    Galvanic Corrosion Prevention Options

    Hi everyone, I'm currently working on a project where the client wants all 316 fasteners on a polyurethane bend restrictor. However, on the bend restrictor, on the droop line, we've added a clump weight made out of carbon steel (cost reasons) and I am trying to determine how to prevent galvanic...

    Regular Height Nut vs. Reduced Height Nut

    Hi all! I have a product which uses standard 316 nylock nuts. In one scenario, I need to use a reduced height 316 nylock nut for clearance. Is there a rule of thumb or quick calculation I can perform that will tell me what reduction in strength this causes?

    Standard washer deformation under reduced bolt torque

    Thanks for the responses. I ran a quick FEA to visibly see what is going on. As I increase the thickness of the washer, many of these issues change significantly. Bad thing is, can't get a standard off the shelf washer that is thicker but not larger in OD. LittleInch, I will keep that theory...

    Standard washer deformation under reduced bolt torque

    I currently work with polyurethane parts that we must bolt together. Because of the reduced max compressive stress limit on the PU, I perform non-standard bolt torque calculations in order to preserve the integrity of the PU. For my current project, I noticed that when the fasteners are torqued...
