Professional Applications & Engineering Value

This 10-32 UNF set screw is engineered to address critical challenges in precision assembly and machinery. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications in moist or chemically aggressive environments, such as marine equipment, food processing machinery, and outdoor industrial fixtures. The extended tip design increases the bearing surface, reducing point loading and preventing damage to softer shaft materials, which is vital for maintaining alignment in pulleys, gears, and collars. Combined with the fine thread spacing and Class 3A thread fit, this set screw delivers vibration-resistant performance, ensuring that components remain securely locked in place even under dynamic loads. Its headless and hex drive configuration allows for a clean, unobtrusive installation, ideal for use in compact assemblies where space is at a premium.

Specification Summary & Compliance

This set screw adheres to tight dimensional tolerances, including a Class 3A thread fit for superior precision and a tip diameter tolerance of -0.007" to 0. Thread specifications follow the UNF (Unified National Fine) standard with a 10-32 thread size and right-hand direction. Manufacturing and quality are governed by ASME B18.3. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated markets and commitment to environmental safety.
