For all you DIYers and mechanical folks, these SUS301 constant force springs are seriously handy! Made from stainless steel 301, they're built to last and provide consistent force throughout their extension. Each spring has an inner diameter of 0.73 inches, outer diameter of 0.96 inches, and can handle a load of 4.12 pounds. The total length is 29.02 inches, with an extended length of 24.02 inches - the material wideness is 0.63 inches with a thickness of 0.0098 inches. You get five springs in each pack, which is great because let's be honest, springs have a way of disappearing when you need them most! These are perfect for all sorts of applications - retractable cords, tape measures, window counterbalances, or any mechanism where you need smooth, constant force. The SUS301 stainless steel means they're corrosion-resistant and will maintain their spring properties through thousands of cycles. The dimensions are precise and consistent across all five springs, so you can rely on them for your projects. Whether you're repairing existing equipment or building something new from scratch, having a few of these on hand is always smart. Much better quality than what you'd find in cheap imported tools, and having five means you've got spares for future projects too!
