This is massive vise hardware, with 2 1/2" diameter threads CNC-milled from solid sugar maple, a wood that combines hardness with a close grain structure to hold crisp detail and resist chipping and wear. The fit and finish are exceptional; the screw turns smoothly and evenly in the nut, the handle ends are securely attached and padded with rubber O-rings, and the wood is sanded to 220x, ready for finish.
