Detailed Engineering Specifications

Built to exacting engineering tolerances, this M13x150mm hex head cap screw is fabricated from solid brass, renowned for its inherent corrosion resistance, particularly in marine and humid environments. The M13 thread size ensures robust load-bearing capacity, while the 150mm length provides significant reach for structural or deep-set applications. The 7mm head width allows for secure engagement with standard hex drivers, facilitating efficient assembly and disassembly. Brass's non-magnetic properties and excellent conductivity also make it suitable for electrical and electronic assemblies where interference must be minimized.

Installation Procedure

1. Ensure the mating threads are clean and free from debris. 2. Hand-thread the screw to confirm proper alignment and prevent cross-threading. 3. Tighten to the required torque specification using an appropriate hex driver, avoiding over-tightening to prevent damage to the brass material or the receiving component.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Cross-threading the screw during initial insertion.Always start by hand-threading the screw to ensure it engages the mating threads correctly before applying any tooling.
Over-tightening the brass screw, leading to deformation or stripping.Utilize a torque wrench to apply the specified torque for the application. Brass is softer than steel and requires less force.

Common Applications

  • Marine hardware and fittings
  • Electrical connectors and enclosures
  • Decorative architectural elements
  • Plumbing and HVAC systems

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in aggressive chemical environments; verify compatibility before use.
  • Avoid using in applications subject to extreme shock loads or high tensile stresses where a higher-strength alloy may be necessary.
