  • The STONEC® Professional 10-Piece Extra Long Hex Key Set is designed for high-torque fastening and accessing deeply recessed socket screws in automotive, machinery, and industrial equipment. Crafted from premium Chrome-Vanadium (Cr-V) alloy steel with precise, chamfered tips, these L-shaped keys seat cleanly into hex sockets to reduce wear and prevent fastener stripping. The set covers 10 key metric sizes: 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 4.0 mm, 5.0 mm, 5.5 mm, 6.0 mm, 8.0 mm, and 10.0 mm. The extra-long arm design (ranging up to 13.5 inches) provides superior leverage for breaking loose stubborn fasteners while extending reach into tight engine bays and mechanical assemblies. Organized in a durable hinged storage caddy with clearly marked size slots for easy selection and transportation. Sealed in a protective retail blister pack.

Key Features & Standards

  • Comprehensive 10-Piece Metric Range: Includes 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 5.5, 6.0, 8.0, and 10.0 mm keys to fit all standard socket head cap screws.

  • Extra-Long Arm Design: Extended key length (up to 13-1/2") maximizes rotational leverage and reaches deep, obstructed socket bolts effortlessly.

  • Chrome-Vanadium Alloy Steel: Drop-forged Cr-V steel provides high torsional strength and torque resistance to resist twisting or deformation.

  • Chamfered Precision Tips: Beveled hexagonal edges slide smoothly into fastener heads to ensure a snug fit and prevent rounding of bolt sockets.

  • Organized Storage Caddy: Custom yellow hinged holder keeps all 10 keys indexed and secured for convenient shop or jobsite portability.

⚠️ Safety Warning: Always select the exact matching hex key size for the socket bolt to prevent stripping. Do not use pipe extensions ("cheater bars") on keys to gain extra leverage, as this can snap the tool. Wear ANSI-approved eye protection during high-torque mechanical operations.
