  • A Good Value For Metric Hardware
Color: Black-M6 Bolt
This an excellent assortment of m6, the most common metric thread out there, at a great price. I bought this for replacement bolts for a table & chair set that my grand kids are rough on, as just about every time that I would come to visit, there would be missing bolts (that had fallen out and disappeared).
