What Is The Bullet Hinge Solution Do You Need?

RF carries a variety of weldable hinges, including flat hinges, barrel hinges, adjustable hinges, round hinges, flag hinges, winged hinges and our most popular weld on bullet hinges. These hinges are good for welding on metal doors and lids when fasteners are not desired. The best popular type of hinges for welding is our bullet hinge, specifically designed for welded applications.

Some of the positive aspects of bullet hinges include:

lMore aesthetically pleasing to the eye than the old door hinge style

lTypically manufactured with tighter tolerances for better functionality

lComes in many sizes, metals and shapes

lCan be attached so that the door or gate can be removed by simply lifting it off

lCan be attached so that the door or gate can never be removed for security

lCan be purchased with grease fittings for ease of lubrication

Often the ends of the barrels will be tapered giving each end a bullet shaped tip. This adds to the streamlined appearance of the hinge.

Any time a metal door needs to hinge on a metal frame, a bullet hinge can be a great choice. Whether you are building or repairing a tool box, storage bin, gate, door, or safe box, there is probably a bullet hinge to suit your needs.

What Metals are bullet hinges Manufactured out of?

Another great thing about bullet hinges is that they can be purchased in plain steel, stainless steel or aluminum.

There are three main parts of a bullet hinge:

lThe pin or male side

lThe leaf or female side

lThe bushing

Typically, steel hinges will come with a brass bushing while stainless and aluminum hinges come standard with stainless steel bushings.

What are the Most Common Sizes of bullet hinges?

bullet hinges can be purchased from suppliers in lengths from 1.5″ to 10.5″ with as many as 20 sizes in between depending on the choice of metal used.

It is the body diameter that gives bullet hinges their sleek look. For instance, a 3.9″ long hinge will only have a body diameter of 0.6″.

A single 3 -3/16″ steel bullet hinge with a 5/16″ pin has the ability to hold up a 240 lb door or gate. And since hinges are most often used in pairs, two of these small hinges will hold close to 500 lbs.

Installation of bullet hinges

As with any hinge, alignment is very critical. And since bullet hinges are tight fitting they must be aligned even more precisely. There are a few ways to insure alignment is the best it can be.

One was is to simply use a straight edge keeping in mind it is the barrels that need to be aligned together. Be sure to mark or scribe a line on the post and door before welding the hinges to it.

Always tack weld the hinges to the gate and post with two tacks per side per hinge half. After doing this swing the gate fully open to fully closed to check for binding and proper fit.

If the hinges bind or do not fit properly, you will need to cut them off and re-align them.
