Detailed Engineering Specifications

A high-performance industrial component, this M18 x 88mm brass hex head cap screw is manufactured to exacting standards. Its material composition, solid brass, provides excellent resistance to corrosion, particularly in marine, chemical, and humid environments. The nominal thread diameter is M18, with a total length of 88mm. The hex head measures 16mm across the flats, ensuring compatibility with standard M18 hex wrenches and drive tools. This design facilitates secure tightening and reliable load distribution. Brass's inherent non-sparking nature makes it a critical choice for hazardous locations where ignition sources must be strictly controlled.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a steel wrench on a brass screw, potentially damaging the head.Always use a brass or high-quality steel wrench that fits the hex head precisely to avoid stripping or deforming the fastener.
Over-tightening the brass screw, which can lead to thread damage or material deformation.Refer to torque charts for brass fasteners or use a torque wrench to apply the correct tension, avoiding excessive force.

Common Applications

  • Marine hardware and fittings
  • Electrical connectors and enclosures
  • Chemical processing equipment
  • Food and beverage machinery

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid applications requiring extreme tensile strength or shear resistance.
  • Ensure compatibility with the mating material to prevent galvanic corrosion if used in a dissimilar metal assembly.
