I thought it meant the number of holes and number of decimal places.I'm studying for a quiz I'm having next week and while reading my notes I came across this:(The 0 is supposed to be a diameter symbol and there is supposed to be depth symbol after the 60 degrees. * is supposed to be degree symbol)V 0 3/8 X 60* (followed by depth symbol) 1.00So would it mean: countersink has diameter of 3/8 and the hole is 1 inch welded at a 60 degree angle?
Reply:Your going to have to post a pic of the drawing in questionVantage 500's LN-25's, VI-400's, cobramatics, Miller migs, synch 350 LX, Powcon inverters, XMT's, 250 Ton Acurrpress 12' brake, 1/4" 10' Atlantic shear,Koikie plasma table W/ esab plasmas. marvel & hyd-mech saws, pirrana & metal muncher punches.
Reply:XX° F is correct for degrees F with the XX being the variable. Note the small circle indicating degrees as in a temperature. The same symbol is use for degrees such as 45° 20 minutes. This would indicate an angle.       Ø would be the symbol for diameter.  The X in a welding callout could mean the electrode used is up to the fabricator, such as E70XX would say E=electrode, 70 means 70 KSI and XX means it could be 14, 18, 24, which indicate position, and flux, etc. Example: E7014, E7018, E7024.
Reply:hole diameter is 3/8" and countersunk angle is 60° ?Then you still need a depth to which you need to countersink.

Reply:"2X" I would take to mean 2 places, judging by the cross section on the paperTOOLS AND TOYSSMAW Mid States Inc.

Reply:X on all the blueprints I have seen shows weld._________    XXXX
Reply:Take it to represent the word "by", as in 3/8" inch diameter by 60 degree angle to a depth of 1.00".
