Nut M4 Steel Zinc Coated, 7 mm thickness

Nut Rieksts M4 Steel Zinc Coated 7mm is a zinc-plated steel hex nut designed to mate with M4 threaded fasteners. The zinc coating provides basic corrosion resistance and a uniform finish, while the steel body offers mechanical strength suitable for general-purpose fastening in light to medium duty applications. With a 7 mm across-flats dimension, this nut fits standard M4 assemblies where compact, reliable fastening is required.

Advantages

The zinc coating reduces surface corrosion and improves durability in typical indoor environments. Steel construction ensures consistent thread engagement and load-bearing capability with M4 bolts and screws. A standard 7 mm across-flats size allows easy tightening with common hand tools and sockets. The nut's simple geometry and finish provide predictable performance in repetitive assembly and maintenance tasks.

Suitable for

• General mechanical assemblies using M4 threaded fasteners
• Indoor fixtures and furniture assembly
• Electronics enclosures and mounting brackets
• Prototyping and repair work requiring small hex nuts

Key specifications

• Thread size: M4
• Material: Steel
• Surface finish: Zinc coating (electroplated)
• Across-flats dimension: 7 mm
• Profile: Hex nut
• Typical use: Standard metric fastening

How to use

Match the nut to a corresponding M4 male thread and hand-start the nut onto the bolt or screw to ensure proper alignment. Use an appropriate 7 mm wrench, spanner, or socket to tighten to the required torque for the application, taking care not to over-torque and deform the threads. For repeated assembly and disassembly, inspect the zinc finish and threads for wear or corrosion and replace the nut if thread damage or significant coating loss is observed.

Usage recommendations

For improved corrosion resistance in humid or outdoor environments, consider using additional protective measures such as a thread-locking compound, a larger corrosion-resistant fastener (stainless steel), or sealing washers. When specific torque values are required, follow the bolt manufacturer's recommended torque for M4 steel assemblies to ensure secure fastening without damaging components.
