Professional Applications & Engineering Value

These 18-8 stainless steel shoulder screws are engineered to address critical alignment and durability challenges in industrial assemblies. The 3-48 UNC coarse thread and Class 3A fit ensure tight, reliable fastening with minimal backlash, while the precision shoulder provides a stable pivot or spacer in machinery, electronics, and automation equipment. The knurled head and 5/64" hex drive facilitate secure handling and installation, even in confined spaces. Made from corrosion-resistant stainless steel, these screws maintain integrity in moist or chemically aggressive settings, reducing maintenance needs and extending service life in applications like rotating assemblies, pivoting mechanisms, and precision instruments.

Specification Summary & Compliance
