The most corrosion-resistant oval-tip set screws we offer. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. With a rounded tip, these screws won't dig into surfaces like cone- and cup-tip screws do. This makes them ideal for when you need to adjust screws frequently while avoiding scratches on mating parts. Since the round tip makes contact at an angle, they're good for surfaces with U- or V-shaped grooves.

These set screws make the finest adjustments of any we sell. With ultra-fine threads, these screws are found on measuring devices and photonic equipment, where minute adjustments and tight tolerances are critical. They also fine-tune sensors on automated equipment and ensure repeatable positioning on jigs and fixtures. Generally used in dry, controlled environments, the alloy steel tip can oxidize in wet or outdoor environments.
