Sutemribor M5 x 30mm Button Head Socket Screws, 55-Pack, 10.9 Alloy Steel
Product description
At M5 x 30mm with a 0.8mm thread pitch, these Sutemribor screws are sized for assemblies that call for those exact dimensions.
The set contains 55 black, fully threaded button head socket cap screws made from 10.9 grade alloy steel.
Their internal hex drive is designed for use with a hex wrench, while the rounded button head gives the fastener a different profile from a traditional flat or raised-head screw.
Size & fit
The key buying check is the thread specification: M5 diameter, 30mm length, and 0.8mm pitch. Match all three to the receiving hole or existing fastener before choosing this set. The screws are fully threaded, so the threaded portion extends along the stated screw length rather than leaving an unthreaded shank.
This fixed size suits a repair or assembly where multiple matching fasteners are needed, such as a machine build or a removable panel. It is not a general assortment of sizes, if a project calls for another diameter, length, or pitch, this pack will not cover that requirement. The button head has a rounded top and a recessed hex drive, so allow for the head shape and access for a hex wrench in the intended installation.
Benefits
A 55-piece quantity can be useful when an assembly uses several matching screws or when a few replacements need to be kept on hand. The 10.9 grade alloy steel construction and black oxide finish are specified for this set. The manufacturer describes the steel as strong and wear- and corrosion-resistant, but the listing does not provide a load rating or detailed environmental limits, choose fasteners based on the demands of the actual joint rather than treating the material description as a guarantee for every setting.
Button head socket screws offer a rounded head with an internal hex drive, a practical combination for machinery and other assemblies that need to be fastened and later disassembled. Compared with buying a mixed-size assortment, this pack focuses on one specification, which is more useful when the required size is already known and less useful when a project needs several different fastener sizes.
Customer feedback in the supplied summary is positive about both perceived quality and function. Those impressions may help with a general sense of buyer satisfaction, but they do not establish fit for a particular machine or application.

Final verdict
A solid pick if your assembly specifically requires M5 x 30mm screws with a 0.8mm pitch and you want a multi-piece set with a black oxide finish. Not the best choice if the required dimensions differ, or if you need documented load or environmental ratings to select a fastener for a demanding application, those details are not provided here. Match the screw specification to the job before relying on the pack for a repair or build.
