HEXPHANT Button Head Socket Cap Screws, M3 x 25mm
Product description
Highlights
Some fastening jobs call for a compact machine screw rather than a general-purpose wood screw. This HEXPHANT pack includes 50 M3 x 25mm button head socket cap screws, made from black oxide 304 stainless steel (18-8) and fully threaded along the shaft. A hex socket drive gives you a direct way to tighten each screw with the included hex wrench.
The combination is aimed at furniture assembly, equipment, machinery maintenance, and household repairs. It makes sense if you need several matching screws for a project and want the tool included in the pack. The listing also describes the screws as suitable for indoor and outdoor use, with corrosion resistance from the stainless steel.
How to use it
Match the M3 thread size and 25mm length to the hole and joint in your project before starting. These are machine-thread screws, so they are intended for a compatible threaded connection, the product details do not specify a nut, insert, or other fastening hardware. The fully threaded design gives the screw threads along its length rather than a smooth shoulder.
For example, when replacing a missing fastener on a cabinet or workbench, compare the existing screw’s size and head style, then use the hex wrench to tighten the replacement. The button head is a distinct choice from a flush-style head, so it may not suit a surface where the fastener needs to sit flush.
Practical tips
Keep in mind that the listing provides no load rating or specific environmental rating. Although it describes 304 stainless steel as corrosion resistant and positions the screws for outdoor projects, that alone does not tell you how they will perform in a particular high-moisture or corrosive setting. For demanding structural work, choose fasteners based on the project’s requirements rather than relying on the general-purpose claims.
From the way it is set up, the useful part is the straightforward bundle: a stated size, 50 screws, and one hex wrench. That can be convenient for a repair where you want spares on hand. If your project needs a different head profile, thread size, or length, this pack won’t solve that mismatch, check those details against the parts you’re joining. A specialized fastener may be a better fit when the design calls for a particular head or application.
Questions before you buy
What comes in the pack? The listing specifies 50 screws and one hex wrench.
What drive do the screws use? They have a hex socket drive, and the included wrench is intended for tightening them.
Are they described for outdoor use? Yes. The listing states indoor and outdoor use and identifies the material as 304 stainless steel, but gives no specific exposure or load rating.
Final verdict
These are a practical match for repairs or assembly that call for M3 x 25mm fully threaded machine screws with a button head and hex drive. Not the best choice if you need a flush head, a different size, or a documented load or environmental rating. If those details match your project, the 50-piece pack and included wrench cover the basics without adding unrelated hardware.
