Detailed Engineering Specifications

A proven choice for industrial professionals, this M13 x 118mm Brass Hex Head Cap Screw is engineered for reliable performance in demanding environments. The M13 metric thread size ensures compatibility with standard tapped holes and nuts, while the 118mm length provides ample engagement for secure fastening. Constructed from high-quality brass, it exhibits excellent corrosion resistance, particularly against moisture and certain chemicals, and is inherently non-magnetic, making it suitable for sensitive electronic or marine applications. The 10mm hex head width allows for standard tooling for efficient installation and removal. Its ductility also offers a degree of self-lubrication, reducing galling during assembly.

Installation Procedure

1. Ensure mating threads are clean and free from debris. 2. Hand-thread the cap screw to verify alignment and prevent cross-threading. 3. Tighten the cap screw using an appropriate wrench or socket to the recommended torque specification, avoiding over-tightening which can strip threads or deform the material.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during tightening, leading to thread damage or deformation of the brass head.Always consult or determine the appropriate torque specification for brass fasteners and use a torque wrench for precise application.
Installing in an environment with aggressive chemicals or galvanic corrosion risks without considering compatibility.While brass offers good corrosion resistance, verify its suitability for the specific chemical environment. Consider isolation washers if galvanic corrosion is a concern.

Common Applications

  • Electrical connectors and equipment in corrosive environments
  • Marine hardware and fixtures
  • Architectural and decorative applications requiring corrosion resistance

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid using in high-stress or shear applications where deformation is a risk.
  • Do not use with strong oxidizing agents or in extremely high-temperature environments where brass may degrade.
