4-Pcs Set Screw Shaft Collars - 5/16" Bore, 5/8" OD, Zinc Plated Steel For Rods & Axles

About This Product

Need to stop, space, or secure something on a shaft? These set screw collars are your go-to hardware. This set gives you 4 collars, each with a 5/16 inch bore (fits a 5/16\ shaft), a 5/8 inch outer diameter, and a 5/16 inch width. They're made from zinc-plated steel, so they're strong, corrosion-resistant, and easy to maintain. The set screw (you'll need a hex key) tightens down onto the shaft to lock the collar in place securely—no slipping. You can slide them anywhere along the shaft for adjustable positioning, making them perfect as stops, spacers, bearing surfaces, or to hold gears, pulleys, and sprockets in place. Used in all sorts of stuff: 3D printers, robotics projects, automotive work, machinery, you name it. Installation is a no-brainer: slide it on, tighten the screw. Keep your projects aligned and secure with these versatile little clamps.
