While TSO Products generally recommends the M8 SpeedKnobs as the ultimate solution to secure 20 millimetre bench dogs, these M8 Star Grip Knobs are an economical alternative. Like the SpeedKnobs, they share the same M8x1.25 thread common in all DoubleGroove Dogs as well as most other bench dogs on the market. With a star shape and soft-touch plastic, they are easy to use even with gloves on. Note: Because the clamping surface area of these knobs is only 14mm, a pair of laser-cut Delrin washers are included that apply clamping pressure outwards to work on the 20 millimetre holes standard in many worktops.
