A Long Arm Hex Key is a six-sided shaped bar bent at a 90° angle on one end. Long Arm Hex Keys are obviously longer than short arm hex keys and they are designed to be inserted into a like-sized hollow recess of a socket cap screw to manually tighten or loosen the fastener.

Long arm hex keys are made from hardened alloy steel and they are stocked in 6150 Crv and 8650 alloy in both imperial and metric sizes.
