S-92785A542 1/4"-28 x 1/2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for tight, reliable fastening in demanding applications
• Excellent corrosion resistance provided by 18-8 Stainless Steel construction for long-term durability in harsh environments
• Precise component positioning enabled by the 90° cone point that bites into surfaces securely
• High torque capability with 1/8" hex drive for secure installation without head protrusion
• Enhanced fatigue resistance from Rockwell B80 hardness for sustained performance under vibration
• Fine thread engagement with 1/4"-28 UNF specification for improved adjustment precision
• Regulatory compliance assurance meeting ASME B18.3 standards and environmental regulations

Professional Applications & Engineering Value

This high-performance set screw delivers exceptional engineering value in applications requiring precise component positioning and reliable torque transmission. The 18-8 Stainless Steel construction provides outstanding corrosion resistance, making it ideal for machinery, automotive assemblies, and industrial equipment exposed to moisture or chemicals. The 90° cone point design ensures maximum bite into mating surfaces, preventing slippage in high-vibration environments. With its Class 3A thread fit and 1/4"-28 UNF fine threads, this hex headless screw offers superior clamping force and precise adjustment capabilities. The Rockwell B80 hardness maintains structural integrity under repeated stress cycles, while the 1/8" hex drive allows for efficient installation in confined spaces where traditional headed fasteners cannot be used.

Specification Summary & Compliance

This precision set screw features Class 3A thread fit tolerance for superior engagement and meets ASME B18.3 manufacturing specifications. The 1/4"-28 UNF fine thread configuration ensures precise adjustment with excellent holding characteristics. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance management. The combination of 18-8 Stainless Steel material, Rockwell B80 hardness, and 90° cone point angle delivers consistent performance across industrial applications requiring reliable, corrosion-resistant fastening solutions.
