “to bolts” or “into bolts,” and it is used to express direction or destination in sentences. In practice, pultteihin appears mainly in technical or instructional contexts when describing actions involving bolts or assemblies.

In hardware and construction, bolts are selected by size, thread pitch, material, and strength. Typical types include hex bolts (kuusikulmainen pultti), carriage bolts (kantapultti), and anchor bolts (ankk.pultti). Materials range from carbon steel to stainless steel and alloy variants, with coatings such as zinc or phosphate to improve corrosion resistance. The choice of bolt is guided by load requirements, environmental conditions, and the presence of mating nuts or threaded holes.

Standards and installation practices are important for reliability. Bolts are manufactured to international standards that specify diameter, thread type (usually metric, e.g., M6, M8), and strength class (for example 8.8 or 10.9). Proper torque, the use of washers when needed, and appropriate lubrication or anti-seize measures help achieve the intended clamping force and prevent damage. When assembling, components may be positioned and secured with bolts that are then directed toward or fixed into the appropriate bolts or bolt holes, a situation where the illative form pultteihin is contextually relevant.
