M4 x 5mm screws are short metric fasteners for applications that specifically call for a 4mm thread diameter and 5mm length. The MroMax truss-head set suits buyers seeking a small stainless-steel pack; the Yinpecly set is listed as a 50-piece option, but its product details conflict on length. MoyoCodi offers a hex-drive style, while METALLIXITY has a flat head. The VESA set below uses 10mm screws, so it is an alternative only when that longer length is required.
| Product | Head or drive | Pack size | Best suited for |
|---|---|---|---|
| MroMax | Truss head, Phillips | 15 | Short screws with a broad head |
| Yinpecly | Truss head, Phillips | 50 | Bulk buying, after confirming length |
| MoyoCodi | Button head, hex socket | 50 | Hex-drive fasteners |
| METALLIXITY | Flat head, Phillips | 50 | Applications requiring a countersunk head |
| VESA screw set | Phillips, with washers | 20 | Mounts calling for M4 x 10mm |
MroMax M4 x 5mm Truss Head Screws
Best for: Buyers who need a clearly specified short M4 screw in a smaller pack. The listed dimensions are 4mm thread diameter, 5mm thread length, and 0.7mm thread pitch. The Phillips truss head has a 9.4mm head diameter and a low profile, giving it a broader contact surface than a narrow-head fastener.
The 15 screws are made from 304 stainless steel, identified in the listing as 18-8, with stated corrosion resistance. This is a useful choice when the screw needs a wide head and the project calls for the exact 5mm length. The listing specifies a Phillips #2 drive.
Limitation: The pack contains only 15 screws, and the protruding head may not suit a countersunk or flush-finish installation.
Yinpecly 50-Piece Truss Head Set
Best for: Buyers looking for a larger pack of stainless-steel Phillips truss head screws. The product name says M4 x 5mm, and the features list a 4mm thread diameter and 0.7mm pitch. The listing describes the material as 304 stainless steel and includes 50 screws.
The quantity makes this set more suitable than the MroMax pack for a project requiring multiple fasteners or spare screws. However, the product data also states a screw length of 30mm, which conflicts with the name’s stated 5mm length. Check the item details with the seller before ordering if the length is critical.
Limitation: Because the listed length is inconsistent, do not assume these are 5mm screws without verification.
MoyoCodi Button Head Hex Socket Screws
Best for: Buyers who prefer a hex socket drive over Phillips. The product name identifies a 50-piece M4 x 5mm set, with button heads and black oxide 304 stainless steel. The package also lists one hex key, and the description states that the screws have a fully machine-threaded design.
This set offers a different head and drive style from the truss-head options. Choose it if the installation specifically accepts a button head and hex drive and the black finish suits the project. The listing describes the material as corrosion-resistant 18-8 stainless steel.
Limitation: The feature text gives the thread pitch as “5mm,” which conflicts with standard sizing information for the M4 x 5mm product title. Confirm the thread specification before purchase.
METALLIXITY M4 x 5mm Flat Head Screws
Best for: Buyers whose design calls for a flat, countersunk head. This 50-piece black set is described as carbon-steel Phillips machine screws, with an M4 diameter, 5mm length, and 8.2mm head diameter. The listing identifies potential uses in small electronics and other metal, plastic, or sheet-material connections.
The countersunk head distinguishes this product from the raised truss and button head choices. Select it when the receiving hole or surface is designed for a flat head; the Phillips drive is suited to a cross-head screwdriver.
Limitation: The listed material is carbon steel, not stainless steel. The product description does not establish the same corrosion resistance as the stainless-steel options.
VESA M4 x 10mm Screws With Washers
Best for: Buyers whose TV or monitor mount specifically requires M4 x 10mm screws—not 5mm screws. The set includes 20 black-plated carbon-steel screws, 20 split lock washers, and 20 extra-large flat washers. The listing names 75 x 75mm and 100 x 100mm VESA brackets and says the set is intended for devices requiring 10mm M4 screws.
This is included as a length-specific alternative for mount installations. Choose it only after checking the device or mount instructions for screw length and washer requirements.
Limitation: These screws are 10mm long, so they are not a substitute when the required length is 5mm. The listing also notes that the gasket cannot be disassembled.
Buying Guide: How to Choose M4 x 5mm Mount Screws
How do you confirm the screw size?
M4 refers to a nominal 4mm thread diameter; 5mm is the screw length specified by the listing. Verify the required length against the device or mount instructions, including whether the measurement is taken from beneath the head. Do not rely on a product title when its detailed specifications conflict, as with the Yinpecly listing.
Which head style should you choose?
Match the head to the mounting surface and hole. Truss heads have a broad, raised contact area. Button heads are also raised and use a hex socket in the MoyoCodi set. Flat heads are designed for countersunk applications. A screw that fits the thread can still be unsuitable if its head does not seat correctly.
Does material matter?
The listed stainless-steel choices include 304 or 18-8 material, while METALLIXITY lists carbon steel and the VESA set lists black-plated carbon steel. Consider the project’s environment and finish needs, but do not assume a coating or material offers a specific level of protection beyond the product information.
Should you buy a multi-piece pack?
Compare the quantity with the number of fasteners needed and keep length and drive type consistent across the project. A larger pack is not a better choice if its dimensions are uncertain or its head style does not fit.
Frequently Asked Questions
What does M4 x 5mm mean?
It identifies a metric screw with a nominal 4mm thread diameter and a specified 5mm length. Confirm the product’s thread pitch and measurement details before installation.
Are M4 x 5mm screws suitable for every monitor mount?
No. Mounts and displays can require different screw lengths. Follow the device and mount instructions; the VESA product listed here is M4 x 10mm, not M4 x 5mm.
Can a Phillips screw replace a hex socket screw?
Only if the application accepts that head and drive style. The correct tool must engage the drive securely, and the head must seat properly.
Which option has the most clearly stated 5mm length?
The MroMax and METALLIXITY feature details explicitly state a 5mm length. Yinpecly’s listing conflicts on length, and MoyoCodi’s feature details contain an inconsistent pitch specification.
