This high-quality set from Allen features 13 hex keys with ball ends. The ball ends allow up to a 25° entry angle in screws, making them perfect for hard-to-reach areas. These keys follow the United States customary (Imperial) system and are great for all SAE parts. Each key is made of black oxide-finished, tempered steel alloy. They come in a noninterference hinged “caddy” for easy access. Precision-formed to exact tolerances, they offer a perfect fit. Included are keys in sizes 0.05', 1/16', 5/64', 3/32', 7/64', 1/8', 9/64', 5/32', 3/16', 7/32', ¼', 5/16', 3/8', plus a hex key caddy.
Using this hex key set is easy. First, pick the right size key for your SAE part. Insert the ball end of the key into the screw. You can use it at an angle up to 25 degrees to reach tight spots. Always apply steady pressure when turning the key to avoid stripping the screw. When you're done, put the keys back in the caddy for easy storage. To keep the keys in good condition, wipe them clean after use. Avoid using them on extremely hard materials that could damage the tempered steel. And if the keys get wet, dry them thoroughly to prevent rust.
