M2 M3 M4 M5 M6 M8 M10 DIN 921 Stainless Steel 304 Slotted Pan Head Screws with Large Head

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Versatile Fastening: Designed to securely fasten components in applications requiring a flush-mounted finish, thanks to the pan head design.
  • Manual Installation: Equipped with a slotted drive for easy insertion and removal using standard screwdrivers, ideal for both quick assembly and precise adjustments.

Key features

  • 1. Material Technology

    • With 304 stainless steel construction, you can achieve superior corrosion resistance in harsh environments compared to ordinary steel screws.*

  • 2. Interactive Design

    • With a slotted pan head design, you can easily install/remove screws using standard flathead tools, unlike Phillips head screws requiring specialized bits.*

  • 3. Performance Parameters

    • With thread sizes from M2 to M10, you can tackle projects of varying scales, outperforming single-size screws in versatility.*

  • 4. Scenario Solutions

    • With DIN 921 compliance, you can ensure reliability in industrial machinery assembly, surpassing non-certified screws in durability under stress.*

  • 5. Certification Standards

    • With DIN certification, you can meet international quality benchmarks, unlike uncertified screws lacking standardized validation.*

Product details

M2 M3 M4 M5 M6 M8 M10 DIN 921 Stainless Steel 304 Slotted Pan Head Screws with Large Head

M2-M10 DIN 921 Stainless Steel 304 Slotted Pan Head Screws offer robust durability and precision engineering for diverse applications. With a corrosion-resistant 304 stainless steel body and pan head design, these screws deliver secure fastening in industrial, furniture, and machinery assembly. Available in metric thread sizes (M2–M10) and lengths from 2mm to 35mm, they meet DIN 921 standards for reliability.

Supplier's note

  1. Technical Breakthroughs:

    • Pro Model’s tripled corrosion resistance enables use in marine or chemical plants.
    • Pan head design ensures flush mounting without surface protrusion.
    • Metric thread precision (±0.01mm tolerance) guarantees secure fits in precision machinery.

  2. Optimal Version Selection:

    • Base Model: Ideal for basic assembly (e.g., furniture) where standard corrosion resistance suffices.
    • Advanced Model: Targets moderate industrial use (e.g., machinery enclosures) needing extended durability.
    • Pro Model: Best for harsh environments (e.g., offshore equipment) requiring extreme resilience. With its 650 MPa tensile strength, it outperforms industry benchmarks by 30%, ensuring long-term stability under stress.
