Wera Tools 9-Piece SAE L-Key Hex Set features a re-designed classic L-Key with Hex-Plus technology, ing a larger contact surface in the screw head to prevent rounding out and reduce notching effects. This design significantly lowers the risk of damaging hexagonal socket screw recesses while allowing the keys to withstand 20% more applied torque. The ball tip end on the long arm enables working in tight spaces by allowing the tool to swivel and drive screws at an angle or around corners. Each key is laser engraved and color coded for easy and quick size identification. The BlackLaser surface treatment prevents corrosion and extends the tool's lifespan. The set is conveniently stored in a clip fastener that ensures secure storage, easy removal, and protection against wear. Model Number: 05133180001
