5/8-11 x 1 Hex Cap Gr5 Zn

Overview

The 5/8-11 x 1 Hex Cap Screw (53384) is designed for general fastening applications requiring a wrench-driven hexagonal head fastener in Grade 5 zinc-plated construction.

Technical Features

• Hexagonal head design — provides full wrench engagement on all six contact points, enabling high torque application without slippage.
• 5/8-11 thread specification — designates a 5/8-inch nominal diameter with 11 threads per inch (UNC coarse thread), ensuring broad compatibility with standard UNC nuts and tapped holes.
• Grade 5 construction — meets SAE Grade 5 strength requirements, offering a higher tensile and proof load rating than Grade 2 fasteners for medium-duty structural use.
• Zinc plating finish — provides a corrosion-resistant barrier, suitable for general indoor and light outdoor applications where moisture exposure is a factor.
• 1-inch grip length — consistent clamping length allows predictable joint compression across standard material stack-ups.
• Sold in 15-piece quantity — packaged in a job-lot count suitable for small projects, repairs, or replenishment of hardware stock.

Applications

• General structural assembly where SAE Grade 5 tensile strength is specified.
• Mechanical and equipment fabrication requiring coarse-thread UNC 5/8-11 fasteners.
• Maintenance and repair work involving wrench-driven hex cap fasteners.
• Light to medium-duty assemblies where zinc-plated corrosion resistance is adequate.
