I somehow managed to lose the setscrew that holds the interior latching knob onto my front door's Abloy deadbolt, circa 1990.
As this is entirely hidden inside the knob, cosmetics are a non-issue. I'm sure this is a commodity item at any hardware store. Can any of you smiths tell me what size Allen wrench fits the Abloy set screw? If I go in and ask for, say, a 2 mm. quarter inch setscrew, chances are I'll have the right item unless Abloy chose some non-standard thread pattern.
