Bondhus 12136 Long Hex Key L-Wrench Set
The Bondhus 12136 (HLX12) is a 12-piece standard hex key L-wrench set designed for precise fitment and reliable torque transfer. The tools feature standard chamfer-milled ends that eliminate cut-off burr issues often found in alternative hex keys, preventing interference with socket engagement and exceeding standard screw-to-key clearance requirements.
Each wrench in the set is finished with Bondhus' proprietary ProGuard™ coating, providing high resistance to rust and corrosion. The precision-machined sharp corners ensure maximum torque transfer to the screw, minimizing the risk of stripping the fastener.
