Professional Applications & Engineering Value

This M4 set screw with brass tip delivers exceptional engineering value in applications requiring secure fastening without surface damage. The 18-8 stainless steel construction provides excellent corrosion resistance for longevity in industrial environments, while the soft brass tip prevents galling and protects precision components during assembly. The Class 6g thread fit ensures precise engagement in metric coarse thread applications, maintaining consistent clamping force in machinery, automotive components, and electronic enclosures. The headless design with 2mm hex drive allows for flush mounting in space-constrained applications, making it ideal for securing collars, gears, and pulleys where protrusion must be avoided. This combination of materials and precision engineering solves critical challenges in assembly processes requiring both security and surface protection.
