Threaded Stud: Load Capacity 500-5000 kg per stud

Component Specifications

Definition

A threaded stud is a precision-engineered cylindrical rod featuring continuous external threads along its entire length or on both ends. In adjustable leveling foot assemblies, it serves as the central connecting element that allows height adjustment through threaded engagement with mating components. Typically manufactured to tight dimensional tolerances, it provides reliable load-bearing capacity while enabling fine-tuning of machine leveling.

Working Principle

The threaded stud operates on the screw thread principle, where rotational motion converts to linear displacement. When turned within threaded receptacles of the leveling foot assembly, it extends or retracts to adjust height, maintaining stability through continuous thread engagement and proper preload.

Materials

Common materials include: Carbon steel (Grade 5, Grade 8), Stainless steel (304, 316), Alloy steel (4140, 4340), Brass, Aluminum alloys. Surface treatments: Zinc plating, Hot-dip galvanizing, Phosphate coating, Chrome plating.

Frequently Asked Questions

What is the difference between a threaded stud and a bolt?

A threaded stud has threads on both ends without a head, while a bolt has a head on one end and threads on the other. Studs are typically used where components need to be assembled from both sides.

How do I select the right threaded stud for my leveling foot assembly?

Consider load requirements, environmental conditions (corrosion resistance), thread compatibility with mating parts, required adjustment range, and material specifications based on application demands.

Can threaded studs be customized for specific applications?

Yes, they can be customized in terms of material, length, diameter, thread type, surface treatment, and special features like reduced shanks or special ends.
