M4 Stainless Steel Hex Nut A2 DIN934 50-Pack

M4 Stainless Steel Hex Nut — A2 DIN934, 50-Pack

The M4 A2 stainless steel DIN934 hex nut is the standard companion to M4 machine screws for aluminium extrusion assembly, electronics enclosure panel mounting, and structural robotics builds. M4 provides greater clamping force than M3 for heavier components and load-bearing joints. The DIN934 standard ensures compatibility with all M4 bolts, cap screws, and threaded rod.

Key Specifications

Why Choose M4 A2 Stainless Hex Nuts?

• M4 higher clamping force — M4 provides approximately 2× the clamping force of M3; preferred for structural joints, heavier components, and load-bearing assemblies
• DIN934 standard — internationally specified; compatible with all M4 bolts, cap screws, and threaded rod regardless of brand or origin
• A2 stainless steel — corrosion-resistant for electronics, outdoor, and industrial environments
• 7mm AF — standard M4 hex nut width; compatible with all 7mm spanners, sockets, and nut drivers
• 50-pack quantity — practical workshop stock for prototyping and production

Typical Applications

• Aluminium extrusion 3030 and 4040 T-slot assembly (M4 nut on T-slot bolt)
• Electronics enclosure panel mounting with M4 bolts
• Robotics chassis and structural bracket assembly (M4 for load-bearing joints)

Frequently Asked Questions

Q: What spanner size do I need for M4 hex nuts?

A: M4 DIN934 hex nuts have a width across flats (AF) of 7mm. Use a 7mm open-end spanner, socket, or nut driver.

Q: What is the thread pitch for M4 hex nuts?

A: M4 metric coarse thread has a pitch of 0.7mm. This is the standard pitch for M4 machine screws and is compatible with all standard M4 bolts, standoffs, and tapped holes unless specifically marked as fine thread (M4×0.5).

Q: What is the height of an M4 hex nut?

A: M4 DIN934 hex nut height is 3.2mm. This is important when calculating stack height for panel mounting and bracket assembly configurations.
