Perno Cimco 190834 M4 acero galvanizado, longitud 20 mm, unidad

Cimco 190834 is a galvanized steel bolt with M4 metric thread and a length of 20 mm supplied as a single piece. It is designed for mechanical and assembly applications where a compact, standard M4 fastening is required. Galvanization provides a protective zinc coating that reduces corrosion risk in normal indoor environments and some mildly corrosive conditions, while the precise M4 threading ensures reliable engagement with matching nuts or threaded holes.

Advantages

The bolt’s galvanized steel construction offers corrosion resistance compared with untreated steel, extending service life in typical workshop and equipment environments. The standard M4 thread and 20 mm length make it compatible with a wide range of metric components and fixtures, simplifying parts selection and replacement. Supplied as a single piece, it enables small repairs or assemblies without purchasing bulk quantities.

Key specifications

How to use

Select a matching M4 nut or threaded hole with sufficient thread engagement for the intended load. Use the appropriate driver or wrench for the bolt head type (verify head form before installation). Tighten to the torque appropriate for M4 fasteners in galvanized steel, avoiding over-torquing to prevent thread damage or stripping. For assemblies exposed to higher humidity or outdoor conditions, consider additional sealing or a different corrosion-resistant grade if required.

Recommendations

Confirm thread compatibility and required length before installation. When reusing the bolt, inspect the zinc coating and threads for wear or corrosion and replace if damaged. Store in a dry environment to preserve the galvanization.
