Professional Applications & Engineering Value

This Grade 2 Titanium shoulder screw is engineered to address common challenges in precision machinery, aerospace, and medical equipment. The 8-32 UNC thread with a Class 3A fit provides a secure, high-tolerance connection that resists loosening under vibration, critical for dynamic assemblies. The 3/16" shoulder diameter and precisely machined shoulder length act as a reliable pivot or spacer, ensuring accurate alignment of moving parts like gears, bearings, and linkages. Made from titanium, it offers an excellent strength-to-weight ratio and inherent corrosion resistance, eliminating the need for additional coatings and reducing long-term maintenance in demanding environments. The socket head with knurled texture enhances tool engagement, preventing cam-out during torque application and streamlining assembly processes on the production line.

Specification Summary & Compliance
