We aren t manufacturers of those parts and we don t have the testing ability in house so I reached out to a couple of our manufacturers to see what information they could provide to try and help I reached out to my contact at Curt regarding the pin and clip C21500 and he said they haven t ever needed to test the sheer strength of a pin because the hitches and ball mounts

Spring Pin to affix a hub or gear to a shaft is the Coiled Pin s ability to prevent hole damage Another benefit is that the Coiled Pin absorbs wider hole tolerances than any other press fit pin This translates to lower total manufacturing costs of the assembly

2015 6 11 nbsp 0183 32 My question Since even the most expensive dowels are vastly cheaper than the even the cheapest guitars I want the dowels to be strong enough to not shear off while the guitar is hanging SO is there a reference for how much weight a dowel will hold when I
