For years i've been struggling to find oddball engineering supplies (although E Hayes in invercargill often had something downstairs) but lately even run of the mill stuff of some quality is hard to find... today i'm looking for 3/8 unf grade 8+ non serrated flange nuts for a fairly important application.
regarding quality there are lots of inferior hardware finding its way into industry lately - eg assembling a hydraulic ram for an earthmover and noticed the new 1 1/2 unf nut that holds the piston on the spear had its face well crooked to its thread...a total disaster in waiting.
so 2 questions - does anyone have a dependable source of good hardware? and is there a top-level heat treatment company thats good for one-offs and small batches? heat treatments in auckland used to be but recent staff turnover etc ...
