Buttress thread connections are made up to correct "torque" by burying half of the stamped triangle one the Casing pin end. As a rule the torque will vary a few hundred foot pounds either way.
A good habit is to always use this method, but if the client requires a torque figure then and average torque reading over 10 connections can be used as a indicator but this could end up with a previously run connection not sealing due to "run in" deformation and this is highly undesirable.

What is the lowest point of a thread?
The lowest point of a thread typically refers to the deepest part of the thread's profile, which is the root. In the context of screw threads, this is the area between the crests of adjacent threads. It is crucial for determining the thread's strength and load-bearing capacity, as well as for ensuring proper fit and engagement with corresponding threaded components.
How do you find the circumference of a ball?
Put a thread arround the ball and measure the thread's length.
What small cylinder shape holds tape and thread?
A Spool
How do you draw the circle with radius 30cm?
-- Stick a nail into a board. -- Tie a piece of thread around a pencil. -- 30 cm from the pencil, stick the thread to the nail. -- Draw a line on the board with the pencil. Keep the thread tight and go all the way around the nail. -- The line is a circle with radius 30 cm.
What is the relationship between clipping and repainting?
When a window is repainted by the AWT painting thread, it sets the clipping regions to the area of the window that requires repainting
What is the proper makeup torque of 5.5 buttress thread casing?
As always with buttress thread casing, burying half of the triangle (or the 'delta') provides the proper make-up torque.

Can you give an example of a g76 cycle for buttress thread?
A G76 cycle for a buttress thread can be programmed in a CNC lathe as follows: G76 P020060 Q0.1 R0.05 G76 X10 Z-20 P500 Q100 F2 In this example, P020060 specifies the thread pitch and angle, Q0.1 is the retract amount, and R0.05 is the thread depth. The second line defines the final diameter (X10), the final length (Z-20), and the thread parameters such as P500 (depth of cut), Q100 (number of passes), and F2 (feed rate). Adjust these values according to your specific buttress thread requirements.

Will buttress thread interchange with TCPC thread?
Buttress threads and TCPC (Trapezoidal Controlled Pitch) threads are not interchangeable due to differences in their profiles and thread geometry. Buttress threads have a flat flank on one side and a sloped flank on the other, designed to handle axial loads efficiently, while TCPC threads feature a trapezoidal shape optimized for specific applications like lead screws. Using one type in place of the other can lead to improper fit, reduced strength, and potential failure in mechanical applications. Always consult specifications to ensure compatibility.
How do you rethread a ballet shoe?
My dance sewing kit contains an upholstery needle, which is fairly blunt and has a large eye. When a string disappears, I proceed as follows: 1. Find a point in the casing where you can feel the string. 2. Make a small cut in the casing at that point, or a bit further back. 3. Use the blunt end of the needle to pull the string out of the casing through the hole. 4. Thread the needle with the string. 5. Put the needle into the casing and thread through. I do not usually bother to sew up the hole in the casing. It doesn't seem to grow or cause a problem, and of course it might come in handy again. I do like the idea of the spaghetti-strap hook or just pull out the drawstring completely, thread into a bodkin and rethread through the casing. It takes less than 2 minutes
What does the thread guide do on the sewing machine?
The thread guide keeps the thread running in the proper place. If the thread is not threaded correctly, the tension will be off, resulting in jammed or broken threads in the machine.On a sewing machine, the thread guide is a small part that is attached above the needle. It looks like a hook and it hold the thread in place as it is fed through the needle.
What is the the proper thred notation for a 14 millimeter thread with a 1.5 millimeter pitch on a screw that is 40 millimeters long?
The proper thread notation for a 14mm diameter screw with a 1.5mm pitch and 40mm length would be M14x1.5x40.
What is the proper thread notation for a 40 mm screw with 14mm thread 1.5 mm pitch?
The proper thread notation for a 40 mm screw with a 14 mm thread and a 1.5 mm pitch would be M14x1.5. In this notation, "M" indicates a metric thread, "14" represents the nominal diameter of the screw in millimeters, and "1.5" signifies the pitch of the thread in millimeters. This notation is commonly used in engineering and manufacturing to specify the thread details of screws and bolts.
What does the thread take-up do on a sewing machine?
The take up lever is used in threading the sewing machine and to keep the thread tension at the proper level. If the take up lever is threaded improperly, the thread will knot up and jam in the machine.
Why is thread-sealing compound not used on flare connections?
Thread-sealing compound is not used on flare connections because the sealing mechanism of flare fittings relies on the mechanical compression of the flare against the mating surface rather than the thread itself. Adding thread-sealing compound can interfere with the proper seating and create leaks. It is recommended to only use the appropriate flare nut and proper installation techniques to ensure a leak-free connection.
What does thread take up do?
Thread take-up refers to the mechanism in a sewing machine that controls the amount of thread released from the spool to create stitches. It adjusts the tension and length of the thread as the needle moves up and down, ensuring even stitching. Proper thread take-up is crucial for achieving consistent stitch quality and preventing issues like thread tangling or breakage. Adjusting it can help accommodate different fabrics and thread types for optimal sewing performance.
