Best M2 Self-Tapping Screws for Small Repairs and DIY Projects
The best M2 self-tapping screw set depends on the material, screw length, and how many sizes you need. The Xujinsongg kit is best for choosing among eight M2 lengths, while the HanTof set covers M2 alongside M2.5 and M3. Layboks offers a broader assortment for plastic and thin metal, WenTig focuses on small precision work, and uxcell is a straightforward choice when you need one specific M2 size.

Xujinsongg M2 Flat Head Assortment
Best for: DIYers who want several M2 lengths and a head designed to sit flush. This kit includes 800 screws in eight lengths, from 4 mm to 20 mm, making it useful when the thickness of the workpiece varies. Its nickel-plated carbon steel construction and cross-drive flat heads are intended for use with wood, plastic, and metal plates.
The screws are organized by size in a compartmented transparent box, which helps keep the short fasteners sorted. Choose this kit if you need M2 screws in multiple lengths rather than a mix of diameters. The listed dimensions are in millimeters, so check the required length carefully; these are very small screws.
HanTof 1200-Piece Mixed-Size Set
Best for: Buyers who need M2 screws but also work with slightly larger small fasteners. The black carbon steel assortment contains 1,200 Phillips pan head screws in M2, M2.5, and M3 diameters, each offered in 6, 8, 10, and 12 mm lengths. Sharp tips and deep threads are listed for fastening wood, plastic, and soft metal.
Compared with the Xujinsongg kit, this set trades longer M2 options for multiple diameters and a larger total count. The product advises using a low drill setting and torque below 12, and pre-drilling hard material. Avoid assuming the screws suit every metal or hard substrate; the listed applications focus on wood, plastic, and soft metal.
Layboks 625-Piece Small Screw Kit
Best for: Repairs that may call for different diameters in plastic or thin metal. The 625-piece black carbon steel kit includes 14 sizes across M2, M3, and M4, with Phillips pan heads. The product describes sharp tips and deep threads intended to help the screws penetrate plastic and thin metal.
This is a better fit than a single-diameter M2 pack when the repair requires flexibility across several screw sizes. Listed uses include electronics, appliances, toys, and furniture assembly. The size list is summarized as 14 sizes rather than specifying every size in the supplied product details, so confirm the assortment contents before buying if a particular length is essential.
WenTigDY M2 and M2.6 Precision Kit
Best for: Small mechanical equipment, eyewear frames, and electronic instruments where short screws are needed. The 400-piece kit contains M2 screws in 4, 5, 6, and 8 mm lengths, plus M2.6 screws in 6, 8, 10, and 12 mm lengths. Its listed applications include small electronics and instruments.
Choose this kit when M2.6 options are useful alongside M2 sizes. The product states that the screws can tap into plastic or wood and are intended for soft metal and thin wood. Its scope is narrower than a large mixed-size household assortment, and it should not be treated as a general-purpose fastener kit for heavy-duty construction.
uxcell M2 x 6 mm Stainless Steel Screws
Best for: Buyers who already know they need M2 x 6 mm screws and prefer a single defined size. This pack contains approximately 100 stainless steel Phillips pan head self-tapping screws in a silver tone. The listed head diameter is 3.5 mm, and the head thickness is 1 mm.
Unlike the assorted kits, this option avoids extra sizes you may not need. Its product details identify the material and dimensions clearly, which makes it useful for a repeat repair requiring that exact specification. The limitation is its fixed length and size: choose another assortment if you need different diameters or lengths.
Buying Guide: How to Choose M2 Self-Tapping Screws
Which screw length should you choose?
Match the length to the material thickness and the depth available behind the work surface. The listed M2 assortments range from short 4 mm screws to lengths of 20 mm. Measure the intended fastening point and check that the screw will not protrude where it should not. Confirm whether the listed measurement refers to the screw length you require before ordering.
Do you need a flat head or pan head?
Flat head screws are the relevant choice when a flush surface is desired. Pan head screws have a rounded, raised profile and may suit applications where a flush finish is not the priority. The product listings identify both styles, so compare head shape as well as diameter and length.
What material will the screws enter?
Several kits list wood, plastic, and soft or thin metal as suitable applications. A sharp self-tapping tip does not mean the screw is appropriate for every hard material. Follow the product’s guidance: the HanTof set recommends pre-drilling hard panels and using a low drill setting with controlled torque. Avoid overtightening tiny screws, which can damage the screw or workpiece.
Is a mixed assortment or a fixed-size pack better?
An assortment is practical for varied repairs, but a fixed-size pack makes more sense when the required specification is already known. Check the number of diameters, length options, head style, material, and storage method. M2 is a metric size; use millimeter measurements to compare it with the existing fastener.
Frequently Asked Questions
What does M2 mean on a self-tapping screw?
M2 identifies a metric screw size with a nominal 2 mm diameter. The length is listed separately in millimeters, such as M2 x 6 mm.
Can M2 self-tapping screws be used in plastic?
Several products in this selection list plastic as an intended material. Use a screw length and diameter suited to the part, and avoid excessive driving force that could damage the plastic.
Do self-tapping screws always need a pilot hole?
Not always. Some product listings describe sharp tips for starting in softer materials, while the HanTof assortment recommends pre-drilling hard panels. Follow the instructions for the specific screw and workpiece.
How do I keep tiny screws organized?
Use a compartmented box and keep each size in its labeled section. Separating screws by diameter and length makes it easier to find the right fastener and reduces mix-ups.
