Dennis, not sure about the material or thickness of your pad. If it is a concrete pad, you may want to consider removing the old bolt and replacing it with threaded rod using an epoxy anchor system for embedment into the concrete. Powers fasteners has some products we like, including fast...
Not sure about your application but I have used some "re-usable bolts" in a special application for anchoring to concrete. Manufactured by Powers Fastener, they provide data on reuse. The issue I found was accurate tracking of the number of uses and cost of keeping up with the number of uses...
Not sure what type of galvanize environment you are dealing with, but ANSI has standards for galvanize regarding thickness of coating and type of galvanize process. We weld thin coated galivanize channel which I think is a ANSI 423A and "touch-up" the welded spots with a "cold" galvanize. It...
Virgil, don't have empirical data on tension and shear analysis, you can find some of that data on the Powers Fasteners web site. We use an 8 inch wedge bolt for one of our applications. We choose the wedge versus the expansion bolt system for three reasons. 1. If the expansion bolt installer...
It may be more practical to use a non-conductive template. While the torch does cut only what is directly under the arc (flame), it is possible that after the piece you are cutting out is separated that the plasma arc will "ground" through the template to the workpiece. This...
I know your question has been out there for awhile, but if you are still checking, maye this will help. Do you need b&w or color? If you are doing decals, you will probably want a laser jet rather than an ink jet so water will not wash off the ink. If you are doing b&w, the hp LaserJet 5100...
Wobbles, I would try stepping up to a grade 8 bolt with a high pre load and see if this will handle your problem. You may want to try it out on a convenient trouble location to see if this low cost fix will work in your situation and prior to installing solutions with higher labor and expense...
