A2-70 304 Stainless Steel Phillips Wafer Head Screws M1.4–M6 Ultra Thin Super Low Flat Head Bolts

A2-70 304 Stainless Steel Phillips Wafer Head Screws M1.4–M6 — Ultra Thin Super Low Flat Head

A2-70 304 stainless steel Phillips wafer head screws offer the widest size range available — from M1.4 miniature screws for precision instruments to M6 for light mechanical assembly — all with an ultra-thin, super low flat head profile. The large-diameter wafer head distributes clamping load in thin materials while the stainless steel construction provides corrosion resistance for electronics, medical devices, and outdoor equipment.

Key Specifications

Why Choose A2-70 304 SS Wafer Head Screws?

Frequently Asked Questions

Q: What is the head diameter of a wafer head screw compared to a pan head?

A: Wafer head screws have a significantly larger head diameter than pan head screws of the same thread size, but a much lower head height. For example, an M3 wafer head has a head diameter of approximately 9mm vs 5.5mm for a pan head, but a head height of only 0.8mm vs 2.4mm for a pan head.

Q: Do these require a pre-tapped hole?

A: Yes. These are machine thread screws and require a pre-tapped hole or a nut. They are not self-tapping.

Q: What is the smallest size available?

A: The smallest size is M1.4, suitable for precision instruments, camera assemblies, and miniature electronics. Use a #000 Phillips screwdriver for M1.4 and M1.6 screws.
