Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Component Spacing & Structural Support: Hexagonal standoff screws maintain precise distances between PCBs, electronics, or mechanical parts to prevent short circuits and ensure airflow.
  • Versatile Threaded Attachment: Double-ended male and female threads (M2 to M4) allow secure, adjustable mounting on components like circuit boards, machinery, or industrial hardware.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With corrosion-resistant stainless steel and durable brass construction, ensure long-lasting performance in harsh environments. Stainless steel offers 30% better corrosion resistance than carbon steel*, making it ideal for industrial and outdoor applications.

  • 2. Hexagonal Interactive Design for Easy Installation

    • With a hexagonal design, easily adjust and secure components using standard hex wrenches. 20% faster installation compared to round-headed screws*, reducing assembly time in electronics and mechanical projects.

  • 3. Customizable Performance Parameters

    • Customizable lengths (15mm to 25mm) and thread sizes (M2 to M4) accommodate diverse spacing and compatibility needs. Supports up to 10kg load capacity*, ensuring structural stability in PCB assemblies and heavy-duty equipment.

  • 4. Versatile Scenario Solutions

    • Designed for precise PCB assembly, preventing short circuits and ensuring airflow. Ideal for both home electronics projects and commercial manufacturing setups*, adapting to compact or large-scale applications.

  • 5. Industrial-Grade Certification Standards

    • Stainless steel variants meet ISO 3506 standards for corrosion resistance and durability*, ensuring reliability in demanding environments like automotive and medical engineering.
