● Use when pushing up and fixing the ejector plate such as when setting or replacing the ejector pin. ● Because the L dimension is an integral number of 5mm units + 1mm according to the space which is incremented in 5mm steps, the mold can be installed in the molding machine without any need to counterbore the upper side of the ejector plate. ● Because the threaded part (F dimension) is somewhat long, it is possible to easily set the ejector plate being subjected to the spring load.

※ "Strength rank" signifies tensile strength of bolts. (Example) 10.9
〔 Technical Data 〕 • Screw lower hole table D P.1225
Indicates that the yield point or the minimum proof strength is 90% of the tensile strength. Indicates that the minimum tensile strength is 980N/mm 2 {100kgf/mm 2 }.
