S-92695A689 5/8"-11 x 1 3/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with a 90° cone point that digs into surfaces for secure, vibration-resistant fastening in demanding applications.
• Superior corrosion resistance thanks to the black-oxide coating on the alloy steel, extending the component's service life in various industrial environments.
• High-strength durability from Rockwell C45 hardness, ensuring the set screw maintains its form and function under high stress and load.
• Precise and reliable fit with a Class 3A thread fit, providing tighter tolerances for improved assembly accuracy and reduced risk of loosening.
• Easy installation and removal with a standard 5/16" hex drive, allowing for efficient maintenance and adjustments with common tools.
• Broad industrial compatibility due to UNC coarse threading, enabling quick assembly and reliable performance in a wide range of machinery and equipment.
• Compliance with major standards including ASME B18.3 and ASTM F912, ensuring quality, safety, and interoperability in professional settings.

Professional Applications & Engineering Value

This 5/8"-11 UNC set screw is engineered to solve critical challenges in industrial assembly, where vibration resistance and permanent positioning are paramount. The black-oxide alloy steel construction provides a robust barrier against rust and wear, making it ideal for automotive, aerospace, and heavy machinery applications exposed to harsh conditions. The 90° cone point design concentrates force to create a deep indentation in the shaft or component, preventing slippage and ensuring a secure lock. Combined with a Class 3A thread fit and coarse thread spacing, it offers quick installation and reliable performance in high-stress environments, reducing maintenance downtime and enhancing operational safety for engineers and OEMs.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 3A thread fit for superior accuracy and a UNC coarse thread with 5/8"-11 size. It meets ASME B18.3 and ASTM F912 specifications for quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various industrial and international markets.
