Bolt Shank Length - Structural engineering general discussion
2012年2月15日 · Lets say you have a 3/4" dia 2" long bolt in a slip critical connection. You now have a shank length of 5/8". If the connected parts you are connecting are less than 5/8" you can no longer torque the bolt properly because the nut is hitting the shank. Therefore your connection is no longer SC. At least that is how I look at it.
Typical shank tension in a tightened bolt - Eng-Tips
2012年1月11日 · where ks is a factor based on the slotted hole direction, mu is the friction coeff between the plates and P0 is a minimum shank tension (preload) in the bolt. I have no sense for the preload that could be expected by a typical steel fabricator, tensioning to the average man level required with a podger spanner...
Positional tolerance of helical threaded inserts 2 - Eng-Tips
2014年12月17日 · The use of a threaded insert usually guarantees that the shear plane between the two mating parts will pass through the threading of the bolt, not its shank. Meaning the bolt's minor diameter, not its full diameter is the shear load path. Shear-critical joints are not what these fasteners are intended for.
Bending moment on shank of bolt - Welding, Bonding & Fastener ...
2003年9月19日 · Thanks a lot for your reply. As I understand, bending of the shank may not be negligible if the bolt is of reasonable length. As an example, consider the case when the two end plates are 0.5" thick each, with a shim of 0.2" in between. If the bolt is subjected to a shear, what would be the moment arm?
All around symbol callout - Drafting Standards, GD&T & Tolerance ...
2009年8月11日 · I believe that Y14.5 adopted the all-around symbol for profile controls from the welding standard. Those are the only two prescribed uses that I've seen for it. Outside of those two contexts, the symbol is not documented as for its …

2004年5月7日 · They said the screw is #8, and coarse meaning as in fine or coarse threads. Diameter of #8 screw is 5/32 inch at shank and 7/64 inch at root , root governs. 7/64 inch = 0.1094 about 12 gauge which is 0.1046 and that puts …
permissible angular deviation 1 - Eng-Tips
2007年6月2日 · Dear experts, While determining permissible angular deviation, we have to consider length of shorter side of angle. Can anybody kindly explain the " the shorter side of angle" with an example or sketch.
Bolt Threads in a Shear Plane 1 - Eng-Tips
2010年5月8日 · GM has used recessed thread holes for the motor starters for years. The bolt has part of the shank knurled to get it to fit tighter in the starter hole and the non-threaded part of the hole in the block. That allows the bolts to locate the starter and keep it straight on the block. So, it is possible to do it that way.
"TRUE" Meaning - Drafting Standards, GD&T
2008年2月1日 · I feel pretty comfortable about leaving things as they are with regards to "true" holes. It is not a great leap of logic to see how it can apply. What does bother me though, is that the customer actually had engineers asking the meaning. But, then again, seeing how they use GD&T, it isn't all that suprising after all ;-)
Question about using the term 'THRU' on a drawing, when ... - Eng …
2010年8月31日 · Here is another look at the problem: When you specify something like “thru one wall” or “to the cross-hole” you assume that one hole is actually made before the other, so essentially you are suggesting a process, which technically is a big no-no.
