This round knob with a scalloped edge for a comfortable grip is one of our smaller knobs with a diameter of 28 mm. It can be combined with an M4, M5 or M6 hex screw or nut at your discretion. The knob is supplied with a cap which fully closes the knob to leave a clean finished appearance.
CO280 has a shouldered profile to lift the head clear of the surface making this style of knob an ideal frequent use manual fastener.
Use for clamping and locking applications where frequent use is required.
