Detailed Description

Overview

Our Zinc Plated Stepped Shoulder Pins (Pivot Stud Bolts) are multi-functional precision components engineered for pivoting assemblies, structural guiding, and accurate axial positioning. Featuring a threaded mounting stud on top, an integrated enlarged flange/collar in the middle, and a smooth ground cylindrical shaft on the bottom, these bolts provide a combination of secure thread fastening and smooth rotational movement.

Machined from high-grade carbon steel or alloy steel, each pin undergoes precision turning to guarantee strict concentricity between the thread and shaft body, complemented by a protective zinc plating against rust and corrosion.

Key Features & Advantages

  • Integrated Stop Flange: The solid shoulder collar eliminates the need for separate washers, providing a rigid mechanical stop and even load distribution.
  • Smooth Ground Bearing Shaft: The unthreaded cylindrical portion serves as a low-friction bearing or guide pin for rotating arms, levers, and sliding linkages.
  • High Concentricity & Shear Strength: Solid cold-formed or CNC lathe construction withstands high transverse shear loads without bending.
  • Corrosion Protection: Electro-galvanized zinc coating delivers superior resistance to moisture, shop oils, and environmental wear.
