Non-standard Oxidized Tapping Screw 3/4 Inch High Grade Button Head Torx Half Thread Screw with Flat Washer

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Tapping & Fastening: Designed to create threads in materials while securing joints, ideal for applications requiring precise fastening in metal, wood, or plastic.
  • Versatile Head & Drive: Features a button head for low-profile installation and a Torx drive for secure, high-torque applications, reducing cam-out risk during use.

Key features

  • 1. Advanced Material Technology

    • With zinc-flake coated steel and corrosion-resistant finishes (e.g., black oxide, cadmium plated), you can ensure long-lasting durability in harsh environments, outperforming standard screws prone to rust or degradation*.

  • 2. Precision Interactive Design

    • The button head design with cross recessed (Phillips) drive allows for secure, flush mounting in tight spaces, simplifying assembly in furniture, electronics, or automotive projects compared to protruding head types*.

  • 3. Versatile Performance Parameters

    • The half-thread feature and M3.5/M3.9 thread sizes enable precise fastening in materials like wood or plastic without over-threading, offering 20% faster installation than fully threaded screws in certain applications*.

  • 4. Custom Scenario Solutions

    • As a non-standard tapping screw, you can create threads on-the-go for custom projects, eliminating the need for pre-drilling and outperforming standard screws in irregular or hard-to-reach applications*.

  • 5. Certified Reliability

    • Compliance with BS, DIN, and ANSI standards ensures consistent performance across global projects, surpassing uncertified alternatives in quality and safety*.

Product details

Non-standard Oxidized Tapping Screw 3/4 Inch High Grade Button Head Torx Half Thread Screw with Flat Washer

Supplier's note

  1. Technical Breakthroughs:

    • Material Innovation: C1022 steel provides 15% higher tensile strength than standard A36 steel.
    • Corrosion Resistance: Zinc-flake coatings offer 2x longer lifespan in saline environments compared to plain finishes.
    • Thread Design: Half-thread geometry reduces material strain by 25% in thin substrates.

  2. Optimal Version Selection:

    • Base Model: Ideal for DIY or light industrial use where cost efficiency is prioritized.
    • Advanced Model: Recommended for automotive or marine projects needing corrosion resistance and extended length options.
    • Pro Model: Tailored for aerospace or heavy machinery applications requiring extreme durability and custom specifications.

With the Pro Model’s cadmium plating, you can ensure corrosion resistance triple the industry standard, enabling safe handling of chemicals in industrial settings. Paired with its aerospace-grade steel, this creates a 30% stronger bond in high-stress assemblies.
