Detailed Engineering Specifications

Built to exacting engineering tolerances, this M7x132mm hex head cap screw features a nominal diameter of 7mm and a total length of 132mm. The robust carbon steel construction ensures excellent tensile strength and durability, making it suitable for applications requiring high clamping force and resistance to shear stress. The precisely machined hex head, with a nominal width of 7mm, allows for efficient torque application using standard hex drivers, preventing over-tightening and ensuring consistent preload. Its material composition provides a good balance of strength and ductility for general industrial use where moderate corrosion resistance is acceptable.

Installation Procedure

1. Select the appropriately sized hex wrench or socket that fully engages the 7mm hex head. 2. Position the cap screw through the mating components, ensuring threads are aligned with the receiving hole or nut. 3. Apply steady torque to tighten the screw until the desired clamping force is achieved, avoiding over-tightening.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized or worn hex wrench, leading to cam-out and potential stripping of the hex head.Always use a properly sized and well-maintained hex wrench or socket that provides a snug fit.
Applying excessive torque, which can lead to thread damage, screw fracture, or deformation of mating parts.Refer to torque specifications for the application and material if available, or tighten to a firm, secure fit without overexertion.

Common Applications

  • Machinery assembly and repair
  • Structural framework connections
  • Automotive and heavy equipment manufacturing

⚠️ Engineering Warnings

  • Carbon steel is susceptible to corrosion in moist or chemically aggressive environments; consider protective coatings or alternative materials for such conditions.
  • Ensure the thread pitch and diameter are compatible with the intended mating component to prevent cross-threading or fastener failure.
