S-91864A073 7/16"-20 x 3/4" ASTM A574 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh environments, minimizing maintenance needs.
• Precise Class 3A thread fit guarantees tight, secure connections with minimal backlash, enhancing assembly accuracy and vibration resistance.
• Fully threaded design allows for uniform load distribution and adjustable positioning, providing flexibility in various mounting scenarios.
• High hardness (Rockwell C37) offers excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
• Fine thread spacing (UNF) delivers improved clamping force and better sealing in fine-adjustment applications compared to coarse threads.
• Hex socket drive (3/8") enables easy installation with standard tools, reducing assembly time and improving workplace efficiency.

Professional Applications & Engineering Value

This 7/16"-20 UNF socket head cap screw is engineered to address critical challenges in demanding industrial settings, such as machinery assembly, automotive systems, and precision equipment.
