ISO 2936 (DIN 911 L) Long Hexagon Socket L-Keys Cr-V

The ISO 2936 (DIN 911 L) long series hexagon socket L-key is specifically engineered for fasteners located in deep recesses and narrow spaces where standard tools cannot operate. Featuring an extended long arm, it delivers superior geometric reach alongside significantly higher mechanical leverage for demanding tightening tasks. It is the preferred solution for special machinery assembly, plant engineering, and industrial maintenance.

Manufactured from heat-treated chrome-vanadium steel (58 CrV4 / 1.8161) with a black oxide anti-corrosion finish, it withstands intensive torsional stress over its extended shank length. Calibrated under strict long-series dimensional standards, it ensures an exact, slip-free socket fit that prevents cam-out and drive deformation under high torque.

Benefits:

• Extended Deep Reach: Lengthened shank easily accesses socket screws in deep bores, housings, and recessed housings without interference.
• Amplified Torque Leverage: The extended arm increases leverage, delivering higher tightening torque with noticeably reduced operator fatigue.
• Torsional Elasticity (58 CrV4): Premium Cr-V alloy formulation prevents permanent twisting, shaft warping, and fatigue fractures under high loads.
