    Worked as expected, good assortment
    Size: 30 PCS
    Used these to replace missing/broken body panel fasteners and they fit as expected. The assortment covered what I needed without having to buy multiple packs. Good quality for the price and handy to keep around if you work on vehicles.

    Must have
    Size: 200 PCS
    If you have machines, you have to have these available. The old ones are reusable, most of the time, but when they aren't, you have these. They are of the same material and quality as OEM. Same size, of course, and the few I have used look factory.

    Replacement for those infamous fastener rivet clips.
    Size: 200 PCS
    Any one who rides or owns a ATV or UTV knows exactly how temperamental this clips can be, they work great when new but as soon as you take them out they never fit right again. This is why I purchased this kit and the clips are exactly the same as Polaris OEM clips. These clips fit into a 8.5mm or 0.3” hole, I’m not sure what other ATV/UTV these will work on but verify your hole size before purchasing. Kit includes 150 fastener rivet clips and 1 remover tool which is made of decent quality and will get the job done until you can purchaser a better removal tool.
