Master does have a good range of specialty fasteners for cars in their pull our drawers and cheaper than the auto stores "Revolving tree stands"
I find Bunnings in Shepparton to be ok. Staff are usually helpful and as been mentioned previously, they employ some tradies.
We don't have a Masters.
I use Jeays Sandgate [ Mitre 10] , family business, long term staff, tradies at the desk. Not much turn over of staff, some of the faces have been there since 1985. Good service, good advice. Can't help thinking if some of the cheap charlies complaining about the large warehouse outlets had supported their local hardware store, things may be different. As for nuts & bolts, " bolts & industrial supplies " Virginia , get my business. No Chinese crap there. Bob
