Professional Applications & Engineering Value

This Grade 2 Titanium Shoulder Screw is engineered to address critical challenges in precision assemblies, such as misalignment, corrosion, and weight reduction without sacrificing strength. The 8-32 UNC coarse thread with Class 3A fit ensures tight, reliable fastening in dynamic environments, minimizing vibration-induced loosening. The 3/16" shoulder length provides an exact datum for rotating parts, bearings, or linkages, reducing wear and simplifying maintenance. With a Rockwell B80 hardness and 40,000 psi tensile strength, it supports high-stress applications in aerospace, medical devices, and robotics, where durability and regulatory compliance are paramount. The knurled head and hex drive further enhance installation reliability, making it a top choice for engineers seeking long-term performance in compact, critical assemblies.

Specification Summary & Compliance
