Climax Step Down Adapter - 3/4" To 1/2" Bore Reducer With Set Screw

Mechanics and machinists, this little step-down adapter is one of those simple solutions that saves so much headache! It reduces shaft size from 3/4 inch bore down to 1/2 inch OD, perfect when you need to connect different sized components without major disassembly. The black oxide plating provides decent corrosion resistance while the mild steel construction handles serious torque transmission. The design fully engages the shaft without damaging it - no more marred surfaces or compromised integrity. At 1 3/4 inches long, it's compact enough for tight spaces but sturdy enough for heavy-duty applications. The 1/4-28 x 5/8 set screw keeps everything locked in place securely. Honestly, if you've ever been in a situation where you needed to adapt shaft sizes quickly, this adapter is pure gold. It's one of those workshop essentials that might sit in your toolbox for months, but when you need it, you'll be so glad you have it. Simple, effective, and built to last - exactly what you want from industrial components!
