How to Install Golf Ferrules

By Spencer Lanoue
July 24, 2025

Giving your irons a custom look with sparkling new ferrules is one of the most satisfying workshop projects a golfer can tackle. While that little plastic ring might seem purely decorative, a clean, perfectly installed ferrule showcases a true attention to detail and pride in your equipment. This guide will walk you through the entire process, from getting the old ferrule off to seating and finishing the new one for that seamless, professional transition you see on Tour bags. We’ll cover the tools you'll need, practical tips for a clean job, and the finishing touches that make all the difference.

What is a Golf Ferrule, Anyway?

Let's start with the basics. A golf ferrule is that small, typically plastic ring you see at the top of an iron's hosel where it meets the shaft. Its primary job is aesthetic. It creates a smooth, tapered transition from the wider hosel to the narrower steel or graphite shaft, covering up the sometimes-sharp edge of the hosel. Think of it as the crown molding for your golf club.

While a ferrule has no direct impact on how the club performs, its condition matters. A loose, cracked, or rattling ferrule is not only distracting but it can also allow moisture to get into the housing, potentially compromising the epoxy bond over time. More often than not, golfers replace them for two main reasons: they're installing a new shaft and want a fresh build, or they simply want to customize the look of their clubs with unique colors, stripes, or designs.

Essential Tools and Materials You'll Need

Before you get started, getting all your tools and materials in one place makes the entire process much smoother. Think of it like a good pre-shot routine. Here’s a checklist of what you should have on hand:

  • New Ferrules: Make sure you have the correct size. Iron shafts are typically .355" (taper tip) or .370" (parallel tip). The ferrule's inner diameter (ID) should match your shaft tip diameter.
  • Heat Gun or Micro Torch: A heat gun is safer for graphite shafts, but a torch works fine for steel if you're careful.
  • Shaft Extractor: This is the proper tool for safely pulling a club head without damaging the shaft. While not strictly for the ferrule, it's necessary for the complete process of an existing club.
  • Utility Knife with Fresh Blades: You'll need this for cutting off the old ferrule and scraping epoxy. A sharp blade is safer and more effective.
  • Measuring Tool: A set of vernier calipers is ideal for accurately measuring shaft and hosel diameters for a perfect fit.
  • Shafting Epoxy: Use a high-strength, 24-hour cure golf-specific epoxy. Don't use 5-minute hardware store epoxy, as it’s too brittle and can't withstand the impact forces.
  • Solvent: Acetone or mineral spirits are great for cleaning up uncured epoxy.
  • Shaft Prep Materials: A strip of sandpaper (80-120 grit) or abrasive cloth works perfectly for abrading the shaft tip.
  • Safety First: Heavy-duty gloves (like mechanic's gloves) and safety glasses are must-haves.
  • Lint-Free Rags: Paper towels or microfiber cloths are essential for cleaning.
  • Finishing Supplies: To achieve that pro look, you have a couple of options. The professional method uses a ferrule turning belt/machine. An great DIY alternative is using acetone and a cloth for a polished finish.

Step-by-Step Guide to Installing Golf Ferrules

This process is best done when you are reshafting a club or building one from components, as it allows for proper seating and finishing. Simply trying to replace a ferrule on an already-assembled club is much more difficult and often leads to-a subpar result.

Step 1: Get the Club Head Off

First things first, you need to separate the head from the shaft. This isn't the time to be a hero and yank - you need heat.

  1. Secure the club in a vise with a rubber shaft clamp to protect it.
  2. Gently and evenly apply heat to the hosel of the club head. If you’re using a torch on a steel shaft, keep the flame moving to distribute heat. If it’s a graphite shaft, use a heat gun, as a direct flame can destroy the shaft's resin. The goal is to heat the epoxy inside until it breaks down, which usually happens after about 60-90 seconds. You might smell it.
  3. Once hot, position your shaft extractor on the club and gently apply pressure. The head should pop off with a bit of a push. Don't try to twist it off.

