Detailed Engineering Specifications

Specified by design engineers worldwide, this M11x55mm Hex Head Cap Screw is manufactured from Titanium Grade 5 (Ti-6Al-4V), renowned for its excellent biocompatibility, high tensile strength (up to 950 MPa), and exceptional resistance to corrosion in aggressive environments. The M11 thread form ensures secure fastening, while the 55mm length and 25mm head width provide ample bearing surface and torque application capability. Its low density (4.43 g/cm³) makes it ideal for weight-sensitive applications. Designed for use in aerospace, medical implants, marine, and chemical processing industries where performance and longevity are paramount.

Installation Procedure

1. Ensure mating threads are clean and free from debris. 2. Apply a suitable lubricant or anti-seize compound to the threads if recommended for the application. 3. Insert the screw and engage threads by hand for several turns to prevent cross-threading. 4. Tighten the screw to the specified torque using an appropriate calibrated torque wrench.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, potentially stripping threads or deforming the mating material.Always use a calibrated torque wrench and adhere to the manufacturer's or engineering specifications for torque values.
Using the wrong tool size, which can damage the hex head and compromise torque application.Select the correct size hex bit or wrench that fits snugly into the screw head to ensure proper engagement.
Not cleaning mating surfaces, which can lead to inconsistent clamping force and potential galling.Thoroughly clean both the screw threads and the internal threads of the mating component before assembly.

Common Applications

  • Aerospace structural components
  • Medical implants and surgical instruments
  • Marine and offshore equipment
  • High-performance automotive assemblies
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Titanium Grade 5 can gall if not properly lubricated or if threads are damaged during installation.
  • Always follow specific torque specifications to prevent fastener failure or damage to the assembly.
