Advantages:
◊ These clamp-on rigid couplers have much more clamping strength than the set-screw type couplers.
◊ A flat on the shaft is not needed.
◊ These couplers will not damage the shaft.
◊ Made from durable Delrin.
◊ Uses 4x 4-40 stainless steel screws with brass inserts
◊ Tighten the screws about 1 turn past snug. Do not over tighten, a little torque will clamp these on really tight. For best results, re-tighten after a couple hours of use.
