High-Quality M12 & M20 Brass-Plated Flat & CSK Head Machine Screws
Product Overview
Machine screws are specialized fasteners designed for precision joining of components. Defined by ASME as having diameters no larger than 0.75 inches, these screws feature uniform threading that maintains consistent size from top to bottom, distinguishing them from tapered thread alternatives.

The distinction between cross-head flat-head screws and cross-head round-head screws lies in their heads: one is countersunk, with a flat, funnel-shaped head.

Primarily employed for securing thin plates, the countersunk head fully engages within the component being fastened. The countersunk surface aligns flush with the fastened surface, enhancing the product's aesthetic appeal. The other is a pan head, typically used in applications requiring greater load-bearing capacity. The larger pan head provides superior holding strength for the fastened product. Additionally, its larger head facilitates easier assembly.

Key Advantages
  • Compact size enables versatile applications across numerous products and surfaces
  • Available in multiple high-performance materials including stainless steel and aluminum
  • Stainless steel variants offer exceptional rust and corrosion resistance
  • Aluminum options provide lightweight solutions without compromising durability
Brass Maintenance Guidelines
  • Store in dry environments away from acidic substances
  • Clean regularly with soft flannel and specialized cleaning agents
  • Apply protective coatings through electroplating or hot plating methods
  • Use copper anti-coloring agents for enhanced corrosion protection
Industrial Applications
Brass components are extensively used in mechanical systems including bearings, gears, fasteners, valves, and automotive parts. Their excellent workability and mechanical properties make them ideal for plumbing fittings, architectural elements, and decorative applications in residential and commercial settings.
Stainless Steel Maintenance
  • Preserve the natural protective film through gentle cleaning methods
  • Avoid abrasive materials that could damage the surface
  • Use appropriate chemical treatments for humid environments
  • Rinse thoroughly after chemical application and dry completely
