When a stripped screw or a missing fastener stops a repair in its tracks, the last thing you need is to order from three different listings to find the right size. These A2 stainless steel pan head Phillips machine screws cover the full micro-to-small range from M1.0 to M3.5 in a single listing — 88 size combinations, from M1.0×3mm (0.12”) up to M3.5×60mm (2.36”), all in corrosion-resistant 304 stainless steel.
Each screw is manufactured to ISO metric thread standards. The pan head profile sits low and flat, distributing clamping force evenly across thin panels, plastic housings, and PCB surfaces without digging in. The Phillips drive is compatible with standard precision screwdrivers (PH000 through PH1, depending on size). Pack sizes of 10 or 50 pieces let you order exactly what you need — from a single repair to a workshop supply.
Typical applications include eyeglass frame repair (M1.0–M1.4), laptop hinge and keyboard assembly (M1.6–M2.5), electronics enclosures and PCB mounting (M2–M3), precision instrument housings (M2.5–M3.5), and any fine DIY project where standard hardware-store screws are simply too large or too prone to rust.

Measure the depth of the tapped hole or the thickness of the material being clamped. The screw length (excluding head) should engage at least 1.5× the thread diameter for a secure hold — for example, an M2 screw should engage at least 3mm of thread. Available lengths range from 3mm (0.12”) to 120mm (4.72”) depending on the diameter. When in doubt, size up.
A2 is the most common grade of austenitic stainless steel, equivalent to 304 or 18-8 stainless. It offers excellent corrosion resistance, is non-magnetic in most conditions, and is the standard material for precision fasteners in electronics, optical, and medical applications.
A2 stainless steel provides strong corrosion resistance and will not rust under normal indoor conditions or light outdoor exposure. For marine or highly corrosive environments, A4 (316) stainless is generally recommended. These screws are well-suited for electronics, eyeglasses, and indoor precision applications.
A Phillips precision screwdriver is required. Use PH000 for M1.0–M1.2, PH00 for M1.4–M1.6, PH0 for M2–M2.5, and PH1 for M3–M3.5. Always use a well-fitting driver — a loose or worn bit will strip the head on these small screws.
Yes. M1.0–M1.4 are standard sizes for eyeglass frames. M1.6–M2.5 are common in laptop hinges and keyboard assemblies. M2–M3 are widely used in electronics enclosures and PCB mounting. M3–M3.5 suit precision instruments and small structural assemblies. Always verify your device’s exact thread spec before ordering.
Yes — these are machine screws, not self-tapping. They require a pre-tapped M-series hole or a matching metric nut. They will not cut their own thread into plastic or metal.
A2 stainless steel typically has a tensile strength of around 500–700 MPa, which is generally sufficient for the light-to-medium clamping loads in eyeglasses, electronics, and precision instruments. These screws are not intended for structural or high-load applications. Do not overtighten — microscrews can shear if excessive torque is applied.
Available in packs of 10 or 50 pieces. The 10-piece pack is ideal for repairs and prototyping; the 50-piece pack suits workshop stock and small production runs. Select your preferred quantity using the Amount option above.
