Detailed Engineering Specifications

Built to exacting engineering tolerances, this M13x107mm brass hex head cap screw features a nominal diameter of M13 and a substantial length of 107mm. The hex head measures 27mm across flats, facilitating secure torque application with standard tooling. Crafted from free-machining brass (e.g., C36000), it exhibits excellent machinability, good ductility, and inherent resistance to corrosion, especially in marine and chemical environments. This material's non-magnetic properties also make it suitable for sensitive electronic assemblies. The coarse thread pitch ensures ease of installation and good holding power in a variety of substrate materials.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the brass cap screw, which can strip the threads or deform the workpiece.Always use a torque wrench and adhere to the recommended torque values for the specific material and application.
Using the wrong size wrench, leading to slippage and potential damage to the hex head.Utilize a correctly sized wrench or socket to ensure a snug fit on the hex head.

Common Applications

  • Electrical connectors and terminals
  • Marine hardware and fittings
  • Decorative architectural elements
  • Corrosion-resistant assemblies

⚠️ Engineering Warnings

  • Brass is a relatively soft material; avoid excessive force during installation.
  • Not suitable for structural load-bearing applications where high tensile strength is critical. Consider steel or stainless steel alternatives.
