Begin tightening by rotating nuts clockwise, choosing one bolt first, then choosing the bolt 180° opposite second. then one at 90° and then the one 180° from that. Then step over one nut from the first nut tightened (decide for yourself clockwise or counter-clockwise) and continue the same pattern as with the first four.
....
Number the flange clockwise with this sequence: 1, 13, 25, 9, 17, 5, 33, 21, 3, 15, 27, 11, 31, 19, 7, 35, 23, 2, 26, 10, 30, 18, 6, 34, 22, 4, 16, 28, 12, 32, 20, 8, 36 & 24. Now tighten in the criss cross pattern using the numbers. continue to increase torque and go through the pattern until you reach your final torque.

∙ 11y agoThe way to work out any sequence on a even number holed flange is to start of with 1,3,2,4 sequence. You will then add 4 to each number until you reach the total value number of holes. This means on a 28 hole flange your first hole Will be marked 1, followed by 5 next to it, then 9, 13, 17, 21, 25 then put the next number in your sequence, in this case number 3. Again start adding the value 4 until you will lap 28. do not lap but put the next value (2) and then start adding again. you will find that if you counted correctly the last value next to number 1 will be 28. therefore your sequence will be marking consecutively, 1,5,9,13,17,21,25,3,7,11,15,19,23,27,2,6,10,14,18,22,26,4,8,12,16,20,24,28

∙ 11y agoFLANGES WITH 40 BOLTS OR MORE MAY USE A BOLT PATTERN FOR HALF THE NUMBER BOLTS AND TIGHTEN TWO BOLTS AT EACH NUMBER.
FOR EXAMPLE:
40 BOLT FLANGE USE 20 BOLT PATTERN TIGHTENNING 2 SIDE BY SIDE BOLTS FOR EACH NUMBER.
44 bolt flange sequence is 1, 41, 33, 25, 17, 9, 5, 13, 21, 29, 37, 3, 43, 35, 27, 19, 11, 7, 15, 23, 31, 39, 2, 42, 34, 26, 18, 10, 6, 14, 22, 30, 38, 4, 44, 36, 28, 20, 12, 8, 16, 24, 32, 40

How many threads should a bolt engage?
As a general rule, a bolt should engage a distancegreater than or equal to its outer diameter. The number of threads engaged can then be calculated from the number of threads per inch on the bolt. So if you are using a 1/4-20 bolt, meaning it has 1/4" diameter and 20 threads per inch, you should engage the bolt 1/4" into the hole, or 5 threads. (20 threads/inch x 1/4 inches)Why: The shear stress on the threads will be equal to the tensile stress in the shank of the bolt. This means that once you thread the bolt in a distance greater than its diameter, the shank itself will fail before the threads shear off the bolt under tensile load.Sources: Design of Machinery class at Purdue University, page 10 of the following MIT article: http://web.mit.edu/2.75/resources/FUNdaMENTALs%20Book%20pdf/FUNdaMENTALs%20Topic%206.PDF

How you find the pcd of flange?
PCD (Pitch Circle Diameter) is the diameter of a circle that goes through each of the bolt holes. You can find it by measuring distance from centre of one bolt hole to the centre of opposite end bolt hole...
How do you define the nut bolt size?
according to hole dia and flange thickness we divide the dia and length of bolt. normally 1.25 less in dia and 1.25 add in length
How do you make a bolt fit into a larger hole?
I would get a larger bolt. I would get a larger bolt. If I wanted to make a bolt fit into a larger hole, I would use a SMALLER bolt than the hole.

Does toilet have to be removed to install new floor?
Yes that's what the flange sit on and get bolted onto that is why if you remove the toilet/flange you will see a hole in your floor
Why are bolt holes for a flange never placed on the vertical?
I would say because there has to be a standard method of installing flanges that everyone needs to follow. For the simple reason when installing or replacing items such as valves with welded or otherwise fixed flanges, if there was no standard the replacement valve would be 1/8 of a turn or 45 degrees off center if the piping flange bolt holes were on the verticle and the valve flange bolt holes were not. This would be in the case of 4 or 8 bolt flanges.Also in the case of non flanged valves where long bolts pass thru both flanges and squeeze the valve to make the seal a vertically placed bolt hole would interfere with the valve operator or handle preventing the valve from being mounted straight up, down or horizontally.