Step 2: Remove the Old Ferrule and Clean the Shaft

With the head off, the old ferrule is now exposed. Gently heat it with your heat gun for a few seconds - just enough to make it pliable. Now, carefully take your utility knife and slice it lengthwise away from your body. You should be able to peel it right off. Be extremely cautious not to score the shaft, especially with graphite.

Next comes the a pivotal part: cleaning the shaft tip. Scrape off any large pieces of old epoxy with your knife. Then, use sandpaper or an abrasive cloth to sand the shaft tip down to its raw finish. You want to remove all old epoxy, paint, and chrome from the area that will be inserted into the hosel. This abraded surface creates a much stronger bond for the new epoxy.

Measure the insertion depth of the hosel and make sure you prep an equivalent length on the shaft tip, usually around 1.25 to 1.5 inches.

Step 3: Test-Fitting the New Ferrule

Before any epoxy gets involved, do a dry run. The new ferrule should be a very snug fit. You don't want it to slide on and off easily. For tapered .355" shafts, a ferrule with a .355" ID might even feel too tight initially. A great trick is to gently warm the ferrule for about 5-10 seconds with your heat gun just before sliding it on. It will expand just enough to go on smoothly.

Slide the ferrule onto the shaft tip and push it up well past the prep area. You'll set its final position against the hosel in the next step. Once it's on, wipe the shaft prep area down with a solvent-soaked rag to remove any oils or dust.

Step 4: Mix Epoxy and Install the Head

Now the magic happens. Following the package instructions, mix your professional grade, 24-hour shafting epoxy. A little goes a long way.

  1. Apply a thin, even coat of epoxy to the prepped area of the shaft tip using a popsicle stick or coffee stirrer.
  2. Next, dip your stick in the epoxy and coat the inside of the club head's hosel. This double-coating method helps achieve a complete bond with no air pockets.
  3. Push the shaft into the hosel with a slight twisting motion to evenly spread the epoxy. As you do this, slide the ferrule down the shaft until it sits snug against the top of the hosel.
  4. To make sure the shaft is fully seated, firmly "thump" the butt end of the club on the floor a couple of times. You might see a little bead of epoxy squeeze out between the ferrule and hosel - that's a good sign.
  5. Wipe away any excess epoxy immediately with a rag dampened with acetone or your preferred solvent. Check your grip and head alignment graphics one last time and set it aside to cure.

Step 5: Let It Cure

Patience is your most valuable tool here. Even though the epoxy might feel hard after a few hours, it needs a full 24 hours to reach its maximum strength and durability. Place the club in a corner where it won't be knocked over or handled. Don't even think about waggling it until that 24-hour mark has passed.

Step 6: Finish the Ferrule for a Professional look

This is the final step that separates the good job from the great one. The outer diameter (OD) of your new ferrule is likely a tiny bit larger than the hosel's OD. Your goal is to make that transition perfectly flush and smooth.

  • Method 1: TheAcetone Polish (DIY Friendly)
    For this method, you don't remove much material, so it's best when the ferrule is already very close in size. Fold up a clean, lint-free rag into a small, tight square. Dip a corner into acetone and gently but firmly wipe around the rotating ferrule. The acetone will slightly melt and smooth the plastic, blending it into the hosel and leaving a high-gloss finish. Wear gloves and do this in a well-ventilated area. A few steady passes are all it takes - don’t overdo it.
  • Method 2: Turning with an Abrasive Belt (The Pro Method)
    This requires a bit more equipment, like a dedicated ferrule turning machine or even a variable-speed belt sander clamped upside down. You use a fine-grit (around 320 or 400 grit) belt. Cradling the shaft, you gently and constantly rotate it while pressing the ferrule against the moving belt. The key is light pressure and constant rotation to remove material evenly until the OD of the ferrule is perfectly matched with the hosel. Once it’s flush, a final polish with acetone gives it that showroom shine.

Give your new build a final-wipe down, and you're done. You’ve successfully installed a new ferrule, giving your club a clean, custom, and professional look you can be proud of.
