①,Material
a、Faricated from alloy steel and shall conform in all respects to ASTM F912
b、Faricated from corrosion-resistant steel and shall conform in all respects to ASTM F880
②,When the length L of the screw is less than or equal to L0 in the table, it is a short screw; if L is greater than L0, it is a long screw.
③,The key engagement dimensions t shall apply only to nominal screw lengths L equal to or longer than the lengths L0 listed in this Table. For hexagon socket key engagement dimensions in screws of shorter nominal lengths than L0 of this Table, please refer to the standard original.
④,The use of short-length set screws listed in this Table can result in failure of the socket, key, or mating threads during tightening because key engagement and thread length are less than optimum. Therefore, it is strongly recommended that screws of

lengths equal to or greater than the lengths specified in columns L0 of the table be used wherever possible.
