4 mm Short Arm Ball End Hex L-Key

• Short Arm for Access – The L-key's short arm enables you to stay close to the fastener so that you can work in tighter spaces and with greater control • High Leverage – Our L-keys are longer in overall length compared to competitors, providing increased leverage where it matters • Tight Fit with Fasteners – We precisely manufacture our hex key geometry on the large end of the applicable range, resulting in less slop in fasteners • 20-Degree Ball End – Our keys implement a steep ball end angle, which increases your ability to access fasteners while still maintaining sufficient strength • Markings and Finish – Each key is marked with a high-visibility size indicator that can't wear off and finished with a manganese phosphate coating that's highly resistant to corrosion
Tekton's short arm L-keys have one ball-end arm that's the same length as our normal keys, and one flat-end short arm that's markedly shorter than our regular keys. This shorter arm allows the key to fit into tighter spaces where a regular-sized key cannot. The short arm L-keys are made from 8660 nickel chromium molybdenum steel that's heat-treated to 54-58 HRC and coated with a highly corrosion-resistant manganese phosphate finish. With the exception of the smallest sizes that are too small to mark, each key has a high-visibility laser marking and a stamped marking that won't rub off.
