HEXPHANT Machine Screws M4 x 20mm

If you need a specific replacement fastener, a correctly sized machine screw is more useful than a general-purpose assortment with dimensions you may not need. These HEXPHANT screws have an M4 x 20mm size, a pan head, and a Phillips drive, with 304 stainless steel construction. The pack contains 30 screws, so it suits a small repair or a project that calls for several matching fasteners. The important tradeoff is fit: the listed size and thread need to match the part you’re fastening.

Best use cases

These screws are intended for joining parts with compatible machine threads, including furniture repairs, woodworking projects, electronics, and general maintenance. For example, if a furniture fitting is missing a screw, you can compare the original fastener’s size and head style with these before replacing it. Their stainless steel material is described as corrosion-resistant, which may be useful where ordinary steel fasteners are a concern, but the listing does not establish how they’ll perform in every outdoor or marine environment.

Worth considering if you already know you need M4 x 20mm Phillips pan head screws and would rather buy a matching pack than sort through mixed hardware. It may not suit you if you need a different length, drive type, head shape, or a fastener selected for a specific load or exposure condition.

Product specs

• Size: M4 x 20mm
• Material: 304 stainless steel (18-8 grade)
• Head style: Pan head
• Drive: Phillips
• Thread: Fully threaded machine screw
• Pack size: 30 pieces

The stated measurements are the key details for matching a replacement. A machine screw must suit the threaded hole or compatible fastening setup, it is not interchangeable with every wood screw or general-purpose fastener. If the original part is unavailable, compare the screw you need with the listed dimensions and head style, rather than relying on appearance alone. Choosing without that measurement can leave you with screws that do not fit the job.

Where it shines

The practical appeal is a focused pack of one stated size and style, rather than a mixed assortment. That can make sense for repeat repairs or a project where several parts use the same fastener. The Phillips drive works with a Phillips screwdriver, and the pan head offers a rounded profile, whether that profile is right depends on the clearance and finish your assembly needs. Do you need a broad range of sizes, or a straightforward replacement for one known fastener? This pack is aimed at the latter.

The 304 stainless steel construction is the main material distinction from basic steel or zinc-plated screws. It is presented as offering better resistance to corrosion, but the product details do not provide a load rating or a specific environmental rating. For demanding structural work or conditions where failure would matter, select fasteners using requirements for that application instead of treating material alone as proof of suitability.

Is it worth it?

This pack makes sense when the dimensions, pan head, and Phillips drive match your repair, and having 30 pieces is useful for the job. It offers a clearly specified stainless-steel option for everyday fastening tasks without asking you to buy an assortment of unrelated sizes. The limitation is just as important: there is no stated strength rating, and the screws cannot solve a mismatch in thread or length. Choose them for a compatible, known-size repair, look for a different fastener when the application calls for another specification or documented performance.
