I feel much better using stover nuts for most things when I installed bolts in the past. I can see a nylock not being sufficient enough for transport Canada anymore and being replaced with the stover nut, I wasn't aware it was code thoughĪ nylock is good for a first use application and can still be reused as long as it wasn't installed with a numatic air tool although the preferred choice is to discard it and use a new one. If you limp this way for a year or two without a giant wreck that sucker will rust in there so solid you can never remove it.Ī person can receive an infraction for leaving your hitch in place while not being connected to a load. Originally being from saskatchewan I know that to make it truly safe put whatever rusty bolt kinda fits, drill a hole through the threads, insert ardox spike or haywire through hole. Some other componant will give out long before the grade 8Ĭase hardened will probably stand up to repeated shear Loads betterĪs far as i can see the only reason to use a Grade 8 bolt would be to locktite a nut on it to stop people from stealing your hitch (Cheaper than a Locking HitchĪnd Curios why if you are making a hitch pin as you did WhY?īolt is 5.50 for a 4.5" so probably 6 for a 6" plus you have to cut, drill and grind it And by a R Pin I would say pretty close and your grade 8 will totally work. In the end a hitch pin however graded or manufactured is the correct tool for the job and therefore a "Proper Pin"ĥ/8 Case Hardened Hitch Pins shear rating 30000 There are those who will say it's fine and there are those that will say its not. The story i told was my own observation of why "I" personally don't think its a good idea to use a grade 8 bolt in this application. ![]() My explanation of a "Proper Pin" was exactly that. What is the tensile strength of a 'proper' pin? Not quite sure what the definition of a 'proper' pin is supposed to be. (not too crazy about how he strikes towards his own hand, but he makes the point). There's still some belief out there that increased tensile strength must mean brittleness. Shear strength is some fraction of tensile strength (maybe 60%), but it doesn't go negative as tensile strength increases. It doesn't just mean hardness, but also tensile strength. ![]() A grade 8 bolt will typically still have strength and some elasticity after a gr5 would have gone past its limit and failed.
