Hilitchi230Pcs Socket Set Screw Assortment in SAE Sizes Internal Hex Drive Cup Point Allen Grub Screws 12.9 Class Black Alloy Steel (10Sizes)

The picture I added is a picture of a 3pt tiller. I had to replace a bearing in this tiller and in order to do that I had to remove the drive sprocket. When I went to remove the sprocket I found it had two set screws that held it on. One set screw was missing completely and the other was loose. Instead of trying to find the set screws to replace these I bought this set and it had the screws I needed. They bolted down nice and tight. Problem solved. I know I'll never use all these screws, but I got them if I need them.

It's a set of assorted sizes. These worked as expected and up to specification. Only needed a few to repair machineries. Useless when not in need but a life saver when am looking to replace a broken fastener of a mission critical equipment.

My antenna uses two set screws and the vibrated out somewhere. I like having different lengths of set screws for different thicknesses of materials. Only thing I found to be lacking is quality of the allen wrenches. Mine stripped out first try on #8 screw.

Sturdy retention hardware for any job.

Not too much to say, here, they seem well made, with clean threads. Worked for making a new depth stop for my bandsaw. The included Allen wrenches were a nice touch.

Just what I asked for, a box of screws.

Received the package, and all of the box dividers had fallen out of their slots because the quality of the box is very poor. All the fasteners were mixed up so I needed to re-sort all of them. Then I needed to glue the dividers in their slots which fit very poorly.In addition, the label that comes with it lists the fasteners by wrench size. No mention of the fact that the fastener size is different. By the way, the sizes are 6-32, 8-32, 10-24, 1/4-20, 5/16-18, and 3/8-16.

The screws appear to be of average quality. They should do the job. Did not receive all 200 pieces, however. The case is made of flimsy plastic and was cracked allowing the screws to come out. They were also mixed together and needed to be removed and separated into the correct size bins. Could of been a better experience.

Nice to have in the shop . Saves going to the bolt house every time I need a set screw .

Haven't had to use it yet.

handy to have when needed

not a lot of unwanted screws in this collection like some that are advertised, price was right and quick delivery
