Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this M12x108mm hex head cap screw is crafted from high-grade brass, ensuring excellent machinability, natural corrosion resistance, and non-sparking properties. The M12 metric thread pitch provides secure engagement, and the nominal 108mm length allows for joining of thicker materials. The 11mm hex head offers a broad bearing surface for standard socket or wrench engagement, facilitating controlled torque application. Ideal for applications where galvanic corrosion is a concern, such as marine hardware, electrical connections, and architectural fittings.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong tool size, leading to cam-out and damaged hex heads.Always use the correctly sized socket or wrench to ensure full engagement with the hex head, preventing damage and enabling proper torque application.
Over-tightening brass fasteners, which can lead to thread galling or stripping.Apply torque gradually and use a torque wrench if precise load is critical. Brass is softer than steel and requires careful consideration of tightening limits.

Common Applications

  • Marine hardware and fittings
  • Electrical connections and grounding
  • Decorative architectural elements
  • Corrosion-resistant machinery assemblies

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in certain aggressive environments; verify material compatibility for extreme conditions.
  • While non-sparking, avoid using in environments with explosive atmospheres where static discharge could still be a hazard.
