How to Select the Right Shaft Flex for a Golf Club. Selecting the right flex for your golf club shafts is key to getting the most out of your clubs. Shafts come in five flex categories: extra stiff (X), stiff (S), regular (R), senior (A) and ladies (L).
Aug 02, 2019 · The torque is in the direction of the angular velocity which would be produced by it, so, the change in angular velocity is in the direction of the torque. Use your right hand and curl the fingers of your hand in the direction of rotation caused by the force and your thumb will point in the direction of the torque vector.
First thread has the shortest load path (stiffest) 2. The pitch of the bolt threads and nut threads change as they are loaded What can be done to distribute the load better 1. Use a softer nut material 2. Use a bolt and nut that have different pitch values to begin with 3.

The ASTM A307 is an ASTM International standard for carbon steel bolts and studs ranging from 1/4 inches through 4 inches in diameter which is set by the standards organization ASTM International. Given here is the bolt torque chart for the ASTM A307 bolts.
But bolt lubrication is also crucially important for assembling flanges properly. Using proper bolt lubrication practices will allow assemblers to achieve the ideal torque with a low degree of bolt scatter (which we define as differences among torque levels on different bolts holding together the same flange). Proper bolt lubrication means:
Bolt tightening sequence or torque sequence is defined in the torque tightening procedure. Most company has their Flange bolt torque tightening procedure that used during construction and operation of the plant. Flange joints are torque tight with the help of a torque wrench (Manual or hydronic wrench).
