SS304 SS316 Mushroom head 16mm - 200mm Length Square Neck Carriage Bolts
Description:
A round head square neck bolt carriage bolt or coach bolt is a form of bolt used to fasten metal to wood.
It is distinguished 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 round head square neck 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.
Round head square neck 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.
Round head square neck 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.
It is distinguished from other bolts by its shallow mushroom head bolt and that the shank cross-section of the bolt is circular for most of its length, but the portion immediately beneath the head is formed into a square section.Carriage bolts are designed to sink into the wood as you tighten the nut, essentially creating their own pockets. Except you're building with very hard wood, this should work fine.Carriage bolt is designed to sink into the wood as you tighten with nut, essentially creating their own pockets. Unless you're building with very hard wood, this should work fine. You can tap the bolts inward with a hammer as you tighten the nuts to assist.Carriage bolts are designed so that on one side of an assembly that there are no protruding bits for things to catch on. The round head part will provide that as opposed to there being a hex or square head sticking out. In your case with a chair kit the general idea is that the heads of the carriage bolts should face toward the side of the chair where the user will be. As such the threaded bolt ends will want to be down underneath or toward a generally non use for surface of the chair.

Application:
Round head square neck bolts finger round, but in general, the bolts used to connect two objects, usually through the aperture, and needs with the use of nuts, can not afford a single ligation. General tool with a wrench. Head mostly hexagonal top, generally larger. Usually do not need screw nut, cooperating directly with the two objects (general connection must first drilling, tapping), generally with a screwdriver tool (screwdriver), mostly slotted head, cross slot, hexagonal inside and outside a lot, generally small.
Advantage:
1. In dealing with the carriage wire timber provides an advantage. Pushed foundation poured on the crown of the trees, tighten the bolts in the nut, and a standard bolt needs a tool to tighten the bolts and nuts. Carriage bolt can use any standard bolt. However, if the surface material is difficult, such as metal, wire carriage bolt into the hole require the same square shank bolts tightened.
2. When used to determine the bolt carriage bolt position placement, marking the spot with a pencil drilling. Drill directly through the material as the drill bit protruding from the timber on the other side. Remove the screw hole drill carriage and place. This is good if it is a tight fit, as long as the hole. Place a waste timber peaceful carriage bolts, lag bolts hit with a hammer. Wood will tighten square shank. On the other hand, a washer and lock washer, then tighten.
