Detailed Engineering Specifications

Trusted by engineers across multiple sectors, this M8 x 48mm brass hex head cap screw features a nominal diameter of M8 and a length of 48mm, with a substantial 20mm head width for efficient torque application. Manufactured from high-grade brass (typically UNS C36000 or similar), it provides excellent resistance to corrosion, especially in marine and humid environments. Its non-magnetic nature is critical for applications sensitive to magnetic fields, and its inherent electrical conductivity makes it suitable for grounding or conductive assemblies. The hex drive allows for secure fastening with standard wrenches.

Installation Procedure

1. Select an appropriately sized wrench or socket that fits snugly onto the hex head. 2. Thread the cap screw into the pre-tapped hole or mating component by hand to prevent cross-threading. 3. Tighten the screw to the required torque specification using the wrench, ensuring a secure connection without over-stressing the material.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Cross-threading the screw by forcing it into the hole.Always start threading the screw by hand to ensure it is properly aligned before applying torque.
Using excessive force, leading to galling or stripping of the threads.Apply torque gradually and stop when the fastener is snug. Consult torque charts for brass fasteners if precise tension is required.

Common Applications

  • Marine hardware and fittings
  • Electrical connections and grounding
  • Decorative architectural elements
  • Plumbing assemblies

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in aggressive environments; consult application-specific chemical resistance data.
  • While less prone to galling than stainless steel, proper lubrication and torque control are still recommended for optimal performance.
