ISO 2936 (DIN 911) 9-Piece Long Ball End Hex Key Set Cr-V

The 9-piece ISO 2936 (DIN 911) long ball end hexagon socket L-key set in blued finish is engineered for servicing recessed socket screws and threaded assemblies situated behind structural obstacles. Stored in an ergonomic, impact-resistant plastic holder, this compact 9-piece selection provides portable, organized access to long-series keys, enabling rapid tool extraction while preventing job-site misplacement.

Manufactured from heat-treated chrome-vanadium steel (58 CrV4 / 1.8161), each key integrates an extended shank with a 25° ball profile tip on the long arm, allowing off-axis engagement where direct perpendicular alignment is blocked. The durable chemical blued surface delivers baseline anti-corrosion protection and an anti-glare finish, while the standard short arm ensures rigid, high-torque final tightening.

Benefits:

• 9-Piece Long-Reach Assortment: Features 9 essential metric dimensions with lengthened shanks to reach deeply inset fasteners and threaded rods.
• 25° Off-Axis Swivel Operation: Precision ball-end tip permits fast rotational drive at angles up to 25°, bypassing physical obstructions effortlessly.
• Functional Compact Holder: Sturdy open-faced organizer securely locks keys by size, allowing one-handed selection and clean integration into tool belts or service drawers.
