Detailed Engineering Specifications

Manufactured under strict quality controls, this M19x79mm Brass Hex Head Cap Screw features a nominal diameter of M19 and a total length of 79mm, with a head width of 16mm. Constructed from high-grade brass (e.g., UNS C36000 or equivalent), it exhibits excellent machinability, inherent corrosion resistance against moisture and many chemicals, and good electrical conductivity. The hex head design allows for high-torque application with standard wrenches or sockets, ensuring a secure and reliable connection. Its non-magnetic properties make it suitable for sensitive environments.

Installation Procedure

1. Select the appropriate tool (e.g., socket wrench) that fits the 16mm hex head. 2. Thread the cap screw into the pre-tapped hole or nut, ensuring smooth engagement. 3. Tighten the screw to the required torque specification, using a torque wrench if necessary, to achieve a secure joint without over-stressing the material.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripped hex head corners.Always use a wrench or socket that precisely matches the 16mm head width for optimal grip and torque transfer.
Over-tightening, which can deform the brass and compromise the joint strength.Apply torque gradually and, for critical applications, use a calibrated torque wrench to adhere to design specifications.

Common Applications

  • Marine hardware and fittings due to excellent corrosion resistance.
  • Electrical conductivity applications and connectors.
  • Decorative or architectural fixtures where aesthetic appeal is important.

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in aggressive environments; consult material compatibility charts for specific applications.
  • While brass offers good strength, it is softer than steel; avoid using in high-stress structural applications where steel fasteners are recommended.
