Hey there! If you're tired of struggling to find the right length pins for your projects, these adjustable clevis pins are about to make your life so much easier. Each pin measures 1/2 x 2 inches (that's about 12.5mm x 50mm for you metric folks) and comes with those super handy R-clips that keep everything securely in place. The multiple holes along each pin mean you can adjust the effective length to fit exactly what you need - no more settling for 'close enough'! They're made from carbon steel with a zinc coating that helps them stand up to all sorts of weather and conditions without rusting out on you. Each set comes with 4 clevis pins and 4 matching R-clips (the clips are about 1.6 inches long with a 2.5mm diameter), so you've got plenty to work with. These work great with cotter pins and hitch pins too if you need to mix and match. Perfect for automotive work, farm equipment, trailers, or any DIY project where you need a reliable, adjustable connection point. The zinc coating isn't just for looks - it really does help these last longer when they're exposed to moisture or outdoor conditions. Seriously, if you've ever wasted time searching for that one perfect pin size, these adjustable ones will save you so much frustration. They feel solid in your hand, the finish is smooth, and they just work like they're supposed to. Definitely one of those 'why didn't I get these sooner' kind of tools!
