Claim Text:
1. A locking fastener, comprising: a nut comprising inner threads engageable with external threads on a shaft, a plurality of wrench bearing surfaces engageable with a tool to rotate said nut, and a first torque bearing surface; a retaining ring comprising a rotational retaining member engageable with said shaft thereby preventing relative rotation between said retaining ring and said shaft, a second torque bearing surface engaged with said first torque bearing surface thereby translating longitudinal force from said nut to said retaining ring, a pressure surface adapted to apply said longitudinal force to an apparatus, and a plurality of ratchet teeth extending around said retaining ring; a pawl comprising a ratchet tooth engaged with said ratchet teeth of said retaining ring; and a spring disposed between one of said wrench bearing surfaces of said nut and said pawl, said spring comprising a first arm extending radially outward as said first arm extends downward along said wrench bearing surface, said first arm being biased away from said wrench bearing surface and being compressible toward said wrench bearing surface by said tool, a portion of said first arm biasing said pawl outward against said retaining ring and compression of said first arm by said tool thereby releasing engagement between said ratchet tooth of said pawl from said ratchet teeth of said retaining ring.
