Just installing this mount and thought I would check all bolts one last time with a small tug and SNAP! I can't @$#$% believe this...I emailed wolverine supplies about getting a replacement bolt, so hopefully they can find one.

Update: replacement bolt received and installed to correct torque specs...no issues, mount works great!

you have a few options to remove the bolt.

center punch and a hammer and tap the bolt in circles til you can twist it out.

or centerpunch the center and drill/extract.


is it tight in the threads? or is it loose?
 
Good call...it did eventually back out. There was just a little burr I could get a punch onto. It was tight in the threads, but it did slowly come out. That's great news!

Waiting game now for a new bolt.

Thanks
 
Don't be embarrased!!!

Lots of people probably broke some of the receiver bolt on the mounts; more than will admit it!!! Using the right tools helps; which is sometimes hard when they are expensive to acquire.
 
Once you broke off the bolt head, there was no preasure on the threads, thats why you could remove it. If you take a close look at your cylinder plug, you will notice that it's head and the bolt for the mount are the same, you can use your cylinder wrench to remove the mount when you need to. As suggested above and in the installation instructions for the mount the bolt should be torqued. Take care.

All should be well...will try with proper tools this time. The guys at wolverine are awesome and are sending a replacement bolt...I'm thinking that this isn't the first time someone has done this

Any time you are torquing using the "small tug" method you are asking for trouble. Doesn't have anything to do with the quality of the item involved. That is why there isn't a manual in the world in any field that says "give the wrench a small tug to set the final torque value".
 
There was a thread a while ago that had a photo of a scope base wrench on a piece of string. The wrench was about 4" long. With a 10lb rifle on a 1/3-foot long wrench, the weight of the rifle gives a 30 foot pounds torque setting.

that would make 40 inch/lbs or 3.3333 ft/lbs of torque, not 30 ft/lbs
 
if you ever find a replacement bolt, please let me know where and the SIZE!! I bought the so called DELUXE mount from Frontier, be surprised that the front bolt (the one goes into receiver left side) is too big to fit in:bangHead:

Don't ever use a replacement bolt other than that from the manufacturer. The ARMS bolt is designed to break when over torqued so you don't strip the threads in the receiver. Easier to replace the bolt than a buggered up receiver!

Next time use a torque wrench, it prevents the "tighten until it breaks, then back off 1/2 a turn" tightening procedures most of us follow.
