Customer Questions & Answers


What is the difference between this item and Model # 9001205? For which application is this item suited?
Asked by: keepingitallstraight
Thank you for your question Keepingitallstraight. our model# 9001205 is similar to 9400K-SBK-HD00R. The only difference is the length and quantity you get. model# 9001205 is 4-1/2" long and comes in a 2 pack, while the 9400K-SBK-HD00R is 3" long and is sold as a each. they are both used for rail to rail attachment. Depending on the length of your fittings once they and cut to size, you might need drill holes that require a shorter spring bolt. I would recommend using the 9001205 when joining straight rail to another straight rail. Thank you

5/8 in. x 3 in. Spring Bolt Fastening Kit is rated 4.2 out of 5 by 5.
Rated 5 out of 5 by from Railing Hardware This product was easy to use and allowed me to make a strong good looking joint on my railings. It only required a drill bit and a square drive. Tools I already had. I work with my hands for a living buy I think anyone could use this hardware. I liked not having to use wood plugs to cover my hardware after I installed it.

Rated 5 out of 5 by from Works like a dream!!! Couldn't believe how easy this was to use, I'm a skilled stair builder and have always used rail bolts in the past. Now that i found these i'm making the switch.

Rated 5 out of 5 by from "Spring Bolt" Works GREAT !!! I have had my railing parts for over 5 years only because I did not like the instructions on how to put it together. Thank goodness for Google !!! I found "Spring Bolt" and watched a few videos on YouTube. "Spring Bolt" works GREAT !!!

Rated 5 out of 5 by from Clever system I needed to create a continuous wood handrail for my customer. These springs were simple to install and structurally strong with epoxy
Date published: 2016-02-10
Rated 1 out of 5 by from no joint strength Used good 2-part epoxy and followed all installation instructions. The joint easily broke with little stress. The strength of the joint comes entirely from the glue, which is inadequate for any joints where sheer strength is desired. If it's a quick-install & walk-away job, these would probably be great. If you want a handrail that's going to hold up, don't even consider these - get the traditional rail bolts.
