M2–M6 304 Stainless Steel Allen Hex Socket Wafer Head Self-Tapping Screw — A2-70 Thin Flat Large Head
The A2-70 304 stainless steel Allen hex socket wafer head self-tapping screw combines a large-diameter, ultra-thin flat head with a hex socket drive for high-torque installation in tight spaces. The self-tapping thread cuts directly into wood, plastic, and thin sheet metal without pre-tapping, making it ideal for electronics enclosures, panel assembly, and PCB bracket mounting.

Why Choose This Wafer Head Self-Tapping Screw?
- Ultra-thin large head — maximum bearing surface with minimum protrusion; ideal where standard pan head is too tall
- Hex socket drive — higher torque than Phillips; no cam-out; compatible with standard Allen keys and hex bit drivers
- Self-tapping thread — cuts its own thread in wood, MDF, plastic, and thin aluminium sheet; no pre-drilling or tapping required
- A2-70 304 stainless — corrosion-resistant for indoor electronics, outdoor enclosures, and humid environments
- Metric sizing M2–M6 — covers the full range of electronics and light mechanical assembly
Typical Applications
- Electronics enclosure and instrument panel assembly (aluminium, ABS, polycarbonate)
- PCB bracket and DIN rail mounting in control cabinets
- Speaker cabinet and audio equipment assembly (wood/MDF)
- 3D printer frame and enclosure panel fastening
- Robotics chassis and servo bracket mounting
- Furniture and cabinetry assembly requiring flush, low-profile head
Compatible With
- Allen keys / hex bit drivers: M2=1.5mm, M3=2mm, M4=2.5mm, M5=3mm, M6=4mm hex
- Materials: wood, MDF, ABS, polycarbonate, HDPE, thin aluminium sheet (up to 1.5mm)
- Electric screwdrivers with hex bit adapters
Package Contents
- Self-tapping screws in selected size and quantity (per variant)
Frequently Asked Questions
- Q: What is a wafer head screw?
- A: A wafer head (also called thin flat large head or mushroom head) has a larger diameter than a standard pan head but a much lower profile. This provides a larger bearing surface to prevent pull-through in soft materials while keeping the head as flat as possible.
- Q: Can these screws be used in metal?
- A: Yes, in thin sheet metal up to approximately 1.5mm. For thicker metal, pre-drill a pilot hole slightly smaller than the screw's minor diameter. For structural metal fastening, use machine screws with a tapped hole instead.
- Q: What hex key size do I need?
- A: M2 requires 1.5mm hex; M2.5 requires 1.5mm hex; M3 requires 2mm hex; M4 requires 2.5mm hex; M5 requires 3mm hex; M6 requires 4mm hex.
