Adjustment Bolt: Load Capacity 500-5000 kg per bolt

Component Specifications

Definition

An adjustment bolt is a precision-engineered threaded fastener designed to provide controlled vertical movement for leveling and stabilizing industrial machinery. It typically features a hex head or other drive configuration for torque application, with fine threads that allow micrometer-level adjustments. This component is integrated into leveling feet or foundation pad assemblies to compensate for uneven floors, settle loads evenly, and maintain operational alignment of equipment.

Working Principle

The adjustment bolt operates on the screw thread principle, where rotation of the bolt causes linear displacement along its axis. When turned clockwise, the bolt extends downward, lifting the machine; counterclockwise rotation retracts it, lowering the machine. This creates a precise, adjustable support point that distributes weight and corrects leveling deviations.

Materials

Typically manufactured from medium-carbon steel (e.g., Grade 5 or 8.8), stainless steel (AISI 304/316 for corrosion resistance), or alloy steel. May include zinc plating, hot-dip galvanizing, or other coatings for protection.

Frequently Asked Questions

How do I select the right adjustment bolt for my machine?

Consider load capacity, thread size, material compatibility with environment, and required adjustment range. Consult engineering specifications for torque and preload requirements.

Can adjustment bolts be reused?

Yes, if undamaged and within tolerance. Inspect threads for wear or deformation and replace if signs of fatigue or corrosion appear.
