Detailed Engineering Specifications

Purpose-built for heavy-duty applications, this M16 x 90mm brass hex head cap screw features a nominal diameter of M16 and a length of 90mm, with a head width of 9mm for substantial torque application. Manufactured from high-grade brass (typically UNS C36000 or equivalent), it exhibits excellent resistance to corrosion, particularly in marine and chemical environments, and is inherently non-magnetic, making it suitable for electrical applications where ferrous materials are undesirable. The brass material provides good tensile strength for its class and a pleasing aesthetic for exposed components.

Installation Procedure

1. Select the appropriate wrench or socket to fit the 9mm hex head. 2. Ensure the mating threads are clean and free of debris. 3. Insert the screw into the pre-drilled or tapped hole. 4. Tighten the screw to the required torque specification, avoiding overtightening to prevent thread stripping or material deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a wrench that does not properly fit the hex head, leading to stripping.Always use a properly sized socket or wrench that fully engages with the hex head to ensure even torque distribution and prevent damage.
Applying excessive force, causing the brass threads to strip or the screw to break.Refer to torque charts for brass fasteners or apply moderate, consistent torque. Brass is softer than steel, requiring a more delicate approach to tightening.

Common Applications

  • Marine hardware and fittings
  • Electrical grounding and bonding components
  • Decorative architectural elements
  • Chemical processing equipment
  • Food processing machinery

⚠️ Engineering Warnings

  • Brass may not be suitable for high-stress structural applications where steel fasteners are typically required.
  • While corrosion-resistant, brass can react with certain aggressive chemicals. Consult compatibility charts if unsure.
