Detailed Engineering Specifications

A proven choice for industrial professionals, this M5 x 134mm Hex Head Cap Screw is manufactured from high-grade brass (typically UNS C36000 or equivalent) offering excellent corrosion resistance, particularly in marine and chemical environments, and is inherently non-magnetic. The M5 thread designation ensures compatibility with standard metric fittings, while the 134mm length provides substantial grip. The generous 20mm head width allows for secure tightening with standard hex tools, distributing load effectively to prevent material damage. Its ductility and malleability make it suitable for applications requiring some deformation or where precise fitting is critical.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force which can strip the brass threads or deform the head.Employ a torque wrench set to the appropriate specification for brass fasteners to ensure proper tension without damage.
Using the wrong size hex driver, leading to cam-out and potential damage to the fastener head.Always use the correct size hex driver that fits snugly into the recess of the hex head.

Common Applications

  • Marine and offshore equipment assembly
  • Electrical connectors and switchgear
  • Decorative and architectural fixtures
  • Food processing machinery
  • Corrosive environment applications

⚠️ Engineering Warnings

  • Brass is a softer metal than steel; avoid using in high-stress or load-bearing applications where deformation is not acceptable.
  • While corrosion-resistant, prolonged exposure to aggressive chemicals may degrade brass. Consult material compatibility charts for specific environments.
