About this item

  • 【Top Quality 12.9 Grade Alloy Steel】 Unlike the common grade 10.9 alloy steel materials on the market, IEAWISL's M3 screws assortment is made of upgraded grade 12.9 alloy steel, which has higher hardness and is not easy to deform. The surface of the screws is black oxidized for oxidation, corrosion resistance and durability, allowing for long term use in high temperature, low temperature or humid environments.
  • 【One Set For Your Needs】IEAWISL has combined the 8 most commonly used M3 screw lengths and sizes on the market, namely M3x6mm-50pcs, M3x8mm-30pcs, M3x10mm-25pcs, M3x12mm-20pcs, M3x16mm-15pcs, M3x20mm-10pcs, M3x25mm-10pcs, M3x30mm-10pcs. Matching 1:1 with corresponding nuts, washers, lock washers and wrenches to combine into a perfect set of screws set, which promptly solves your anxiety of not being able to find the parts, and at the same time improves your installation efficiency and saves time.
  • 【1:1 Matching Spring Washers】As we all know, nuts and flat washers can increase the contact area and reduce pressure to protect screws and parts. Within the IEAWISL screw and nut kit, we add extra 170Pcs spring washers to prevent the bolts from loosening. So you don't need to buy extra spring washers, saving you more time and money.
  • 【Exquisite Storage Box】In order to solve the problem of damage or size confusion after you receive the m3 machine screw assortment kit, we have upgraded and thickened the packaging box and put a clear size label on the front and back of the packaging box. The partitions inside the box are also 1:1 separated according to the label to quickly find the size you need for work and improve efficiency.
  • 【Wide Range Of Applications】M3 socket head screws set is very suitable for professionals, amateurs, maintenance personnel, and other DIY people. In daily life, it is mainly used in scenes that require fine adjustments such as 3D printers, engines, bicycles, electric motors, motorcycles, small home appliance repairs, photography equipment, and DIY projects.

I love this assortment of screws, washers and nuts for my 3d printing needs. Although the whole package was smaller than I was expecting (size, not value). But, that just means less room taken up in the tech drawer they reside in. Here are some highlights on this item.1. many different lengths to choose from, with washers and nuts to match2. high quality metal, that seems to be of good tolerance, so they don't cross thread (at least so far)3. carry case makes getting the right size easy since they are all separated and you can easily grab and go4. value for money is great with sheer amount of total sizes included in the package.I am so glad I got these, as I wanted to make some jointed pieces on the 3d printer for home use. Now I can with no issues securing them together.

A perfect kit for a 3D printer hobbyist that always needs screws! M3 screws are always the type I'm seeming to need with all the boxes I make and this kit has come in handy so many times. I love that it's organized and labeled with a latching box that doesn't let them fly everywhere. The fact there is some wrenches included has been useful because sometimes it's just easy to grab it when it's right with the screws instead of running to grab one. It's a generous amount for the price and the screws feel high quality with no signs of wear. I highly recommend picking up this kit so that you always got what you need on hand!
