Armstrong, a brand of Made in the USA industrial hand tools from Apex Tool Group, has introduced its new Aviation Ratchets.
The 88-tooth ratcheting gear allows technicians to turn fasteners with a swing arc of just 4.1°. The new Aviation Ratchets also feature a precision machined, low-profile head with a recessed reversing lever.
New Armstrong Aviation Ratchets are available in both nine-position locking flex-head and static models.
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 1/4-inch. The ratchets also feature a retention ring located on the tang, allowing seamless sheet metal fastener engagement and convenient socket pull-off force.
