These original Britool Hallmark AF flare nut spanners, made in England, were crafted from high-quality alloy steel for superior durability. With a highly polished, bright nickel and chrome plating, they offer both strength and corrosion resistance. Designed specifically for use on brake or hydraulic pipes, the unique gap in the wrench head allows it to fit securely over the pipe, providing a firm grip on the nut and minimizing the risk of slippage. The heads are set at a 15-degree angle, and each end features a different size for versatility.
Manufactured in the Cannock UK plant before its closure, these spanners are a rare find, offering precision and reliability for any mechanic or enthusiast.
Only now available in limited AF sizes. Please note that the picture may be of a different size but you will receive the size as per your order.
