Rubber O-Rings for Screw-on Points

No one likes a loose, rattling field point. A while back, I found myself in one of those massive ‘hook and bullet’ stores where the plethora of contraptions and schwag facing the bowhunter borders on the ridiculous. In retrospect, I fully attribute my poor impulse control to subliminal messaging being piped through the Muzak in the store. I reluctantly forked over an ungodly sum for a small package of one dozen rubber o-rings. They are designed to slide over the ferrules of screw-in field points and/or broadheads so they set between the shaft and the point. The rubber o-ring would keep the point from coming unscrewed, which would stop my rattling dilemma, and also aid in fine-tuning the orientation of broadheads. Despite the hyper-inflated price, they worked very well—no more ratting field points, and easily adjustable broadheads.

With time, of course, I needed more o-rings, but I couldn’t bring myself to buy another dozen at those prices. That was when, as with most of my strokes of something approaching inspiration, I found myself wandering the local hardware store and it hit me—aquarium tubing; quarter-inch diameter, to be specific. I could buy a foot-long section of it for 25¢, or what would probably amount to a lifetime supply for a dollar. I plunked down my hard-earned quarter, took the tubing home and set to work with a small pocket knife, slicing off thin pieces and sliding them over the ferrules of my field points. These small pieces of tubing now have a place on all of my screw-in field points, blunts and broadheads, for a price I don’t have to think twice about.

    I like the idea of using a hose to cut your own…

    A bit of string wax around the threads also helps keep field points and broadheads from coming unscrewed. You can also vary the amount of wax to get that screw-in broadhead “just right” if you are OCD about its angle as you pull to anchor.

    Nice way to save some money. However when I tried the rubber o-rings I found my broadhead shafts bent easily and soon were not accurate.

    Nice, if you like tinkering. A drop of blue loktite on the middle threads works fine.

    Great idea, I have also used O rings in the past. Sometimes the low cost simple ideas is the best.

    O-rings or the tubing suggested is great for tweeking broadhead alignment, but for just keeping tips tight, I’ve never had one come loose when I rub the threads with string wax and snug them a bit with pliers.

    I have the same luck as Mike’s suggestion using string wax.

    For many years I have been using a small bit of clear nail polish to keep points screwed tight. It works, loosens when you want to change points, and is super-cheap at the $ store.
