Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 18-8 Stainless Steel oval head slotted screws address critical challenges in machinery assembly, electrical enclosures, and precision equipment. The passivated finish creates a protective oxide layer that significantly enhances corrosion resistance in humid or chemically aggressive environments. With fully threaded UNC coarse threads and Class 2A thread fit, these fasteners provide superior holding power while accommodating minor misalignments during installation. The oval head design offers an aesthetic flush finish while the slotted drive allows for traditional tool compatibility. Particularly valuable in maintenance operations and OEM manufacturing, these screws deliver reliable performance where corrosion resistance and mechanical integrity are paramount concerns.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC coarse thread profile (8-32 size). Complies with ASME B18.6.3 manufacturing specifications ensuring consistent quality and interchangeability. Meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) standards for hazardous substance restrictions. The 82° countersink angle and standardized oval head profile guarantee proper seating and uniform clamping force distribution across assembled components.
