S-92695A843 3/4"-10 x 7/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications
• Enhanced corrosion resistance from the black-oxide finish on alloy steel, extending service life in industrial environments
• High-strength durability with Rockwell C45 hardness to withstand heavy loads and prevent deformation
• Secure component positioning thanks to the 90° cone point that bites into surfaces for reliable, non-slip contact
• Easy installation and removal with a 3/8" hex drive, allowing for high-torque application using standard tools
• Broad compatibility with UNC coarse threads (3/4"-10) for quick assembly and reliable performance in right-hand threaded systems
• Regulatory peace of mind by meeting ASME B18.3, ASTM F912, RoHS 3, and REACH standards for safe, compliant use

Professional Applications & Engineering Value

This 3/4"-10 UNC set screw is engineered to address critical challenges in industrial assembly, such as shaft-hub connections and machinery alignment, where vibration resistance and permanent positioning are paramount. The black-oxide alloy steel construction provides a protective layer against rust and wear, while the Rockwell C45 hardness ensures the fastener maintains its integrity under repetitive stress. The 90° cone point design concentrates force for deep embedding into materials, preventing slippage in high-torque environments. With a coarse thread spacing and Class 3A thread fit, it offers quick installation and reliable grip, making it ideal for use in automotive, heavy machinery, and precision equipment where hex drive accessibility is essential for maintenance and adjustments.

Specification Summary & Compliance

This set screw adheres to Class 3A thread fit tolerances for precise engagement, with UNC coarse threads (3/4"-10) and a right-hand direction. It is manufactured in compliance with ASME B18.3 and ASTM F912 specifications, ensuring dimensional accuracy and performance reliability. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for industrial use.
