However, I also realize that bed rail fasteners uk number style that screws into the end grain may have 3" long screws, whereas the style the screws across the end grain could not be more than about 1" screws or they would go through. Fang bolts or rail anchor bolts have also been used for fixing rails or chairs to sleepers. Retrieved The top surface of the plate bed rail fasteners uk number one or two shoulders that fit fastenere the edges of the base fssteners the rail.

There are a number of bed rail connector styles and I want to buy some high quality hardware that makes a very rigid connection. Without holding or testing them to get a feel for their rigidity, it's tough to tell from the pictures what will be rigid and what will allow the bed to flex. One thing I can say from looking at these pictures, is that I think the style that screws into the end grain of the rail may be weaker than the style that screws to the rail across the end grain simply because screwing into end grain is not as strong as across the grain.

However, I also realize that the style that screws into the end grain may have 3" long screws, whereas the style the screws across the end grain could not be more than about 1" screws or they would go through. Anyone have any first hand experience with various bed rail connections that can give tell me which ones are more rigid than others?

I don't think you need to overthink this, while there will be some that provide greater strength it's likely that any of the common solutions produce a bed that is rigid enough. In general this would be right, but screw type matters. The right screws both as to length and thread style can grip plenty strong enough for service in a joint subjected to longitudinal stress.

If only common screws are available though and you want to be extra sure the screws aren't going to pull out there's an old trick to increase their hold:. Equally, while the middle screw of three should be driven in straight the other two can be driven in dovetail-fashion to provide additional pull-out security. Many years ago probably close to 25 or 30 , my father built a set of twin bed frames for me and my bother as kids. For these, he used simple threaded rods epoxied into holes drilled into the end grain of the bed rails, which passed through holes on the bed legs.

These were bolted down with a nut and a washer on the outside of the leg. They held up to the two of us kids jumping around and doing other rambunctious kid stuff just fine, and I never remembered them creaking or swaying in any manner. We still use these beds, now stacked as bunk beds, in our family cabin, and they hold up just fine. If you don't like the look of the nut and washer on the outside of the leg, there are plenty of ways to dress it up.

Another similar system is to use "bed bolts. My dad and I used these in a baby crib for my nephew recently since they give a very tidy look compared to the through-bolt option.

Most recently, a Golden Spike marked the completion of the longest transportation tunnel in the world, the Gotthard Base Tunnel , which opened 1 June Full rail service began on 11 December Its functional length is A rail spike also known as a cut spike or crampon is a large nail with an offset head that is used to secure rails and base plates to railroad ties sleepers in the track.

Robert Livingston Stevens is credited with the invention of the rail spike, [6] the first recorded use of which was in A rail spike is roughly chisel-shaped and with a flat edged point; the spike is driven with the edge perpendicular to the grain, which gives greater resistance to loosening.

When attaching tie plates Double Hook Bed Rail Fasteners the attachment is made as strong as possible, whereas when attaching a rail to tie Hidden Bed Rail Fasteners or tie plate the spike is not normally required to provide a strong vertical force, allowing the rail some freedom of movement.

On smaller scale jobs, spikes are still driven into wooden sleepers by hammering them with a spike maul , though this manual work has been largely replaced by hydraulic tools [12] and machines, commonly called "spikers" a machine that removes spikes is called a "spike puller".

A dog spike is functionally equivalent to a cut spike and is also square in horizontal section and of similar dimensions, but has a pointed penetrating end, and the rail or "plate holding" head has two lugs on either side, giving the impression of a dog's head and aiding spike removal.

Chair screws are screwed into a hole bored in the sleeper. The chair screw was first introduced in in France French tire-fond and became common in continental Europe. A dog screw is a tradename variant of the screw spike. Fang bolts or rail anchor bolts have also been used for fixing rails or chairs to sleepers. The fang bolt is a bolt inserted through a hole in the sleeper with a fanged nut that bites into the lower surface of the sleeper.

For fastening flat-bottomed rails, an upper-lipped washer can be used to grip the edge of the rail. They are more resistant to loosening by vibrations and movement of the rail.

Spring spikes or elastic rail spikes [24] are used with flat-bottomed rail, baseplates and wooden sleepers. The spring spike holds the rail down and prevents tipping and also secures the baseplate to the sleeper. The spike maul , also known as a spiking hammer , is a type of sledgehammer with a long thin head which was originally used to drive spikes.

Manual hole drilling and spike or screw insertion and removal have been replaced by semi-automated or automated machines, which are driven electrically, by pneumatics, by hydraulics, or are powered by a two-stroke engine. Machines that remove spikes are called spike pullers. The earliest rail chairs , made of cast iron and introduced around , were used to fix and support cast-iron rails at their ends; [2] Best Bed Rail Fasteners they were also used to join adjacent rails.

In the s rolled T-shaped or single-flanged T parallel rail and I-shaped or double-flanged T parallel or bullhead rails were introduced; both required cast-iron chairs to support them. When inserted into the chair, exposure to the wet atmosphere caused the key Galvanized Steel Bed Rail Fasteners Home Depot to expand, firmly holding the rail. In Britain they were usually on the outside. Chairs have been fixed to the sleeper using wooden spikes trenails , screws, fang-bolts or spikes. In most of the world, flat-bottomed rail and baseplates became the standard.

However, in Britain, bullhead rail-and-chairs remained in use until the middle of the twentieth century. A tie plate , baseplate or sole plate is a steel plate used on rail tracks between flanged T rail and the crossties. The tie plate increases bearing area and holds the rail to correct gauge. They are fastened to wooden ties by means of spikes or bolts through holes in the plate.

The part of the plate under the rail base is tapered, setting the cant of the rail, an inward rotation from the vertical. The usual slope is one in forty 1.

The top surface of the plate has one or two shoulders that fit against the edges of the base of the rail. The double-shoulder type is currently used. Older single-shoulder types were adaptable for various rail widths, with the single shoulder positioned on the outside field side of the rails. Most plates are slightly wider on the field side, without which the plates tend to cut more into the outsides of the tie, reducing cant angle. Many railways use large wood screws , also called lag screws , to fasten the tie plates or baseplates to the railroad ties.

Tie plates came into use around the year , before which time flanged T rail was spiked directly to the ties. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate, one common one being the Pandrol fastener Pandrol clip , named after its maker, which is shaped like a stubby paperclip.

The newer Pandrol fastclip is applied at right angles to the rail. Because the clip is captive, it has to be installed at the time of manufacture of the concrete sleeper. Rail anchors, also called anticreepers, are spring steel clips that attach to the underside of the rail baseplate and bear against the sides of the sleepers to prevent longitudinal movement of the rail, either from changes in temperature or through vibration.
