The STANLEY 94-158 9-Piece Extra Long Ball Point Hex Key Set is a professional-grade Allen key collection designed for demanding fastening applications where extended reach and angled access are essential. This comprehensive set includes 9 extra-long ball-end hex keys sized 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10mm, manufactured from premium S2 alloy steel (some sources cite Chrome Vanadium Steel) for exceptional hardness, torque resistance, and long service life.toolbuy+4

Each key features a spherical ball-end tip that allows 25° angled working, enabling faster, easier access to recessed, deeply seated, or awkwardly positioned hexagonal screws and bolts. The extra-long design provides extended leverage and reach compared to standard hex keys, making it ideal for applications in tight spaces, machinery maintenance, automotive repair, and industrial equipment servicing

The keys are manufactured to ANSI B18.3.2M-1979 and GGG-K-275D standards, ensuring precise sizing, reliable engagement, and consistent performance across all applications. A fine satin finish provides corrosion resistance and reduces glare, while the heat-treated construction enhances durability and resistance to wear, stripping, and deformation under heavy loads.

This set is perfect for professional mechanics, engineers, technicians, and serious DIYers working on automotive systems, industrial machinery, bicycles, furniture assembly, HVAC equipment, and general maintenance tasks. The compact, organized storage (typically supplied in a plastic holder or case) keeps all 9 keys sorted and portable for toolbox or jobsite use. Whether you need extended reach for deep fasteners or angled access for tight spaces, the STANLEY 94-158 delivers professional-grade performance, precision, and durability that stands up to daily professional use.
