Brass DIN 404 Screws

Comprehensive Overview of Premium Brass DIN 404 Screws

We are a specialised manufacturer and global supplier of precision-engineered Brass DIN 404 Screws, providing superior fastening solutions for applications requiring low-profile, high-strength connections with excellent corrosion resistance. Our DIN 404 screws are manufactured from C36000 Free-Cutting Brass, selected for its exceptional machinability, reliable mechanical performance, and outstanding environmental resistance. These screws feature the distinctive cheese head design with a slotted drive, characterised by their cylindrical head with a flat top and slightly rounded edges, providing a lower profile than pan head screws while maintaining a substantial bearing surface. With advanced manufacturing capabilities and rigorous quality control systems, we deliver brass DIN 404 screws that excel in precision engineering, electrical applications, and industrial equipment where space constraints and reliable performance are critical.


Brass DIN 404 Screws – Low-Profile Precision Fastening

Brass DIN 404 Screws are engineered for applications where a low-profile head is essential but a larger bearing surface than flat head screws is required. The cheese head design offers a unique combination of minimal protrusion and excellent load distribution, making these screws ideal for compact assemblies, precision instruments, and applications where clearance is limited. The inherent corrosion resistance of brass makes these screws particularly valuable in electrical, marine, and chemical environments where steel fasteners would deteriorate rapidly.

Frequently Asked Questions (FAQ)

Q1: What distinguishes cheese head screws from pan head screws?
Cheese head screws feature a cylindrical shape with a flat top and slightly rounded edges, providing a lower profile than pan head screws while maintaining a substantial bearing surface. The cheese head design offers a unique balance of low height and good load distribution, making it ideal for applications where space is limited but a flat head screw doesn’t provide sufficient bearing area. Pan head screws have a more rounded top profile and typically greater height.

Q2: Are brass DIN 404 screws suitable for high-vibration applications?
Yes, brass DIN 404 screws provide good performance in vibration applications due to their substantial bearing surface and reliable thread engagement. However, for extreme vibration environments, we recommend considering additional securing methods such as lock washers, thread locking compounds, or prevailing torque features. The cheese head design provides excellent clamp load distribution which helps maintain joint integrity under vibrational stresses.

Q3: What are the advantages of the slotted drive design?
The slotted drive design offers universal tool compatibility, simple manufacturing, and reliable performance. Unlike Phillips or Pozidriv drives that require specific driver sizes, slotted drives work with any appropriately sized flat-blade screwdriver. This makes DIN 404 screws particularly valuable for field service, maintenance applications, and situations where tool availability may be limited. The design also allows for easy visual inspection of drive condition.

Q4: Can DIN 404 screws be used in marine and chemical environments?
Yes, brass DIN 404 screws are excellent for marine and chemical environments, particularly when manufactured from naval brass (C46400). The material’s inherent corrosion resistance makes it suitable for saltwater exposure, high humidity, and chemical processing environments. Unlike plated steel fasteners that can fail when the plating is compromised, brass provides corrosion resistance throughout the material cross-section for long-term reliability in aggressive environments.

Q5: How do I select the appropriate screw length for precision applications?
For precision applications, screw length selection should consider exact material thickness, required thread engagement, and clearance requirements. The cheese head design requires attention to the head height when calculating total space requirements. We recommend selecting a length that provides full thread engagement in the receiving material (typically 1-1.5 times the diameter) while ensuring the head sits properly on the bearing surface. Our technical team can provide specific recommendations based on your application parameters.
