- Full compliance with RoHS 3 and REACH regulations, meeting international environmental and safety standards.
Professional Applications & Engineering Value
This 10-32 UNF left-hand thread screw is engineered to address critical challenges in machinery, automotive, and electronics assembly where reverse threading prevents loosening under counter-clockwise motion. The 18-8 Stainless Steel material offers excellent resistance to oxidation and chemicals, extending service life in humid or corrosive settings. Its fully threaded design and fine thread spacing maximize grip strength in thin materials, while the rounded button head with hex drive ensures flush mounting and high torque application without stripping. Ideal for securing components in conveyors, rotating equipment, and precision instruments, this screw delivers reliability where standard right-hand threads are unsuitable.
Specification Summary & Compliance
Manufactured to UNF fine thread standards with Class 2A thread fit for consistent dimensional accuracy. The screw features a 0.361" head diameter, 1/2" length, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring adherence to restricted substance directives. Threading is precision-cut for optimal engagement, supporting ASME/ANSI specifications for industrial fasteners.
