Detailed Engineering Specifications

Specified by design engineers worldwide, this M17 x 135mm brass hex head cap screw features a nominal diameter of M17, an overall length of 135mm, and a head width of 10mm. Manufactured from solid brass (typically UNS C26000 or C36000), it provides excellent resistance to atmospheric and water corrosion, making it suitable for marine, electrical, and decorative applications. The inherent non-magnetic properties and good electrical conductivity of brass are further advantages. This screw conforms to relevant ISO or DIN standards for metric fasteners, ensuring interchangeability and reliable performance in critical assemblies.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening brass fasteners, which can lead to thread stripping or deformation.Utilize a torque wrench set to the manufacturer's recommended torque specification for the specific brass alloy and thread size.
Using brass screws in high-stress structural applications where steel or stainless steel is recommended.Select fastener materials based on load-bearing requirements, environmental exposure, and potential for galvanic corrosion. Brass is not suitable for primary structural integrity.

Common Applications

  • Electrical connectors and busbars
  • Marine hardware and fittings
  • Decorative architectural elements
  • Plumbing and water systems

⚠️ Engineering Warnings

  • Brass can undergo galvanic corrosion when in direct contact with dissimilar metals in an electrolyte. Ensure proper material selection or isolation.
  • Avoid abrasive cleaning methods that can scratch the polished brass surface and diminish its aesthetic qualities.
