1/2-20 x 2 Fine Hex Cap - Grade 8 Box/4

Overview

The 1/2-20 x 2 Fine Hex Cap Screw – Grade 8 (63025) is designed for high-strength fastening applications requiring fine-thread engagement and wrench-driven installation.

Technical Features

• Grade 8 Classification: Denotes a high-strength fastener rating, making this screw suitable for demanding mechanical and structural connections where lower-grade fasteners may fail under load.
• 1/2-20 Fine Thread: The fine thread pitch (20 threads per inch) provides greater thread engagement per unit length compared to coarse thread, resulting in improved resistance to loosening under vibration.
• 2-Inch Length: Provides adequate grip length for applications requiring deeper material penetration or multi-layer fastening.
• Hexagonal Head Design: The six-sided head is engineered for wrench-driven installation, enabling high torque application and secure, repeatable tightening.
• Yellow Finish: Indicates a zinc yellow-chromate or similar protective coating, providing a visual identifier and a baseline level of corrosion resistance compared to uncoated fasteners.
• Box Quantity of 4: Packaged in a discrete count, reducing waste and allowing precise procurement for low-volume or specialty repair tasks.

Applications

• Mechanical assemblies where fine thread engagement and high clamping force are required.
• Automotive, heavy equipment, and industrial machinery applications that specify Grade 8 hardware.
• Structural connections subject to vibration where fine-thread fasteners reduce the risk of loosening over time.
• Replacement or repair fastening where an exact-specification, hard-to-find screw is needed in small quantities.
