Product Overview

Our RoHS-Certified Metric Phillips Flat Head Step Shoulder Screws combine ultra-low profile design with precision engineering for applications demanding minimal protrusion, exact alignment, and reliable fastening. Crafted from high-grade alloy steel with a corrosion-resistant finish, these screws are ideal for electronics, medical devices, aerospace, and compact machinery where space optimization and compliance are critical.

Key Features

✅ Ultra-Low Profile Flat Head

• Space-Saving Design: Sits nearly flush with surfaces (head height <1mm) to avoid interference in tight spaces.
• Phillips Drive (PH1/PH2): Compatible with standard screwdrivers or automated tools for quick installation.

✅ Step Shoulder Precision

• Unthreaded Shoulder: Provides precise alignment for bearings, bushings, or rotating components.
• Smooth Bearing Surface: Reduces friction and wear on mating parts.

✅ RoHS-Certified Materials

• Lead-Free Alloy Steel: Grade 8.8/10.9 tensile strength (up to 1,000 MPa) with black oxide or zinc-nickel plating.
• Corrosion Resistance: Withstands humidity, chemicals, and industrial environments.

✅ Customizable Metric Sizes

• Thread Sizes: M2–M8 (standard) or custom diameters.
• Shoulder Dimensions: Tailor diameter (2mm–12mm) and length (3mm–30mm) to your design.
