Boltedforbindelser

Boltedforbindelser, also known as bolt connections, are mechanical joints that use one or more bolts to join two or more components together. They are widely used in civil engineering, automotive, aerospace, and structural construction where high strength, adjustability, and ease of maintenance are required.

The basic construction of a boltedforbindelse consists of a bolt, a nut, and at least one fastening element such as a washer or a key. The bolt is inserted through aligned holes in the workpieces and tightened by rotating the nut. Tightening creates axial clamping force that holds the components together, while the friction between the parts and the bolt shears any tendency for separation under load. Bolt connections can be simple or reinforced with additional components such as expansion bolts, lag screws, or anchor plates, which enhance stability in softer materials or uneven surfaces.

Common types of boltedforbindelser include static bolts used in permanent structures, quick‑release bolts for removable systems, and anchor bolts that secure foundations to concrete. The selection of material—steel, stainless steel, titanium, or alloy composites—depends on the load, environmental conditions, and corrosion resistance requirements. Design of the connection often follows national and international codes such as ASME, EN, or ASTM, ensuring safety factors and fatigue resistance are met.

Boltedforbindelser offer several advantages: they allow for disassembly and reassembly during maintenance, provide precise alignment, and can accommodate shafts and rods that support rotary motion. However, they require careful design to avoid shear failure, bolt loosening, or corrosion. Proper installation, torque control, and lubrication are critical for achieving the intended performance and longevity of the joint.
