Description

Five flute star clamping knob with 1 inch raised clamping surface in choice of colors. Knobs measure 2-1/2 inches in diameter and 1 inch height. 3-1/8 overall height with included bolt. Bolt protrudes 1-1/8 inch from clamping surface when installed.

These knobs have a 1 inch raised contact or clamping surface for maximum torque on workpiece. This is good where the workpiece or component you are clamping to is harder, such as metal, and won't be damaged by overtightening on the  clamping surface of the workpiece. Some clamping knobs have a full flat clamping surface to give more holding power to reduce chances of damaging softer clamping surfaces such as wood. Our JTLC-20011 knob has a full flat clamping surface.

Considered male threaded knob because they includes 1/4"-20 x 1-1/2" bolt unless you choose to not include it. Installed the the bolt protrudes about a little over an inch. These knobs are fitted perfectly to these bolts, if you want to supply your own size bolt be aware the hex head does not fit all the bolts we have tried in these knobs. Caliper Measurement of the hex flat to flat is approx. 7/16 inch. Point to point of the hex measures approx. 1/2 inch.

These knobs could be used with 1/4-20 nuts instead of bolts if desired to make it a female threaded knob.
