Professional Applications & Engineering Value

This 5/16"-18 UNC set screw in 316 Stainless Steel is engineered to address critical industrial challenges, such as corrosion in marine, chemical, and food processing equipment. Its headless design with a hex drive allows for flush mounting in tight spaces, while the Class 3A thread fit and coarse thread spacing deliver superior holding power against vibration and dynamic loads. The extended tip enhances grip on shafts and collars, preventing slippage in high-torque applications. Ideal for securing pulleys, gears, and knobs, this screw provides long-term reliability and reduces maintenance downtime in demanding environments.
