Detailed Engineering Specifications

Built to exacting engineering tolerances, this M23 x 85mm hex head cap screw is manufactured from high-grade brass, renowned for its excellent corrosion resistance, particularly in marine and humid environments. The M23 metric thread size ensures compatibility with standard M23 nuts and tapped holes, while the 85mm length provides ample thread engagement for secure assembly. The 14mm hex head offers a substantial bearing surface for torque application, facilitating consistent and reliable tightening. Brass's inherent non-magnetic properties and good electrical conductivity also make it suitable for specific electrical and instrumentation assemblies where these characteristics are critical.

Installation Procedure

1. Clean both the screw threads and the mating thread or nut to remove any debris or contaminants. 2. Apply a suitable lubricant or anti-seize compound to the threads if recommended for the specific application and material combination. 3. Insert the cap screw into the designated hole and thread it by hand to ensure proper alignment and prevent cross-threading. 4. Tighten the cap screw using an appropriate wrench or socket, applying torque gradually and evenly to the specified torque value for the application and material. Avoid over-tightening.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Cross-threading the fastener due to misalignment or forcing the screw.Ensure threads are clean and aligned before starting to turn. If resistance is met, back out the screw and re-align.
Using excessive force, leading to stripped threads or fastener breakage.Adhere to recommended torque specifications for the material and application. Use a torque wrench for precision.
Using the wrong size tool for the hex head, resulting in damage to the head.Always use the correctly sized hex socket or wrench for the 14mm head width to ensure proper grip and prevent slippage.

Common Applications

  • Marine hardware and fittings
  • Electrical connectors and enclosures
  • Decorative architectural elements
  • Plumbing and water systems
  • Instrumentation and control panels

⚠️ Engineering Warnings

  • Brass is a softer metal than steel; avoid using excessive force which can strip threads or damage the head.
  • While corrosion-resistant, brass can react with certain chemicals. Consult compatibility charts for specific environments.
  • Ensure the mating thread or nut is also suitable for the operating environment and load requirements.
