Brass nickel-plated hex nut M16, 19 mm across flats, thread step 1.6

Nickel-plated brass hex nut M16 with 19 mm across flats and a 1.6 mm thread pitch. This component combines the corrosion resistance and visual appeal of nickel plating with the electrical conductivity and machinability of brass. The hexagonal profile is machined to standard dimensions to fit a 19 mm wrench and mate with M16 x 1.6 bolts and studs, making it suitable for mechanical assemblies, fittings and visible fastenings where both function and appearance matter.

Advantages

The nickel plating provides increased surface hardness and improved resistance to oxidation, while the brass core maintains good electrical conductivity and ease of machining. The standard 19 mm across-flats hex form allows quick tightening and loosening with common hand tools. The 1.6 mm thread pitch is compatible with fine-thread M16 fasteners, offering secure engagement and better clamping precision compared with coarse-thread alternatives.

Suitable for

• Mechanical assemblies requiring corrosion-resistant fasteners
• Plumbing and fittings where appearance and conductivity matter
• Decorative fixtures and visible hardware in interior applications
• Electrical grounding connections needing conductive mating parts
• Replacement of M16 x 1.6 nuts in machinery and equipment

Key specifications

• Material: brass with nickel plating
• Thread size: M16
• Thread pitch: 1.6 mm
• Width across flats: 19 mm
• Shape: hexagonal nut
• Surface finish: nickel-plated (bright metallic finish)

How to use

Match the nut with a compatible M16 x 1.6 bolt or stud. Place the nut on the threaded component and turn clockwise by hand until finger-tight, then use a 19 mm wrench to secure to the required torque specified for the assembly. For disassembly, reverse the process using the wrench to avoid rounding the flats. Ensure threads are clean and free of debris before installation to maintain proper engagement.

Usage recommendations

For optimal corrosion resistance, avoid prolonged exposure to highly acidic or alkaline environments. When used in electrical grounding, confirm adequate clamp pressure for low-resistance contact. Apply appropriate torque values for brass fasteners to prevent deformation of the threads or hex flats; if required, use a torque wrench and consult assembly specifications.
