Product Overview

Our Customized Stainless Steel Step Shoulder Screws are engineered for applications demanding precision alignment, corrosion resistance, and tailored dimensions. Featuring a plain finish (natural passivated surface), a smooth unthreaded shoulder, and customizable lengths from 1mm to 500mm, these screws are ideal for medical devices, marine equipment, aerospace systems, and industrial machinery where exact tolerances and durability are critical.

Key Features

✅ Stainless Steel 304/316 Construction

• Corrosion Resistance: Withstands harsh environments, including saltwater, chemicals, and high humidity.
• High Tensile Strength: 515 MPa (304) or 620 MPa (316) for load-bearing and dynamic applications.

✅ Plain Passivated Finish

• Natural Protection: Passivation process enhances stainless steel’s innate corrosion resistance without coatings.
• Clean Aesthetic: Ideal for medical or food-grade applications requiring non-coated surfaces.

✅ Precision Step Shoulder Design

• Unthreaded Shoulder: Ensures smooth alignment of bearings, bushings, or rotating components.
• Custom Dimensions: Shoulder diameter (2mm–50mm), thread length, and total length (1mm–500mm).

✅ Versatile Applications

• Medical: Sterilizable screws for surgical tools, implants, and imaging equipment.
• Marine/Aerospace: Corrosion-resistant fastening for ship fittings, avionics, and satellites.
• Industrial: Rotational components in robotics, CNC machines, and conveyor systems.
• Electronics: Low-profile fasteners for PCB mounts and micro-devices.

✅ Certified Quality

• Compliant with ISO 3506 (stainless steel), RoHS, and ISO 9001 standards.
