ROYMADE Newport-Style Putter Replacement Weights, 2 pcs 25g Tungsten Pair with O-Rings for Adjustable Swing Weight

ROYMADE replacement putter weights are a pair of screw‑in weights for Newport-style putters available in 5g, 10g, 15g, 20g, 25g, 30g, 35g, 40g and 45g to tune head mass and feel.

These aftermarket putter weights let you quickly adjust the swing weight and balance of Studio Select Newport-family putters without changing the head. Machined from aluminum, stainless steel or tungsten depending on weight, each pair includes rubber O-rings for a secure, moisture-resistant seal. They are sized for most Newport and many Select models but are not compatible with certain Squareback, Fastback, Detou or Newport Select M1/M2 series heads.

How do I use these weights to change feel and stability?

Swap one or both screws to increase or reduce the head mass and influence swing weight, smoothness and roll characteristics. Heavier weights add inertia for a steadier stroke while lighter weights make the head easier to accelerate.

• Available weights from 5g up to 45g for incremental adjustments
• Screw-in design fits Newport-style threaded cavities
• Use matching pair positions to maintain balance left-to-right

Which materials are used and why do they matter?

The set uses three materials selected for density and durability: aluminum for the lightest option, stainless steel for mid-range sizes and tungsten for the highest densities. Material choice affects the physical weight and the compactness of the piece, letting higher gram options stay small while adding mass.

• 5g: lightweight aluminum for minimal mass change
• 10g–20g: stainless steel for reliable mid-range tuning
• 25g–45g: tungsten for maximum mass in a compact form

Will these fit my Scotty Cameron or Studio Select putter?

These aftermarket weights are designed to fit most Studio Select Newport-style heads including many Newport, My Girl, California (including 2012), ButtonBacks, Select GoLo, Kombi, Futura X and numerous limited or tour variants. They are intended as direct replacements where the cavity and thread match.

• Compatible with many Studio Select and Newport-family models
• Not compatible with Squareback, Fastback, Detou or Newport Select M1/M2
• Includes rubber O-rings to help protect the cavity from moisture

Who is this for? These ROYMADE replacement weights are for golfers who tune putter feel—players, club techs and tuners who want fast, reversible swing‑weight adjustments without buying a new head. They suit owners of compatible Newport-style heads who need a range of mass options or replacement parts after loss or wear. If you need compatibility confirmation, compare your putter's weight cavity thread and diameter to the seller specs before ordering.
