FST 115 Steel Iron Shafts

The FST 115 Steel Iron Shaft is lightweight and is designed to increase ball flight without sacrificing consistency and control.

Features:
  • .370" tip diameter
  • Lighter weight allows the clubmaker to use a lower center of gravity head or more head mass without increasing overall club weight

Trimming Instructions

FST 115 Steel Iron Shafts is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from Great performer for the average swing This shaft in the S/X flex is a great value and the ideal performer for the aggressive/fast swinger with a typical early hand release. And for such a player, it has great action at impact. It also launches high without ballooning to help gain a few extra yards. But because it has less than firm tip stiffness with a mid-kick point, it may feel a bit unstable at impact for the hard swinger with a Sergio Garcia-esque late hand release. But then again, that's not who it's really designed for. The FST 125 Pro would be better suited for such a swing. Also, this shaft feels a bit softer overall than the Dynamic Gold XP S300 which has a comparable bend profile.

Rated 5 out of 5 by from Great Shaft For My Longest Irons My swing speed is 103 MPH with a moderate tempo. I was playing a 4 and 5 hybrid but then I reshafted my 4 and 5 iron with the FST 115 shaft. I can hit the ball higher than with the similar Rifle shaft. The distance matches the hybrids and I love the soft, solid feel of this shaft. I am very pleased with the shaft, pricing and quality.

Rated 5 out of 5 by from Big fan of this shaft. Bought this shaft last year to replace a broken Taylormade Rocketbladez 4-iron as they don't sell the stock shaft. Once I shattered my 7-iron this year, I knew this was the shaft to buy again.

Rated 5 out of 5 by from Great shafts at a GREAT price I bought these shafts for a young man who needed stiffer shafts with higher ball flight and these are perfect.

I am trying to replace my 6 and 7 iron TaylorMade Burner 2.0 iron. They are 85 R shaft. Which shaft do I need? I usually need a little more than regular shaft but short of stiff. Firm is what I'm looking for. Swing speed 100-105.

Asked by: Buddy
The FST 115 (FS0012) could be a good replacement but is heavier then the stock 85 gram weight shaft in the Burner 2.0 irons. Another option would be the True Temper XP95 (TT0113). It is closer in weight to the 85 gram Taylor Made shaft with similar playing characteristics. https://www.golfworks.com/true-temper-dynamic-gold-xp95-steel-iron-shafts/p/TT0113/

Have Rocketbladez Max and the M flex graphite balloon. Swing is more to a regular flex. have a duplicate club with pro red. Great feel very consistent but too heavy for me. 115 regular?

Asked by: photopro
I do not have any specification on the FST Pro Red, not even a shaft weight. It was not a shaft we ever stocked. The FST 115 might be a lighter weight shaft but I just do not know for sure. The 115 is a very good shaft and is also a very consistent shaft from one to the next. You might want to get one and try it first before buying the whole set.

I don't hit my Rocketbladez high as I would like to. Also the stock shafts make the club lite and not controllable. Would these Get 115 launch higher?

Asked by: WMR
The stock steel shaft listed for the Rocketbladz irons was an 85 gram weight steel shaft designed to create a high ball flight. If the weight of the FST 115 shafts fit you better you may actually hit them higher and they could certainly help you to pace and time your swing better if the existing shafts feel to light.

What current shaft would give the same characteristics as the TM Reax 88 steel shaft regular flex soft stepped once? 5i SS 80 mph driver 93 mph, deliberate swing speed overall......

Asked by: Mogolf
I would use the True Temper XP95 R flex (TT0113) and follow the tipping instructions for the 5 iron to soft step it once. The 5 iron tip trimming is 2" and then you will install the shaft into the clubhead and cut from the butt end to your finished length. https://www.golfworks.com/true-temper-dynamic-gold-xp95-steel-iron-shafts/p/TT0113/

Would these shafts fit mizuno mx25 irons?

Asked by: Miller
No the MX25 Mizuno irons use a .355" taper tip shaft and the FST115 is only available in a .370" parallel tip which is to large to fit the Mizuno irons.

whats the difference between the fst 115 and the fst pro 115? and would these fit cobra f6 irons?

Asked by: james
The FST 115 (FS0012) and the FST 115 Pro Stepless (FS0013) is a stepless shaft. They have the same playing characteristics but the stepless one for some players will dampen some of the feel that the stepped shaft has.

Hi I have the cobra f6 irons. Would these fit and would these feel some what similar to the shafts on the f6?

Asked by: James
Yes these will fit the F6 irons and should match well to the stock steel shaft in these irons. The stock steel shafts were manufactured by FST and weighted 110 grams.

I have a set of titalist with ms 209 stiff shafts , are these .370 & would they play similar ? Thanks

Asked by: Sfrey
The Titleist irons use .355" taper tip iron shafts. The FST shafts will not fit. The FST shafts test and play more flexible then normal and would hit the ball higher then the MS 209 shafts.
