Many places have minimum amounts of bolts, nuts, spacers, etc when you order from them. This place does not. I don't need a dozen 6 mm t-headed bolts. I need 2.
I've used them many times for 2 bolts, 4 washers, couple different sized bolts, yada, yada. Prices seem good, and shipping is very fast.
Just something to tag an place in your favorite bin. Check 'em out.
