Professional Applications & Engineering Value

These 6-32 UNC T15 Torx A286 Stainless Steel Rounded Head Screws are engineered to address critical challenges in demanding applications such as aerospace, automotive, and electronics assembly. The A286 Stainless Steel provides excellent resistance to oxidation and high temperatures, while the 130,000 psi tensile strength and Rockwell C24 hardness prevent stripping and deformation under heavy loads. The T15 Torx drive minimizes wear on tools and fasteners, ensuring repeatable installations without cam-out. With a fully threaded coarse UNC design and Class 2A thread fit, these screws deliver rapid, secure fastening in materials where vibration resistance and precision are paramount, reducing downtime and maintenance costs in industrial settings.

Specification Summary & Compliance

These screws feature a 6-32 UNC coarse thread with Class 2A tolerance for precise fit and reliable performance. They are manufactured to high standards with a rounded button head, T15 Torx drive, and 1/4" length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring they meet stringent environmental and safety regulations for global industrial use.
