  • Nice selection of necessaries
Size: 3/8" 1/4" 5/16"(240pcs SILVER)
Once upon a time, I had a vast collection of nuts, bolts, washers and all kinds of neat stuff. But, I felt that I wouldn't ever need them, so I gave everything away. Then I needed a couple of bolts to make a repair to a pull-down staircase. I no longer had what I needed, so I went to the local hardware store, and wrecked my car along the way. Needless to say, I won't make THAT mistake again. I bought this set, and a couple of others to replace what I gave away. These look really good, and, I may never need them, but, if I do, I will have what I need, and won't have to take another chance to wreck my car again. ... show more

  • Decent kit.
Size: 3/8" 1/4" 5/16"(240pcs SILVER)
Nice selection of hardware, but I find it strange there's not a nut for every bolt. I guess you're gonna be on your own for sourcing extra pieces when you need them. Good corrosion resistance, about what you'd expect for 304 stainless steel.

  • Safety pins
Size: 3/8" 1/4" 5/16"(240pcs SILVER)
Was looking for a large safety pin but not one 3” long and here it is along with normal sizes. This x-large pin is under 3” and is perfect. Als, a handy case so all sizes are in one convenient place. Love it.
