S-92432A460 1/4"-20 x 1 1/2" Set Screws

Key Features & Benefits at a Glance

• Enhanced Grip & Damage Prevention: Permanent swivel tip with 7.5° maximum angle distributes pressure evenly, preventing marring and providing a secure hold on delicate or hardened shafts.
• Superior Corrosion Resistance: Black-oxide finish on the alloy steel body offers improved protection against rust and oxidation in demanding industrial environments.
• High-Strength Durability: A Rockwell C45 hardness rating ensures exceptional resistance to wear, deformation, and loosening under high vibrational loads.
• Reliable & Repeatable Fastening: UNC coarse thread with a Class 2A fit allows for easy, quick assembly while maintaining consistent clamping force and alignment.
• Secure Installation in Confined Spaces: The headless design combined with a 1/8" hex drive enables installation in recessed or limited-clearance applications with standard tools.
• Optimized for High-Torque Applications: The robust alloy steel tip material and integrated swivel mechanism withstand high installation torque without failure.
• Global Compliance for Supply Chains: Meets RoHS 3 and REACH regulations, ensuring suitability for international industrial and OEM projects.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw is engineered to solve critical challenges in power transmission and motion control systems. Its permanent swivel tip is pivotal for applications involving pulleys, gears, and collars on hardened shafts, where a standard set screw could cause fretting, galling, or damage to the expensive component. The UNC coarse thread ensures rapid assembly and disassembly, which is vital for maintenance and adjustments in conveyor systems, motor assemblies, and heavy machinery. The combination of Rockwell C45 hardness and the corrosion-resistant black-oxide finish guarantees that the fastener maintains its clamping force and integrity in high-vibration, high-load environments, reducing the risk of unexpected downtime and component failure.

Specification Summary & Compliance

This set screw adheres to the UNC thread standard with a precise Class 2A thread fit for consistent dimensional accuracy. The manufacturing and material specifications ensure reliable performance in line with common industrial requirements. The product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I and is REACH (EC 1907/2006) compliant, meeting the latest environmental and safety directives for industrial components.
