HARFINGTON 4pcs 15mm Bore Shaft Collar Set - Aluminum Alloy Set Screw Clamp Collars, 35mm OD, 12mm Width

Need a simple way to position components on a shaft? These aluminum shaft collars are super handy. Each collar has a 15mm bore (inner diameter), 35mm outer diameter, and is 12mm wide. They're made from 6061 aluminum alloy with a sleek anodized finish that resists corrosion and looks pro.

The set screw design lets you tighten them securely onto shafts—works great on both hard and soft shaft materials. Use them as stops, spacers, or to hold gears, pulleys, or wheels in place on axles. Comes as a 4-pack, so you have extras for different projects. Perfect for DIY machinery, CNC builds, go-karts, wheelbarrows, or any workshop application where you need precise axial positioning. Just slide on, tighten the set screw with an Allen key, and you're set. No welding, no fuss.
