1. Product Description

Carriage screws by head size is divided into half of the head carriage screws (corresponding to standard GB / T14 and DIN693), small round head carriage bolts (corresponding to standard GB / T12-85). A bolts consisting of a head and a screw (with a threaded cylinder) are fastened to the nut and are used to fasten the connection of two parts with through holes.

A carriage bolt, coach bolt or round head square neck bolt is a form of bolt used to fasten metal to wood.

It is different from other bolts by its shallow mushroom head and that the shank cross-section of the bolt is circular for most of its length, as usual, but the portion immediately beneath the head is formed into a square section.This makes the bolt self-locking when placed through a square hole in a metal strap, or a round hole in most wood. This allows the fastener to be installed with only a single tool, a spanner or wrench, working from one side. The head of a carriage bolt is usually a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank.

Carriage bolts were developed for use through iron strengthening plates on either side of a wooden beam. It is commonplace though to use them to bare timber, the squared section giving enough grip to prevent rotation.

Carriage bolts are extensively used in security fixings, such as the Brenton Bolt where the bolt must only be removable from one side. The smooth domed head and square nut below prevent the carriage bolt from being unlocked from the insecure side.
