Fischer 79734 kuusiomutteri

The fischer hexagon nut MU M (Fischer 79734) is a zinc-plated steel fastening element designed to secure components of the fischer installation system. Packaged as 100 pieces with a nominal width across flats of 13 mm, these hex nuts comply with DIN 934 and are intended for general fastening of bolts and threaded connections in construction and repair tasks.

Advantages

Zinc electroplating provides corrosion protection for the steel nut while maintaining mechanical strength corresponding to resistance class 8. Compliance with DIN 934 ensures standardized dimensions and thread compatibility with metric bolts, allowing reliable and repeatable assemblies. The packed quantity of 100 pieces supports larger projects and routine maintenance.

Suitable for

• Securing metric bolts and threaded rods in construction
• Assembly and repair of installation systems and metal frameworks
• General fastening tasks in maintenance and mechanical applications

How to use

Place the hexagon nut onto the corresponding metric bolt or threaded rod and tighten using an appropriate wrench or socket sized for 13 mm across flats. Ensure the mating threads are compatible with DIN metric threads and free of debris before tightening. For assembly, use recommended torque values for resistance class 8 bolts and nuts to achieve secure fastening without damaging threads.

Recommendations

Store the zinc-plated hex nuts in a dry environment to preserve the plating. For outdoor or highly corrosive environments, consider using higher-grade corrosion protection or stainless-steel alternatives if long-term exposure is expected.
