Detailed Engineering Specifications

Designed for demanding industrial environments, this M16x29mm hex head cap screw is precision-machined from high-grade brass (CuZn39Pb3 or equivalent). Its material composition provides excellent resistance to corrosion from moisture, chemicals, and saltwater, making it ideal for marine, electrical, and outdoor applications. The robust hex head ensures secure torque application with standard tooling, while the M16 thread size and 29mm length offer versatile integration into various assemblies. With a head width of 12mm, it balances load distribution with clearance requirements. Brass's inherent non-sparking characteristic is critical for hazardous locations where ignitable vapors or dust may be present.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using steel fasteners in corrosive environments leading to premature failure.Utilize brass fasteners like this hex head cap screw for superior corrosion resistance.
Applying excessive torque, which can strip brass threads.Use a torque wrench and adhere to recommended torque values for brass fasteners to prevent thread damage.

Common Applications

  • Marine hardware and deck fittings
  • Electrical connectors and switchgear
  • Chemical processing equipment
  • Food processing machinery
  • Corrosive atmospheric conditions

⚠️ Engineering Warnings

  • Brass is a relatively soft metal; avoid excessive force during tightening to prevent thread stripping.
  • While brass offers good corrosion resistance, consult chemical compatibility charts for extreme chemical exposure.
