Nuts and Bolts Assortment Kits, M3/M4/M5 x 8mm/12mm/16mm/20mm 304 Stainless Steel Screws, Casaon Allen Hex Socket Head Cap Precise Metric Screws with Nuts Set with Storage Box (440pcs);

More Practical and Cost-Effective, Save Your Time:
The Casaon flexible customized assortment would meet all your demands with comprehensive and well-organized variety sizes. When you want to use a certain bolt, you don't need to waste time running to the store to buy it separately, as it is already in your hand. A much more practical and cost-effective way to purchase hardware than individually.

304 Stainless Steel, Ensure Longer Time Using:
304 stainless steel is dependable and rigid strength as well as its rust and corrosion resistance. So, the screws are able to withstand drastic weather and temperature changes including placement within extremely humid areas.

Sharp Socket Cap Head, Nicely Finished Thread:
Adopting CNC cutting technology, the screw thread is very precise, clean, sharp, the nuts and bolts fit with each other properly and won't easily strip out from the screwdriver. There is no problem like you get with cheaper nuts and bolts, where threads are too tight or too loose. You can get these 'finger tight' before having to use tools for final tightening.
