摘要：A screw comprising a first member having a plurality of alternating first threadridges and first thread grooves, a ridge width of the first thread ridges being larger thana groove width of the first thread grooves at a measurement diameter of the firstmember. The measurement diameter is determined by calculating a pitch diameter of a

hypothetical member having a plurality of hypothetical thread grooves and hypotheticalthread ridges, with the hypothetical thread grooves being identical to the first threadgrooves, and with the hypothetical thread ridges and the hypothetical thread grooveshaving identical, but opposite, profiles, and with the measurement diameter beingidentical to the pitch diameter of the hypothetical member.
