Here are a couple of examples of the hex wrenches that work with these screws:

Inch Hex L-Key

Standard, .050″ Hex, 1-3/4″ Length

Keys are made of alloy steel and have a black-oxide finish. Hex size is measured across parallel flats.

Hex Size: 0.050″ | Length: 1 3/4″ | $0.14 Each | 7122A13

Hex Driver

.050″ Hex, 2-3/8″ L Blade, 4-13/16″ Overall Length

Use hex drivers to tighten or loosen hex socket screws—they’re as easy to use as regular screwdrivers. Blades are steel; handles are plastic.

Hex Size: 0.050″ | Blade Length: 2 3/8″ | Overall Length: 4 13/16″ | $4.85 each | 7400A11

Here is a lock washer for these screws:

18-8 Stainless Steel Split Lock Washer

Number 0 Screw Size, .137″ OD, .015″ min Thick

Compared to regular flat washers, split lock (or spring lock) washers reduce the likelihood that your fastened joint will loosen under shock or vibration. Under compression, spring tension forces the split ends to dig into mating surfaces and hold tight.

Type 316 stainless steel provides better corrosion resistance than 18-8 stainless steel. 18-8 stainless steel offers excellent corrosion resistance. Both materials may be mildly magnetic and have a minimum Rockwell hardness of C35.
