Frequently Asked Questions

How does the Spring Bolt™ work?
All of our concealed Spring Bolt™ hardware works using the patented mechanics of one spring threading inside another spring.

First, drill a hole in the face of both pieces of rail you are joining. Then attach a spring to the bottom of both holes. Insert the alignment pin that comes with the kit into one of the springs.

At this time you can either apply glue to both surfaces or assemble dry to check the joint for fit. Assemble the joint by aligning one spring with the other and twist the pieces together until you have 3 to 4 full turns after the two surfaces have come in contact with each other.

No plugs or putty are needed since the Spring Bolt™ installation process does not penetrate the finished surface of the rail.

How precise do I have to be when drilling my holes?
Far less precision is needed to install a Spring-Bolt™ than is required with any other hardware. All you need is a hand-held drill with one drill bit and one driver and you will install a Rail Spring-Bolt™ in less than 2 minutes.
How well does the Spring Bolt™ work in terms of profile alignment?
Once installed, all of our Spring Bolt™ products allow for approximately 1/8” of movement in all directions providing for easy and perfect profile alignment.
I have used the Spring Bolt™ Rail Connector and I had issues with the screws snapping off. Are you using a good quality screw?
One of three things will happen when:

• You screw into wood

• The screw head comes into contact with wood and

• You give the screw an extra 1/2 turn or more

The screw will:

1. Pull itself a little deeper into the wood

2. Strip out or

3. Snap off at the head

Also take into account that end-grain wood does not compress, which will also make a screw more prone to

stripping or snapping.

In some cases you will be able to install a screw along side the one that broke. If the screw breaks, adjust the clutch on

on your drill or use a pilot hole for your screw.

The springs need to be secured to the bottom of the hole but do not need to be embedded into the wood at the base of the hole.

Our screws are made in America. We have had tests performed on the screws as they are being manufactured to ensure that they function as designed.

How much time does it take to install a Spring-Bolt™ and what tools do I need?
The Regular Rail Spring Bolt™ and the Rail-To-Post Spring Bolt™ will install in less that 2 minutes. The Post-To-Deck Spring Bolt™ will take 4 to 6 minutes to install*.

*All Spring Bolts™ require a drill, one drill bit and one driver.

How cost effective are your Spring Bolts™?
If labor is $1.00/minute and you complete a joint 10 to 15 minutes faster with the Spring Bolt™, then we can say that our product is the most cost effective post and rail hardware on the market.

Take jobs away from your competition by informing the customer you are using the best, most efficient hardware on the market.

It is invisible, has passed load tests, and is efficient!


Do you have different sizes of Spring Bolts™?

We have designed Spring Bolts™ for use on most of the connections you have to make to install a wood railing system.

· The Regular Rail Spring Bolt™ is designed to join railing fittings to standard size rails.

· The Super Spring Bolt™ is designed to join 2 pieces of straight, straight-to-bent or bent-to-bent rail. This size may also work for attaching a corner newel to a deck.

· The Rail-To-Post Spring Bolt™ is designed to attach rails to the face of block top posts or box newels. This size will also work for making rail fitting joints on large rail profiles.

· The Rail To End Post Spring Bolt™ consists of 2 pair of Rail To Post Springs. One pair of springs is right-hand threaded and the other pair of springs is left-hand threaded. Matching pairs are installed at each end of the rail. When the rail is twisted between two posts, both ends tighten at the same time. This is used to avoid the need to drill and PLUG the face of the newel located on the open end of a section of railing.

· The Post To Deck Spring Bolt™ is designed to attach a wood post to a wood or concrete deck.

Do you need blocking in the deck system for the Post-To-Deck Spring Bolt™?
Yes. Solid sub structure in the deck is needed for any post-to-deck hardware that will meet local code load requirements. We are not aware of any hardware that would pass a certified load test without the availability and use of a solid sub structure.
Does the Spring Bolt™ work on 90-degree rail joints?
Yes. The Spring Bolt™ gives you a huge advantage when making 90-degree rail joints. The Spring-Bolt™ allows you to make the joint in less than 2 minutes and gives you a perfect joint.

NO plugs, NO putty, and NO sanding!

What kind of glue do I use with the Spring-Bolt™?
Instructions are printed on the bag of every kit. The Regular Rail Spring-Bolt™ uses yellow wood glue. The Super Spring-Bolt™ uses epoxy. The Rail To Post and the Rail To End Post Spring-Bolt™ kits require no glue. You may use epoxy if you want to use some kind of glue. All Post To Deck Spring-Bolts™ use epoxy. We recommend 2-part Fasco 110 slow set. One pint will do 4 (four) Post Spring-Bolts™.
What do I need to know about the Spring-Bolt™ Epoxy?
Our slow set epoxy is required when using our Post-To-Deck Spring-Bolt™ Kit.

It is very important that the 2 parts of the epoxy are thoroughly mixed before placing epoxy in the spring holes. When you have thoroughly mixed the epoxy either place the epoxy in the hole immediately or spread the epoxy on your mixing board to create a thin layer. By spreading the epoxy over your mixing board there will not be a heat build up. Heat build up will render the epoxy unusable in a relatively short period of time.

What do I do if the hardware is installed and I want to make an adjustment to my cut?
Unscrew one spring from the bottom of the hole, trim the joint and reinstall the spring in the hole.
Can I make rail joints in my shop and take them apart for quicker assembly in the field?

Once the joint has been made (without glue) you can untwist a joint in a few seconds. Out in the field, you can twist the joints together dry to check for fit and then apply to make the joints permanent. This will cut down the time required on the job site.

Can the Spring Bolt™ be used for all joints?
No. The Spring Bolt™ will not work to attach a stair rail that is plumb cut to a post. The joints that will work with the Spring-Bolt™ are.
How strong is the Spring Bolt™ hardware?
Tests have been conducted in a certified laboratory using our Spring Bolts™ as per the instructions provided on each kit.

When required loads were applied to the railings they passed residential and commercial testing. In addition, we joined two 6” pieces of #6010 red oak rail using Tightbond II glue and a Regular Rail Spring Bolt™. While supported on both ends and ram pressure was applied to the center of the joint, our hardware held up to 1,368 lbs of force.

I used the Post To Deck Spring Bolt™ and the springs did not create a strong pulling force. Does that affect the strength of the joint?
No. The springs in the Post-to-Deck Spring Bolt™ Kit are designed to hold the post in position until the epoxy sets and cures. This requires a relatively small amount of pressure. Three or 4 turns after the post has come in contact with the post will create enough pressure to hold the post in place until the epoxy sets. This also allows for the post to be twisted in place without scratching the finish on the flooring. Once the epoxy has cured you will have the strongest post-to-deck attachment possible. In addition, there are no unsightly wood plugs to install.
Can I use Spring Bolts™ for my outside deck rails?
Yes. Our Rail-to-Post and Rail-to-End Post Spring Bolt™ Kits are made of stainless steel and come with stainless steel screws. We use a heavy gauge stainless steel wire for springs. The pull force is strong and forever constant. This will keep the joints tight when the moisture levels in the materials change with the fluctuating humidity.

We have a Post-to-Deck Spring Bolt™ Kit made for exterior use. The post kit comes with coated springs, a 7/8” x 6” aluminum post pin and stainless steel screws. The springs and the aluminum pin are encased in epoxy and so are not in contact with the wood or the air. As is the case indoors, the post-to-deck hardware requires blocking in the deck frame.

Can the Spring Bolt™ be used with composite railings?
Yes. Use the Spring Bolt™ hardware as directed on the packaging.
