For a tools & hardware listing this is the one we would keep; the black phosphate fasteners & hardware pro just works. At a glance Type: Hex Bolts Material: Black Phosphate Drive: Hex Size: 6 x 40 mm Price: à§³12.36 (offer à§³11.42) The part most missed Set up as a hex bolts-class unit, it does the job without asking you to improvise. In practice Daily duty: handles the regular routine without constant babysitting. Storage: stows neatly, taking no more room than a loaf tin when out of service. First use: no break-in ritual required beyond a quick wipe and a glance at the label. Reasonable to buy, easy to live with, boring in exactly the right way.
