Detailed Engineering Specifications

Built to exacting engineering tolerances, this M22 x 149mm hex head cap screw is manufactured from high-grade brass (ASTM B16/B16M). The material's inherent ductility and excellent corrosion resistance, particularly in marine and chemical atmospheres, make it a superior choice for applications requiring non-magnetic properties and aesthetic appeal. The M22 thread provides substantial tensile strength and load-bearing capacity, with a nominal head width of 34mm for secure torque application. Its 149mm length ensures adequate engagement for thicker materials or assemblies.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the brass screw, which can lead to thread stripping or deformation of the fastener.Always use a torque wrench and adhere to recommended torque specifications for brass fasteners to prevent damage.
Using the wrong thread pitch or diameter, resulting in a loose or non-functional connection.Verify the M22 thread specification and ensure it matches the intended mating component precisely.

Common Applications

  • Electrical connections and grounding hardware
  • Marine hardware and fittings
  • Decorative and architectural installations
  • Corrosion-prone environments

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in highly aggressive environments; select fasteners appropriate for the specific chemical exposure.
  • Avoid using brass fasteners in applications requiring extreme shear strength or impact resistance where steel may be more suitable.
