Detailed Engineering Specifications

Built to exacting engineering tolerances, this M16 x 105mm hex head cap screw is manufactured from premium 304 stainless steel, renowned for its excellent corrosion resistance and moderate tensile strength. The M16 nominal diameter ensures substantial load-bearing capacity, complemented by a 105mm length for versatile application in thicker materials or where extended reach is required. The 26mm head width provides ample surface area for torque application via a standard wrench or socket, facilitating secure tightening and preventing galling. This grade of stainless steel offers good performance in a wide range of temperatures and is non-magnetic, making it suitable for environments prone to chemical exposure or requiring electrical non-conductivity.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size socket, leading to stripping the hex head.Always use a correctly sized 26mm socket to ensure proper engagement and prevent damage to the screw head.
Cross-threading the screw, damaging both the screw and the mating component.Start threading by hand for at least two full rotations to confirm proper alignment before applying any tool.
Overtightening, which can lead to thread deformation or material failure.Refer to application-specific torque charts or consult with a structural engineer to determine the correct tightening torque.

Common Applications

  • Structural steel connections
  • Marine and offshore equipment
  • Chemical processing machinery

⚠️ Engineering Warnings

  • Ensure the mating component is compatible with 304 stainless steel to prevent galvanic corrosion.
  • Always use appropriate personal protective equipment (PPE) during installation.
