I accomplish the same thing as JE Custom's heat shrink tubing approach somewhat differently. JE's approach is easier than what I do, but if one has a lathe, and the time (I'm retired), machining brass studs and threading them is lots of fun. So is making the pillars.
Since you are bedding an SH Precision stock, you might consider getting a set of these washers. I've used them and they work great.
There are instructions for using them in the package and on the site.
I machine brass studs to use as tooling for the bedding job. They only have to be made once for each type of rifle so I've accumulated a relatively complete set.
Since my picture has pillars in it I'll discuss them as well even though you don't need them with the bedding block in your stock. I use an "N" drill diameter hole (.302") in the pillar. I machine the studs with 1/4-28 threads on one end, threads to match the threads in the action on the other end. The center section of the stud is between .2900 and .2950" in diameter so it centers in the pillar hole and insures that the 1/4" action screws won't touch the inside of the pillar anyplace in the finished rifle.
An example of pillar, stud, and nut - I don't remember which rifle this set was for:
The long threads on the nut end are so I can use a standard 1/4-28 nut as a lock nut when removing the studs prior to cracking the receiver free of the stock after the bedding cures.
I use the same type of studs when skim bedding HS stocks, and shim washers epoxied in place instead of pillars.
I use Kiwi Neutral paste wax as release agent. I coat the receiver with it, then polish it after it dries. I put some in the screw holes and all over the studs. I put some in the hole in the pillars using a Q-Tip being very careful not to get any on the end surface of the pillar.
I use a layer of 10 mil tape around the recoil lug and on the front surface of it. The back surface just gets a coat of polished Kiwi wax.
