Frequently Asked Questions

AI
SAE (Society of Automotive Engineers) keys are measured in inches, while Metric keys are measured in millimeters. They are not interchangeable; using the wrong standard can easily strip the head of a fastener.
Folding sets are more compact and better for EDC or bike kits. L-shaped keys offer more leverage and allow you to reach deeper recessed bolts more effectively.
A ball end allows you to insert the key at an angle (usually up to 25 degrees) rather than perfectly straight, which is helpful in tight spaces where direct access is blocked.
