03490070 Stahlwille 440a 1-7/8'' SAE 12-Point Flare Nut Crowfoot Wrench, 1/2'' Square Drive Description

The 03490070 Stahlwille 440a 1-7/8'' SAE 12-Point Flare Nut Crowfoot Wrench, 1/2'' Square Drive is designed for professional service work where a full-size wrench cannot reach the fastener directly. Its 1-7/8'' SAE working size and 1/2'' square drive make it suitable for use with compatible hand-drive tooling in automotive, industrial, machinery, aviation, and general maintenance applications.

Its open crowfoot shape allows the head to approach a fitting from the side while surrounding most of the fastener for more secure engagement than a conventional open-end profile. This makes it especially useful around lines, tubing, and other components that prevent access from directly above.

The 12-Point AS-Drive profile is designed to transmit force through the fastener flanks rather than concentrating pressure at the corners, helping reduce the risk of damage and supporting secure power transfer during tightening and loosening.

The 03490070 Stahlwille 440a 1-7/8'' SAE 12-Point Flare Nut Crowfoot Wrench, 1/2'' Square Drive uses Stahlwille's 440a flare nut crowfoot format to combine compact access with a secure 12-point working profile. The 440a series is manufactured from Chrome Alloy Steel and chrome-plated for durability, corrosion resistance, and wear resistance in professional workshop and maintenance environments.
