RS PRO M3 5.5mm Steel Square Nuts, Bright Zinc Plated Finish

RS PRO Square Pressed Steel Nuts

Brought to you by RS PRO, these steel square nuts are a robust solution to fastening applications. With four broad sides, the nut can be easily gripped by pliers or spanners, with less chance of rounding off the bolt when tightening of loosening. They also retain a great level of surface pressure against the surface they are fastening against, which can help prevent unwanted loosening.
These mild steel square-headed nuts are bright zinc plated for an element of corrosion resistance, meaning they are suitable for many applications. They are most commonly combined with square-headed screws and bolts.

Applications

Square nuts can be used in common fixing and fastening applications, but their easy-to-grip nature means they can be turned more easily in blind spots or hard to reach places. Four-sided square nuts may be easier to grip than alternatives in certain situations, but they have disadvantages over a hex bolt as in there are less accessible angles in which to grip the nut.
