Ever wondered why hexagonal (Allen) keys are so common in mechanical design?
Their shape allows for:
– torque transfer from multiple sides,
– minimal slippage,
– and easy access in tight spaces.
They’re cheap to produce, durable, and safer for assembly tools—one of the most efficient fastener systems in mechanical design.
