NIB BOLT M/S (WITHOUT NIB) 10MM X 50

Quantity:

A nib bolt is similar to a cup square (carriage) bolt but includes small serrated nibs under the head instead of a full square neck. These nibs bite into the surface of timber or steel to prevent rotation when the nut is tightened. The domed head provides a clean finish and tamper-resistant fastening, while the nibs allow secure installation even where a square neck would not seat properly. Common Uses Timber structures and fencing Securing metal fittings to wood Trailer and gate fabrication General construction where a locking feature is needed without a square neck
