Professional Applications & Engineering Value

Engineered for precision and durability, this 00-90 Torx Plus button head screw solves critical challenges in electronics, aerospace, and medical device assembly. The 18-8 Stainless Steel construction combined with a passivated finish provides excellent resistance to oxidation and chemical exposure, preventing failure in corrosive environments. The Torx Plus drive (IP2 size) minimizes tool slippage, allowing for higher torque application and reducing assembly errors and component damage. Its fine thread and fully threaded design ensure secure fastening in delicate or thin-section materials, making it an ideal industrial fastener for applications where space is constrained and reliability is non-negotiable.

Specification Summary & Compliance

This screw features a 00-90 UNS fine thread with a Class 2A thread fit for consistent dimensional accuracy. It is manufactured in compliance with the ASME B18.3 standard, ensuring interchangeability and performance. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for global use.
