(975) An externally threaded fastener, with a trimmed hex head and a washer face on the bearing side, manufactured in accordance with SAE Standard J429 Grade 5. (Its body tolerances are more exacting than a hex machine bolt.)
Used in a variety of general purpose applications depending on the grade of the material.
(756) An externally threaded fastener, with a trimmed hex head and a washer face on the bearing side, manufactured in accordance with SAE Standard J429 Grade 8. (Its body tolerances are more exacting than a hex machine bolt.)
Used in a variety of general purpose applications depending on the grade of the material.
(993) An externally threaded fastener, with a trimmed hex head and a washer face on the bearing side. (Its body tolerances are more exacting than a hex machine bolt.)
Used in a variety of general purpose applications depending on the grade of the material.
(22) An unslotted hex-washer machine screw, but with a thicker flange and serrations on the bearing surface side.
Used in applications where loosening forces are present, such as vibration. The serrations grip to the bearing surface so that significantly more torque is needed to loosen than to tighten the screw. Eliminates the need for a lock washer or lock nut.
