Kit contains 120 pieces across multiple M6 screw lengths plus matching nuts, washers and a wrench. Carbon steel parts receive nickel plating to improve hardness and resist corrosion.


Long-lasting corrosion resistance – Thanks to nickel-plated carbon steel

High-quality carbon steel undergoes a nickel plating treatment that forms a protective surface layer, reducing oxidation and surface wear. The plating helps the fasteners maintain dimensional stability during use.

Corrosion resistance keeps fixings serviceable in damp or variable environments, cutting the need for frequent replacements.

Secure, slip-resistant fastening – With hex socket head cap screws and uniform threads

Hexagon socket head cap screws distribute torque evenly across the head, while uniform pitch and clear threads reduce cross-threading and slippage during tightening.

Consistent thread engagement and reliable head contact result in predictable, secure clamping for assemblies.

Ready-to-use assortment – With 120 pieces including nuts, washers and a wrench

The package lists multiple M6 screw lengths alongside matching hex nuts and washers, plus a single wrench to allow immediate installation. Quantities suit a range of small to medium repair tasks.

A comprehensive set avoids repeated trips for missing fasteners and makes small jobs quicker to complete.
