Headcovers, Adjustable Hosels and Wrenches

Many modern drivers, fairway woods and hybrids have an adjustable hosel, movable weights, or both. That makes a used wood more useful, because you can tune it to your swing, but it also adds parts that can go missing: the headcover, the torque wrench, the weights and the adapter sleeve itself. This guide covers what each does and what to ask about when a listing is vague.

Why a missing headcover matters

Headcovers exist to stop heads banging into each other in the bag. Golf Monthly describes iron covers as protection against clubs clanging together and damaging the heads, especially soft forged irons, and GOLF.com describes driver covers as protecting your most expensive clubs. A wood that has spent seasons without a cover is more likely to have nicks on the crown and top line from contact with irons.

• Ask for a photo of the crown taken at an angle to the light, which shows dents and paint chips that a straight-down photo can hide.
• Separate cosmetic from structural. Paint scuffs and small chips are cosmetic; dents, cracks or anything that catches a fingernail are not.
• A headcover in the listing is a small bonus, but it also suggests the club was looked after.
• If the club comes with a wet or dirty cover, Golf Monthly recommends drying headcovers and wiping clubs after rain to avoid problems in storage.

How adjustable hosels work

An adjustable hosel uses a sleeve bonded to the shaft tip that slides into the head and is held by a screw through the sole. Rotating the sleeve, or its rings, changes loft, lie and the face angle you see at address. GOLF.com notes the same sleeve also makes it easy to swap shafts between heads that use the same connector. Here is how the main systems differ, based on Golf Monthly's breakdown and the makers' own pages.

• TaylorMade loft sleeve: 12 positions with up to 2 degrees of loft change either way. Lowering loft opens the face at address and adding loft closes it. The STD setting is the flattest lie; every other setting is more upright.
• Ping Trajectory Tuning: Ping describes Trajectory Tuning 2.0 on the G430 as an 8-position hosel with loft adjustment of plus or minus 1.5 degrees and lie up to 3 degrees flatter than standard.
• Callaway OptiFit: Callaway says most of its drivers use OptiFit, with upper and lower cogs that rotate independently for 8 loft and lie combinations. Loft settings are -1, S (stated loft), +1 and +2; Golf Monthly lists the lie settings as Neutral and Draw. Because the cogs rotate, the shaft does not, so the grip and shaft graphics stay aligned.
• Titleist SureFit: a sleeve lettered A to D and a ring numbered 1 to 4, giving 16 combinations that change loft and lie in 0.75-degree steps.
• Cobra FutureFit33: Cobra says its current system adjusts loft and lie by up to 2 degrees in each direction across 33 settings, with loft and lie largely independent.

Cross-compatibility: what we could confirm

Buyers often want to know whether a shaft from an old driver will fit a newer head. GOLF.com's general answer is that swapping works between woods and drivers from the same brand in most cases, as long as the hosel connector type is the same. It also reported that Titleist kept its fairway wood adapter unchanged when it moved from TSi to TSR fairways, changing only the head internals. If you are pairing a used TSi3 or TSR2 driver with a spare shaft, the SureFit lettering on the sleeve is the first thing to photograph. The same goes for the loft-sleeve markings on a used TaylorMade Stealth 2 or Qi10 driver.

Beyond that, compatibility is brand- and generation-specific, and we could not verify a complete chart from the manufacturers for every family. Cobra, for example, sells separate adapters for its FF33 drivers and fairways, its FF33 hybrids and its other adjustable hybrids, which tells you not every Cobra sleeve fits every Cobra head. Before buying a shaft-only or head-only listing to pair with something you own, ask the seller to confirm the exact head model the sleeve came from, then check with the manufacturer or a club builder. Sleeves for drivers, fairways and hybrids are not always the same within one brand either.

The torque wrench

The wrench is a torque-limiting driver. GOLF.com explains that these wrenches are designed to release and click once the screw reaches the correct tightness, so you do not have to worry about over-tightening; turn until you hear the click. Cobra's instructions say to tighten clockwise until you hear a single, audible click, and not to tighten weights by hand because they can come loose during the swing.

You do not always need the original wrench, but you do need the right tip and torque. Cobra says its clubs can be adjusted with the Cobra wrench or any T25 torque wrench. For other brands, check the maker's adjustment guide before buying a generic tool; GOLF.com notes every major brand publishes one online. A regular hex key or screwdriver is not a substitute because it has no torque limit.

Movable weights

Many heads add sole weights that shift the center of gravity. Ping's G430 Max has a 25-gram movable backweight that can sit in Draw, Neutral or Fade positions. Cobra's OPTM drivers use 3, 7, 11 and 14-gram weights in different ports depending on the model. GOLF.com's general guidance is that a weight closer to the heel, usually marked as the draw setting, makes the face easier to close, while weight toward the toe or back does the opposite.

For a used club, the weights are part of what you are buying. Ask whether all original weights are present and installed, because a missing or swapped weight changes how the club plays and its swingweight. If the listing shows an empty port or a mismatched screw, ask about it.

When a listing says "no wrench" or "aftermarket adapter"

• No wrench: not a deal-breaker, but price in a compatible torque wrench and ask what setting the hosel is in now. Ask the seller to confirm the screw is tight and the head does not rattle.
• Missing screw: a head-only listing may not include the sole screw. Cobra notes its replacement adapters ship without screws and washers, so ask before assuming.
• Aftermarket or third-party adapter: ask who made it and which head it was built for, and ask for a photo of the sleeve markings. A non-original sleeve may not show the maker's setting labels, so you may not be able to tell what loft or lie you are playing.
• Shaft-only listing: confirm the adapter brand, the head family it fits, and the length the shaft was built to. The length depends on how much was trimmed for its original head.
• Glued or stuck sleeve: if the seller cannot loosen the screw, ask before buying. A sleeve that will not release defeats the point of adjustability.
• Settings photo: ask for a clear picture of the sleeve or ring markings so you know the current loft and lie before it arrives.
