Overview

The NSi Industries HK516 is a 5/16-inch hex key manufactured from high-strength alloy steel, delivering superior toughness and wear resistance for demanding industrial applications. Its plain finish provides a clean, uncoated surface resistant to corrosion in general-purpose use. The short arm design enhances leverage and control, enabling access to tight spaces and hard-to-reach fasteners where standard-length hex keys cannot fit. This hex key is precision-ground to meet tight tolerances, ensuring consistent fit and torque application on common 5/16-inch mechanical fasteners. Ideal for assembly, maintenance, and repair tasks in manufacturing, automotive, aerospace, and machinery sectors, the HK516 supports professional-grade performance without the bulk of longer arms. Alloy steel construction offers a balance of hardness and ductility, reducing the risk of rounding off fastener heads compared to standard steel tools. The 5/16-inch size is a standard specification for many bolts and screws in mechanical systems, making this tool a versatile addition to any technician’s kit. Manufactured in the US by NSi Industries, a trusted name in industrial tooling, the HK516 is built for long service life in workshops, production lines, and field service environments.
