Zinc Plated Carbon Steel Thumb Screw – High-Collar & Straight Knurls for Vibration Resistance

Product Overview

Our Zinc Plated Carbon Steel Thumb Screw combines rugged durability with intelligent design to tackle high-vibration environments. Featuring a high-collar spacer and straight knurled grip, this screw ensures secure, tool-free adjustments in automotive, industrial machinery, and outdoor equipment. The zinc-plated carbon steel construction offers corrosion resistance, while the knurled design enhances grip, making it ideal for applications where reliability and ease of maintenance are critical.

Key Features

✅ High-Collar Design

Spacer Function: Elevates the screw head to prevent contact with sensitive components and improve torque distribution.
Vibration Dampening: Reduces loosening in dynamic environments by absorbing shocks and oscillations.

✅ Straight Knurled Grip

Slip-Resistant Texture: Deep straight knurls ensure a firm grip, even with gloves or oily hands.
Ergonomic Handling: Wide thumb head for comfortable manual tightening/loosening.

✅ Zinc-Plated Carbon Steel

Corrosion Resistance: Trivalent zinc coating (RoHS-compliant) protects against rust in humid or outdoor conditions.
High Tensile Strength: Grade 8.8 carbon steel provides 800 MPa tensile strength for heavy-duty use.

✅ Versatile Compatibility

Metric Threads (M4–M10): Standard coarse/fine pitches (e.g., M6×1.0mm, M8×1.25mm).
Reusable Design: Maintains thread integrity after repeated adjustments.
