CSN 21401 hex nuts – Metric hexagon-head internal-thread fasteners – brass hexagon nuts
CSN 21401 hex nuts, also known as hexagon nuts, has metric coarse thread and fine thread. CSN21401 hexagon nuts are often used with bolts and screws.
Comparing the hex nuts metric coarse thread and fine thread, we can see that the self-locking ability and locking ability of the coarse hexagon nut are worse than that of the fine-tooth hexagon nut, but the locking force is greater than that of the fine-tooth hexagon nut; the fine-tooth hexagon nut has good locking performance, which is suitable for anti-vibration and easy to adjust the clearance, but the locking force is worse than that of the coarse hexagon nut, so it is suitable for the place where the clearance or torque should be adjusted.
In general, the coarse thread is used if there is no special requirement.
CSN 21401 hexagon nuts are one of the most common nuts available and are used with anchors, bolts, screws, studs, threaded rods and on any other fastener that has machine screw threads.
CSN 21401 Hexagon head nuts – Grade A (applicable to nominal thread diameter D ≤ 16 mm) and grade B (suitable for d > 16 mm) nuts are used in machines, equipment, or structures with small surface roughness and high precision requirements. It is characterized by a relatively large tightening force, which can be installed with a movable wrench, an open-ended wrench, or a spectacle wrench, all of which require a larger operating space.
Parts4world supply various of metric standard thread fasteners & custom thread fasteners. The CSN 21401 hex nuts, hexagon thread fasteners and other inch and metric industrial internal thread fasteners all are available for standard fasteners or custom requirements.
