Use a dog to secure thinner material for a template or jig and the base of the dog hits the knob before the face can seat. This recessed M8 knob solves that. A hollow pocket in the base lets the 20mm dog slide up into the knob so the clamping face still lands flat against the underside of the bench.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eWhy it exists\u003c\/strong\u003e\u003cbr\u003eBench dogs are used to locate and hold templates, fences, and tools on 20mm-hole worktops (Festool-style MFT, custom 20×96 grids, and similar). Knobs lock those dogs from below. That only works when the dog does not protrude. This knob keeps the same M8 thread and the same underside clamp — and still works when the dog is proud of the hole.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"auto\"\u003e\n\u003cli\u003eHollow recessed base — the 20mm dog travels into the knob instead of stopping against it\u003c\/li\u003e\n\u003cli\u003eFull face contact on the underside of the workbench for a solid lock\u003c\/li\u003e\n\u003cli\u003eM8 × 1.25 thread to fit the majority of threaded 20mm dogs (TSO, Precision Dogs, Tool Theory, and similar)\u003c\/li\u003e\n\u003cli\u003eUse longer dogs, or through-dogs without swapping hardware\u003c\/li\u003e\n\u003cli\u003eIdeal for securing templates, jigs, and fixtures that made with thinner material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eHow to use\u003c\/strong\u003e\u003c\/p\u003e\n\u003col dir=\"auto\"\u003e\n\u003cli\u003eInsert the 20mm dog from the top (or drop it through for a through-dog setup).\u003c\/li\u003e\n\u003cli\u003eThread this knob onto the M8 hole from below.\u003c\/li\u003e\n\u003cli\u003eIf the dog protrudes, it slides into the hollow pocket.\u003c\/li\u003e\n\u003cli\u003eTighten until the knob face is tight to the underside of the bench.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e Made for 20mm bench dog holes and M8 × 1.25 threaded dogs.
