M3×10mm Stainless Steel Phillips Pan Head Machine Screw — A2, 50-Pack
The M3×10mm A2 stainless steel Phillips pan head machine screw is the go-to length for motor mounting, deep tapped hole assemblies, and stacked panel configurations where M3×8mm is insufficient. The 10mm length provides maximum thread engagement in standard M3 tapped holes and is widely specified for NEMA 17 stepper motor mounting in 3D printers and CNC machines.
Key Specifications

| Drive | Phillips (cross head) |
| Head Style | Pan head |
| Thread Type | Machine thread (metric coarse, 0.5mm pitch) |
| Quantity | 50pcs per pack |
| Standard | ISO 7045 / DIN 7985 |
Why Choose This Screw?
- 10mm for deep engagement — maximum thread engagement in standard M3 tapped holes; ideal for motor mounts, thick brackets, and stacked panel assemblies
- NEMA 17 motor mounting standard — M3×10mm is the standard screw for mounting NEMA 17 stepper motors to 3D printer frames and CNC machine motor mounts
- A2 stainless steel — corrosion-resistant for electronics, outdoor, and humid environments
- Phillips drive — compatible with all standard Phillips #1 screwdrivers
- 50-pack quantity — practical workshop stock for prototyping and production
Typical Applications
- NEMA 17 stepper motor mounting on 3D printers and CNC machines (M3×10mm standard)
- Stacked panel and bracket assembly (two 3mm panels + nut)
- Aluminium extrusion deep T-slot assembly with thick brackets
- Electronics enclosure assembly with thick walls or stacked components
- Robotics actuator and motor bracket mounting
- CNC machine axis motor and drive component mounting
Compatible With
- NEMA 17 stepper motors (M3 mounting holes, 10mm screw standard for most mounts)
- M3 T-slot nuts for 2020, 3030, 4040 aluminium extrusion
- M3 hex nuts, nyloc nuts, and flange lock nuts
- M3 flat washers and split lock washers
- Phillips #1 screwdriver; magnetic tip recommended
- 3D printer platforms: Voron 2.4, RatRig V-Core, Bambu Lab, Creality CR-10
Package Contents
- 50× M3×10mm A2 stainless steel Phillips pan head machine screws
Frequently Asked Questions
- Q: What screw length do I need for NEMA 17 motor mounting?
- A: M3×10mm is the most common length for NEMA 17 motor mounting. The NEMA 17 face has M3 tapped holes 4.5mm deep. With a 3mm motor mount bracket, M3×10mm provides approximately 6.5mm of thread engagement — sufficient for secure mounting. Some builds use M3×12mm for thicker motor mounts.
- Q: Can I use M3×10mm instead of M3×8mm for linear rail mounting?
- A: M3×10mm can be used for linear rail mounting if the T-slot nut thread depth allows. However, ensure the screw does not bottom out in the T-slot nut before the rail is clamped. M3×8mm is the standard for MGN9/MGN12 rail mounting; use M3×10mm only if your specific extrusion and nut combination requires it.
- Q: What is the maximum tapped hole depth for M3 screws?
- A: The recommended minimum thread engagement for M3 is 3×0.5mm = 1.5mm (3× pitch). For structural applications, 6–8mm engagement is preferred. M3×10mm provides up to 10mm of thread, suitable for tapped holes up to 10mm deep in aluminium or steel.
