Sutemribor Socket Head Cap Screws, M2.5 x 4mm
Product description
Key specifications
Some repair and assembly jobs call for small, removable fasteners rather than a permanent connection. These Sutemribor socket head cap screws are M2.5 x 4mm, with a 0.45mm thread pitch, a black oxide finish, and a fully threaded design. The listed material is 12.9-grade alloy steel.
Their recessed hex drive is intended for use with a hex wrench, making them a practical format for parts that may need to come apart again.
The pack contains 105 screws. One detail to factor in: the supplied specifications don’t state the head dimensions or the wrench size, so tight-clearance projects may need more checking against your existing hardware.
Who it’s for
These are aimed at small-scale assembly and repair where the required screw size is already known. The product description lists machinery, removable panels and parts, instruments, electronics, household appliances, lighting, toys, and other compact projects as potential uses. That’s a broad range, but fit still depends on the thread and length your specific part requires.
It suits you if you need M2.5 screws with a 4mm thread length and want a quantity on hand for repeat repairs. For example, when reattaching a small removable panel, the socket head lets you tighten or remove the fastener with a hex wrench rather than relying on a slotted or Phillips drive. From the way it is set up, the value is in having matching small fasteners ready, not in covering multiple sizes.
Not the best choice if your project calls for a different diameter, thread pitch, or length. These are one specified size, not a mixed assortment, and the details provided don’t establish compatibility with any particular device or assembly.
In the box
The package includes 105 black M2.5 x 4mm socket head cap screws and a hex wrench. The screws are described as fully threaded, with a 0.45mm pitch and a black oxide finish. The wrench is included, though its size is not specified in the product details, if you need a precise fit for a tool you already own, that’s worth noting before you buy.
Questions before you buy
Are the screws fully threaded? Yes. The product details identify them as fully threaded, with a 4mm thread length.
What tool comes with the screws? A hex wrench is listed in the package. Its size isn’t stated, so the listing doesn’t confirm whether it matches a particular existing tool.
What should I match to my project? Check that M2.5 diameter, 4mm length, and 0.45mm thread pitch suit the part being fastened. The stated dimensions are the most useful basis for judging fit, the product details don’t provide head dimensions.
When it makes sense
Choose this pack when you already know that M2.5 x 4mm is the size you need and want a supply of removable fasteners for small assemblies or repair work. The 105-piece quantity can be useful for repeat jobs, while the included hex wrench means a basic tool is part of the package. The 12.9-grade alloy steel and black oxide finish are specified, but the description doesn’t give project-specific fit guidance or head measurements. If those details matter for a close-fitting installation, a screw with fully documented dimensions may be a better match.
