9/16-12 x 1-1/2 Coarse Hex Cap - Grade 5 Box/25

Overview

The 9/16-12 x 1-1/2 Coarse Hex Cap Screw (00359) is designed for general fastening applications requiring a wrench-driven hexagonal head fastener in coarse thread configurations.

Technical Features

• Grade 5 strength rating: Meets SAE Grade 5 specifications, providing a higher tensile strength than Grade 2 fasteners and making it suitable for medium-to-high-stress mechanical assemblies.
• 9/16-12 coarse thread (UNC): Coarse thread pitch engages faster during installation and offers greater resistance to cross-threading compared to fine thread variants, improving efficiency in field and production environments.
• Hexagonal head design: Engineered to be driven by a standard wrench or socket, allowing high torque application and secure tightening without tool slippage.
• 1-1/2 in. body length: Provides defined grip length for consistent clamping force across matched material thicknesses.
• Sold in a box of 25: Packaged in a job-ready quantity suitable for both single-project use and small-batch production work.

Applications

• Structural and mechanical assemblies requiring medium-to-high clamping loads.
• Automotive, agricultural, and industrial equipment maintenance where SAE Grade 5 hardware is specified.
• General construction and fabrication applications utilizing 9/16 in. clearance holes.
• Any application where a wrench-driven, coarse-thread fastener is required per engineering or maintenance specifications.
