Armstrong, a premier brand of Made in the USA industrial hand tools from Apex Tool Group, known for providing innovative, strong and durable solutions, introduced its new Aviation Ratchets.

The new tools help aviation mechanics reach and turn limited-clearance fasteners easily. The 88-tooth ratcheting gear allows technicians to turn fasteners with a swing arc of just 4.1 degrees. Further improving access, the new Aviation Ratchets feature a precision machined, low-profile head with a recessed reversing lever.

“When it comes to aerospace work these ratchets do double duty, offering technicians unprecedented access and strength,” said Jason Wirth, product manager for Armstrong.

Built specifically with aerospace in mind, the ratchets have a pass-through hole for tightening Hi-Lok® and other frangible collar fasteners. The pass-through hole is large enough to accommodate hex keys for fasteners with a nominal pin diameter of up to ¼-inch. The ratchets also feature a retention ring located on the tang, allowing seamless sheet metal fastener engagement and convenient socket pull-off force.
