螺絲槽深規(guī)用于PH型十字槽螺絲，Z形米字槽螺絲的Q值深度測(cè)量，日本JIS，JCIS，ISO及ISO10664，DIN，ANSI/ASME及推廣國(guó)標(biāo)944.1-85中相關(guān)標(biāo)準(zhǔn)的測(cè)量。在現(xiàn)在的螺絲緊固件生產(chǎn)中，穴深(Q值）的測(cè)量越來(lái)越重要，也是產(chǎn)品質(zhì)量保證的重要前提。螺絲槽深規(guī)的使用也越來(lái)越廣泛，蘇州恒準(zhǔn)儀器代理日本NHK（NISSEIKO)日発精密工業(yè)株式會(huì)社的十字與米字螺絲槽深規(guī)和插規(guī)產(chǎn)品，美國(guó)UNIVERSAL環(huán)球螺絲槽深規(guī)，歡迎來(lái)電咨詢。
