• Precise component positioning with the 90° cone point design, ideal for creating permanent, non-slip assemblies.
• Easy installation in confined spaces thanks to the headless and hex drive design, allowing for efficient tool access.
• Guaranteed dimensional accuracy and interchangeability, manufactured to meet ASME B18.3 specifications.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental standards.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw is engineered to solve critical challenges in precision assembly and machinery. Its Class 3A UNF fine threads and 90° cone point ensure maximum grip and alignment, preventing loosening under vibration—common in automotive, aerospace, and heavy equipment. The headless hex drive design allows installation in tight spaces where standard screws can't fit, while the alloy steel construction and Rockwell C45 hardness provide the strength needed for high-stress applications. Ideal for securing gears, pulleys, and collars, this set screw delivers reliable, long-term fastening without compromising on environmental compliance or performance.

Specification Summary & Compliance

This set screw features a 1/4"-28 UNF fine thread with Class 3A tolerance for precise fit, a 7/16" length, and 1/8" hex drive. It is manufactured in accordance with ASME B18.3 standards and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict industry and environmental requirements.
