Mechanics and DIYers, this double split shaft collar is a seriously handy piece of hardware to have in your toolkit! Made from durable aluminum alloy, it provides reliable clamping force without damaging your shafts. The double split design offers greater axial holding power compared to standard set screws or single split collars, making it suitable for both rigid and flexible shafts. What's really clever is the recessed screw heads - they don't protrude outwards, so you won't snag anything on them, and they protect your shaft surface from marring or damage. Installation is straightforward and doesn't require any special tools - just position it where you need it on your shaft and tighten the screws. The aluminum construction is lightweight yet strong, with oxidation resistance that ensures long-term performance. Available in four sizes: 45mm, 50mm, 55mm, and 60mm, so you can choose the perfect fit for your specific application. These collars are perfect for positioning components on shafts, creating stops, or securing elements in machinery, robotics, automotive applications, or any project involving rotating shafts. The industrial-standard design means it's interchangeable with other quality collars, and the workmanship is precise for a secure fit every time. Whether you're working on professional equipment or hobby projects, having a few of these in different sizes on hand can save you time and frustration. They're one of those simple components that just work reliably, making your life easier when you need to secure something on a shaft quickly and effectively.
