Professional Applications & Engineering Value
Engineered for demanding applications, these A286 stainless steel rounded head screws deliver critical reliability where failure is not an option. The high-strength material and Rockwell C24 hardness directly combat issues of material fatigue and galling in high-vibration settings, such as aerospace components, automotive assemblies, and heavy machinery. The Torx T25 drive offers superior torque transfer compared to traditional drives, minimizing tool slippage and head stripping, which is vital for precision assembly lines. Combined with UNC coarse threads and a Class 2A fit, these screws ensure faster installation and a secure hold in a wide range of materials, reducing assembly time and improving overall structural integrity in corrosive or high-stress environments.
Specification Summary & Compliance
This fastener features a 10-24 UNC thread size with a coarse spacing and a Class 2A thread fit, ensuring dimensional accuracy and interchangeability. The screw is fully threaded and measures 1" in length. Manufacturing and material compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making these screws suitable for use in regulated markets and environmentally conscious projects.
